-5 1/4 + -3 how do you solve this problem

Answers

Answer:

8 1/4(Decimal:-8:25)

Step-by-step explanation:

simplify:

-51/4 - 3

=8 1/4 (decimal:-8.25)

Answer:

The answer would be 8 1/4

Step-by-step explanation:

-5 1/4 + (-3)

let's start with the whole numbers:

-5 + (-3) = -8 because it's just like adding positives but add a negative sign

so then we just add the -1/4 and you get -8 1/4

*you have to put the second number in parentheses because its how you properly write the equation Ex: -2+8+(-3)+(-1 5/6)=...

* also note that when you add two negatives it becomes a positive!!!

Jack bought a car for $29,000. He sold it for $10,000 3 years later. What is the percentage loss that Jack made?

Answers

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{65.51\% \: }}}}}[/tex]

Step-by-step explanation:

Given,

Cost price of a car ( CP ) = $ 29,000

Selling price of a car ( SP ) = $ 10,000

Since , SP < CP, there is a loss.

Loss % = ?

First, Finding the loss amount

⇒[tex] \boxed{ \sf{loss = cost \: price \: - selling \: price}}[/tex]

⇒[tex] \sf{loss = 29000 - 10000}[/tex]

⇒[tex] \sf{loss = 19000}[/tex]

Loss amount = Rs 19000

Finding the loss %

[tex] \boxed{ \sf{loss \: percent = \frac{loss}{cost \: price} \times 100\%}}[/tex]

⇒[tex] \sf{loss \: \% \: = \frac{19000}{29000} \times 100\%}[/tex]

⇒[tex] \sf{loss \: \% \: = \: 65.51 \: \%}[/tex]

Loss percent = 65.51 %

Answers

Answer:

the answer is 12z-2

Step-by-step explanation:

hope it help

Answer:

12z-2

Step-by-step explanation:

We are given the expression:

10z+2z-2

and asked to combine like terms.

First, let’s analyze each term.

10z : has the variable “z”

2z : has the variable “z”

-2 : does not have a variable

The like terms in this expression are the 2 terms with the variable “z”. Add the 2 terms, 10z and 2z.

10z + 2z -2

(10z+2z)-2

(10+2)z-2

(12)z -2

(12z)-2

12z-2

The expression 10z+2z-2 when simplified is 12z-2.

What is the solution to this system of equations?
x+y= 7
x = y + 3

A (5,2)
B (4,3)
C (2,5)
D (11/2, 3/2)

Answers

Answer:

A. (5,2)

Step-by-step explanation:

If you go to solve the equation you would first try to get y by itself in the first equation and you would do that by subtracting x on both sides. Then you would have y=7-x and then you would plug the second equation in for the x and get the equation y=7-y-3 because you distribute the negative sign of the x to both the y and 3. Then you combine like terms and get y=4-y and then add the y to both sides and get 2y=4 and then divide both sides by 2 and get y=2. Then you plug in y in the first equation and get x+2=7. Then you subtract 2 from both sides and get x=5.

What is the vertex of the graph of f(x) = |x-3| + 11?

Answers

Answer:

(3,11)

Step-by-step explanation:

we find the vertex of

[tex]g(x)=|x-3|[/tex] which is going to be (x,0)

and we add 11 (movement upward) so the vertex is (x,11)

vertex of g(x)

it is going to be when g(x)=0

and that only happens when x=3

so vertex (3,0)

so vertex of f(x)

(3,11)

if you don't believe i leave you the graph

The function f(x) = |x-3| +11 is in the vertex form which means vertex is (3,11)

Ill give 40 points to brainliest (in each word problem write the independent and dependent variable) A.You work part time at a grocery store and are saving money for a car. You already have $200 saved and you earn $12 per hour.B.You are driving on a road trip with your friends. You have 12 gallons of gas in your car and you use 0.10 gallons each mile you drive.C.You got a 60 on your test. You test grade will improve 2 points with each extra credit assignment you turn in.

Answers

Part A

independent variable = number of hoursdependent variable = total amount saved

The equation would be y = 12x+200 where x is the number of hours and y is the amount saved. The 200 is what you already have, and then you add on 12x additional dollars.

