Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve

Answers

Answer 1

Answer:

15 equations

Step-by-step explanation:

Let

Number of equations in the homework = x

There is only a one-word problem

y = amount of time used to solve the word problem

She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,

Total = 3x + y

52 = 3x + 7

Subtract 7 from both sides

52 - 7 = 3x + 7 - 7

45 = 3x

Divide both sides by 3

x = 45 / 3

= 15

x = 15 equations

Therefore, she solved 15 equations

The sum of two consecutive numbers is 723. FInd the numbers.

Answers

Answer:

361 and 362

Step-by-step explanation:

a+b=723

b-a=1

b=1+a

a+1+a=723

2a+1=723

2a=723+1

2a=724

a=362

362+b=723

b=723-362

b=361

so b and a are 361 and 362 respectively

hence the consecutive numbers are 361 and 362

Answer:

48%

Step-by-step explanation:

If the coin is flipped 250 times, and lands on tails 120 times, set this up as a fraction. Put 250 on the bottom, and 120 on the top (because you want to know percentage of tails for 250 coin flips) to get 120/250. This is 0.48, to turn this into a percentage multiply by 100, 48%. You can check this answer by taking 0.48(250) and you will get 120.

Solve the following system of equations and show all work.

Please show all work

Answers

Answer:

-1/2 and -1

Step-by-step explanation:

Our system of equations is:

y = 2x²

y = -3x - 1

We can set the y's equal to each other:

y = 2x² = -3x - 1

Now, we have:

2x² = -3x - 1

Move all the terms to one side by adding both sides by 3x and 1:

2x² + 3x + 1 = 0

We must factor this quadratic. Note that the factoring is:

(2x + 1)(x + 1) = 0

Our solutions are now:

2x + 1 = 0           OR           x + 1 = 0

x = -1/2                                x = -1

.

Thus, our solutions are -1/2 and -1.

Answers

Answer:

5-( 2.40+1.33 )= $1.27

Step-by-step explanation:

If you add $2.40 to $1.33 you get $3.73, the total amount of money she spent on drinks and snacks. Then you would need to subtract $3.73 from $5.00, which is $1.27.

Answer:

Answers

Answer:

Step-by-step explanation:

Algebraically, both sides of the equation must equal each other.

[tex]4(12x-6)=6(-4+5x)+18[/tex]

Distribute

[tex]4(12x-6)=6(-4+5x)+18\\48x-24=30x-24+18\\[/tex]

Add, subtract, multiply, or divide to isolate x.

[tex]48x-24=30x-24+18\\48x-24=30x-6\\18x=18\\x=1[/tex]

The solution to this equation is 1.

To test, you can plug in x with 1 and you will see that both sides equal each other.

Answer: X=0

Explanation:
- Distribute 4 through the first set of parenthesis. It will be 48x-24=6(-4+5x)+10x
- Now distribute 6 through the second set of parenthesis. Now it will be 48x-24=-24+30x+10x
- Cancel equal terms on both sides of the equation (both of the -24’s) So it will be 48x=30x+10x
- Collect like terms (add 30x and 10x). You will get 48x=40x
- Move the variable to the left-hand side. It will be 48x-40x=0
- Collect like terms (Subtract 40x from 48x). You should get 8x=0
- Divide both sides by 8. X=0

1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent

3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.

Answers

Answer:

Step-by-step explanation:

1). Slope of a line shown on the graph will be,

   Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

              = [tex]\frac{-4}{1}[/tex]

              = -4

2). Slope of the given horizontal line can be determined by,

    Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

    Since, rise of the given line is zero.

    Therefore, slope of the given horizontal line will be 0.

3). Slope of the line passing through the indicated line = -2

    Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).

Answer:

Step-by-step explanation:

1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.

2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.

An album sells for $16.00 through an online music service. If the album is 10% off, and sales tax is 8%, what is the total price of the album including tax? A. $15.70 B. $15.68 C. $16.42 D. $15.55

Answers

Answer:  B. $15.68

Step-by-step explanation:

Given: Selling price of album = $16.00

Discount = 10% off

Sales tax = 8%

Discount = 10% of ( Selling price of album)

= 10% of $16

= 0.1 ($16)

= $1.6

Sales tax = 8% of ( Selling price of album)

= 8% of $16

= 0.08 ($16)

= $ 1.28

Total price of the album including tax = Selling price of album +Sales tax  - Discount

= $ 16 + $1.28 - $1.6

= $ 15.68

Hence, B. is the correct option.

John earns $7.50 an hour. How many hours will John have to work to earn $600?

Answers

Divide John's goal amount by his hourly rate to find the answer.

$600 ÷ $7.50/hour = 80 hours.

So, John will have to work a total of 80 hours in order to earn $600.

Answer:

80

Step-by-step explanation:

If you divide 600 with 7.50 you will get 80.

That is simple!

Find the GCD (or HCF) of numerator and denominator

GCD of 600 and 750 is 150

Divide both the numerator and denominator by the GCD

600 ÷ 150

750 ÷ 150

Reduced fraction:

4

5

Therefore, 600/750 simplified to lowest terms is 4/5.
