Answer:

9 is 25% of 36

Step-by-step explanation:

We have,  25 /100x = 9

Multiplying both sides by 100 and dividing both sides by 25,  we have

x = 9 ×  100 /25

x = 36

s2008m [1.1K]

Answer:

Step-by-step explanation:

To multiply 4×5⅜, the mixed number can be broken down into a whole number and a fraction. In this case, that whole number would be 5 and the fraction would be three-eighths. Each of these parts are then multiplied by 4 and the products are added together.

4×5⅜ = 4×(5+⅜)

= 4×5 + 4×⅜

= 20 + 3/2

= 20 + 1½

= 21½

Describe the total change to Ms. Thomas' savings account balance after making six monthly payments on her car loan. Model your a
Butoxors [25]

Answer:

$-1465.5

Step-by-step explanation:

Complete question

Every month, Ms. Thomas pays her car loan through automatic payments (withdrawals) from her savings account. She pays the same amount on her car loan each month. At the end of the year, her savings account balance changed by −$2,931 from payments made on her car loan. Describe the total change to Ms. Thomas’ savings account balance after making six monthly payments on her car loan. Model your answer using a number sentence.

Given the following

Savings balance (after 1 year) =

−$2,931

If she pays the same amount on her car loan each month, we are to find the total change to Ms. Thomas’ savings account balance after making six monthly payments on her car loan, this can be expressed as;

$x = 6months savings

Solving both equalities

Savings balance (after 1 year) =

−$2,931

Since 1year = 12months

-$2,931 =12months savings

$x = 6months savings

To get the total savings after 6months we will find x by cross multiplying;

12×x = -2931×6

Divide through by 12

12x/12 = (-2931×6)/12

x = -2931/2

x = -1465.5

Hence Ms. Thomas' savings account balance after making six monthly payments on her car loan is $-1465.5

Which of the following equations has the same solutions as the equations 3x+2y=-12
Marianna [84]

B, C, E, F

<h2>Explanation:</h2>

In this problem, we have the following equation of a line written in Standard form:

3x+2y=-12

So  we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.

Option B.

-3x-2y= 12 \\ \\ Multiply \ both \ sides \ by \ -1: \\ \\ (-1)(-3x-2y)=(-1)(12) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option D.

15x+10y= -60 \\ \\ Multiply \ both \ sides \ by \ 1/5: \\ \\ (\frac{1}{5})(15x+10y)=(\frac{1}{5})(-60) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option E.

6x+2y= -12 \\ \\ Multiply \ both \ sides \ by \ 1/2: \\ \\ (\frac{1}{2})(6x+2y)=(\frac{1}{2})(-24) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option F.

1.5x+y= -6 \\ \\ Multiply \ both \ sides \ by \ 2: \\ \\ (2)(1.5x+y)=(2)(-6) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.

IgorLugansk [536]

Answer:

x=7

Step-by-step explanation:

The two marked angles in the image are supplementary, so we can form the following equation:

2x-3=x+4

We can solve that equation to find <em>x</em>.

2x-3=x+4

2x=x+7

x=7
