Solve the following equation to find the value of x -3x + 4= 16

Answer:

Step-by-step explanation:

16 = - 4y - 12

Bringing like terms on one side

16 + 12 = - 4y

28 = - 4y

28/-4 = y

-7 = y

Answer:

It's in the air for about 2 seconds (A), maximum height was about 17 feet, and yes you win the price since 17> 15.

Step-by-step explanation:

Answer:

I know that 2 is 18

5 is the y intercept.

-Always the number without the variable.

Answer:

what are the questions hurry and tell me

Answer:

its either angle z and x or angle x and z

Step-by-step explanation:

Answer:

1. f(n+1) = f(n) + 0.09

2. The correct answer is 403 = x. The student’s error is that she did not cancel out properly the constant by the inverse add ended to find the answer of the variable.

3. B

4. D 34 + 6(25.3)

Answer:

9

Step-by-step explanation:

9 to the second power would be 9 times 9, which equals 81

Answer:

y=2/3x−4

Step-by-step explanation:

Answer: [tex]y=\frac{2}{3}-4[/tex]

Step-by-step explanation:

Slope[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\\=\frac{-4-0}{0-6}\\=\frac{-4}{-6}\\=\frac{4}{6}\\=\frac{2}{3}[/tex]

Since the line hits the y-intercept at -4 the answer is

[tex]y=\frac{2}{3}-4[/tex]

Answer:

Step-by-step explanation:

(92 - 12) – 4 = 2 (2 + for

4.0)

I

Answer:

D. identity

Step-by-step explanation:

- 6a + 3 = - 3(2a - 1)

First, distribute -3 within the parenthesis.

- 6a + 3 = - 6a + 3

Subtract 3 from both sides of the equation

- 6a = - 6a

Divide - 6 on both sides of the equation

a = a

We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity

For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.

I hope that this helps! :)

Answer:

she should preform division

Step-by-step explanation:

Answer:

Actually, it's C multiplication Cutty you can't be giving Wrong answers.

Step-by-step explanation:

It's C Multiplication because Were using the PEMDAS technique and this stands for

P- Parenthesis

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction

So if you see in the Pemdas technique It will be C Multiplication.

Answer:

2x2 = 4 + 2 = 6.

Step-by-step explanation:

Answer:

y= 2/5-1

Step-by-step explanation:

You get the 2/5 because you go 2 to the right and go 5 up, the -1 is because the x-int is at -1.

Answer: DE is 15 and AB is 6

Step-by-step explanation:

Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).

Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.

So, to find DE, just multiply the corresponding side, BC, by 300%.

5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?

For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.

Answer:

4x8=32

Step-by-step explanation:

Answer:

-n^3 – 5n + 4

Step-by-step explanation:

f(n) = -n^3 – 4

g(n) =  -n +4

f(n)+ g(n) = (-n^3 – 4n)+(-n +4)

               = (-n^3 – 4n -n +4)

               = -n^3 – 5n +4

Answer:

Step-by-step explanation:

Given Katiyln and lewis share sweets in the ratio =7:1

katliyn gets= 21 sweets

share of katiyln sweet =7x

share of Lewis sweet =X

So 7x=21 given

X=21/7

X=3

So Lewis gets x =3 sweets.

Question 8: w=7200

Step-by-step explanation:

2400/2=1200 is c is 1 so 1200x6=7200

Answer:

red

Step-by-step explanation:

The complete question is as follows;

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts

Solution;

The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams

Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams

So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts

Answer:

(30, 0) and (0, 50)

Step-by-step explanation:

( 0 , y ) are coordinates of y-intercept.

( x , 0 ) are coordinates of x-intercept.

25x + 15y = 750

25(0) + 15y = 750 ⇒ y = 50

( 0 , 50 ) are coordinates of y-intercept.

25x + 15(0) = 750 ⇒ x = 30

( 30 , 0 ) are coordinates of x-intercept.

Answer:

m = 0.28571428571

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29

Answer:

50/2.80= 17

Answer:

1. the perimeter of the first question is 22.5

2. true

5. 16.25

these are the only ones i remember how to do!

sorry :(

Hopefully someone fills in the rest of the answers!!!

Answer:

Question 1:

8/12 = 4/6 = 3/x

0.6 = 0.6 = 3/x

It is a similar triangle, therefore 3/x = 0.6

x = 5 because 3/5 = 0.6

Question 2

You did that correct :)

Question 3:

"Check all that apply"

B

D

Question 4

You got question 4 wrong since similar triangles have similar ratio.

8/10 = 8/10 = 10/14

0.8 = 0.8 = 0.7

Correct answer for question 4 is B("No they are not similar because the ratios are not equal")

Question 5

The Quadrilaterals are similar. Therefore:

22.4/14 = 12.8/8 = 12/7.5 = 26/x

1.6 = 1.6 = 1.6 = 26/x

Meaning 26/x = 1.6

x = 16.25

Because 26/16.25 = 1.6

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

[tex]4\text{ quarts}=1\text{ gallon}[/tex]

[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]

[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]

Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.