==============================================

Part B

independent variable = number of miles you drivedependent variable = amount of gas in the car

equation would be y = -0.10x+12. You start off with 12 gallons and each time you use up 0.10 gallons of gas for each mile you drive, so in total you use up 0.10x gallons

==============================================

Part C

independent variable = number of extra credit assignments turned independent variable = test grade

Equation is y = 2x+60. You add on 2x additional points to the 60 you already have

==============================================

Part D

independent variable = number of text messages sentdependent variable = total monthly bill

x is the number of messages and y is the total monthly bill, so the equation would be y = 0.25x + 35

==============================================

Part E

independent variable = number of cookies eaten per daydependent variable = total caloric intake per day

eating x cookies, at 120 calories a piece, means y = 120x is the total number of calories you consume per day. This is just considering the cookies of course and not other meals.

==============================================

In each case, the independent variable is the variable that is allowed to change and you know this value (or are given it). For instance, you know how many miles you drive and it varies. The dependent variable relies on the value chosen for the independent variable. So as x changes, then so does y.

Answers & Step-by-step explanation:

Let's define the two terms that we need to identify:

Independent variable: A variable that you have control over.

Dependent variable: A variable you cannot control and depends on other factors.

Jessica wants to slowly decrease her daily caloric intake, which is currently 2500 calories per day. She plans to decrease her calorie intake by 40 calories every 2 days for the next 30 days. Determine a reasonable domain and range for this situation.​

Answers

Answer:

i believe it should be E

Step-by-step explanation:

domain is x

range is y

since x is the number of days (0-30) the domain would be [0,30]

for y since she is decreasing 40 every two days that would be 15 days x 40 calories which is 600 (on 30th day)

subtract 600 from 2500 = 1900

so the range would be [1900,2500]

Answers

Answer:

Steps 1 and 2

Step-by-step explanation:

Henry applied the distributive property between steps 1 and 2.

The distributive property states that a(b + c) = ab + ac. In step 1, Henry used the distributive property to expand -3(x + 2) and 5(x - 7). This is evident when we rewrite step 1 using the distributive property:

Step 1 (using distributive property):

-3(x + 2) = -3 * x + (-3 * 2) = -3x - 6

5(x - 7) = 5 * x + (5 * -7) = 5x - 35

After applying the distributive property, Henry was able to simplify the equation and move on to step 2. The distributive property is a fundamental property in algebra that helps us expand expressions and make solving equations more manageable. In this case, it allowed Henry to eliminate the parentheses and combine like terms, bringing him closer to solving for the variable x.

Overall, the distributive property played a crucial role in transforming the original equation in step 1 into a simpler form in step 2, enabling Henry to continue solving the equation until he found the value of x in step 5.

the remainder when the polynomial f(x) =2x^3 + px^2 + qx 18 is divided by (x-1) is 10. When it is divided by x+1 the remainder is 12. Find the values of the consonants p and q

Answers

Answer:

p = 29 and q = -3

Step-by-step explanation:

Using long division, the remainder when we divide by x − 1 is p+q−16.  The remainder when we divide by x + 1 is p−q−20.

Therefore:

p + q − 16 = 10

p − q − 20 = 12

Add the equations together:

2p − 36 = 22

2p = 58

p = 29

Plug into either equation to find q:

q = -3

A box contains $7.45 in nickels, dimes, and quarters. There are 43 coins in all, and the sum of the numbers of nickels and dimes is 3 less than the number of quarters. How many coins of each kind are there?

Answers

Answer:

Number of nickels = 6

Number of dimes = 14

Number of quarters = 23

Step-by-step explanation:

Total number of coins = 43

Let number of nickels = n

Let number of dimes = d

Let number of quarters = q

[tex]n+d+q=43 ...... (1)[/tex]

Money in n nickels = [tex]n \times 0.05[/tex]

Money in d dimes = [tex]d \times 0.10[/tex]

Money in q quarters = [tex]q \times 0.25[/tex]

Total money = $7.45

[tex]0.05n +0.10d+0.25q = 7.45\\\Rightarrow 5n +10d+25q = 745 .... (2)[/tex]

The sum of the numbers of nickels and dimes is 3 less than the number of quarters.

i.e.

[tex]n+d=q-3[/tex]

Let us put the value  in (1):

[tex]q-3+q=43\\\Rightarrow 2q= 43+3\\\Rightarrow q =23[/tex]

Putting the value of q in (1) and (2):

n+d = 20 .... (3)

[tex]5n+10d+575 =745\\\Rightarrow 5n+10d =170\\\Rightarrow n+2d =34 .... (4)[/tex]

(4) - (3):

d = 14

Now, from (3):

n = 6

Number of nickels = 6

Number of dimes = 14

Number of quarters = 23
