The way I like to solve proportions is by cross multiplying and dividing. First yo multiply the diagonals and then you divide by the other number. So if your proportion is 7/5 = x/3, your equation would be 7*3/5.  So 7*3 is 21, so your equation is now 21/5.  With some long division, you'll see that 21/5 = 4.2  That's your answer, feel free to ask more questions if you need!!(:

7/5=x/3
so multiply them diagonally. 7*3=21 and 5*x=5x
5x=21
divide it by 5
so....
5x/5=21/5
x=4.2

3. Jason uncle buys a 1.5 pound bag of pencils for the beginning of the year. He puts 1/2 of the pencils in a box. If Jason gets
Tems11 [23]

The quantity of pounds of pencils that Jason gets, based on his sharing ratio, is <u>0.15 pounds</u>.

<h3>What is the sharing ratio?</h3>

The sharing ratio is the percentage or ratio that is held by a person out of the total value of the thing being shared.

Jason's share of the pencil can be determined by multiplying the total pencils in the box (1.5 x ¹/₂) by Jason's sharing ratio (¹/₅).

<h3>Data and Calculations:</h3>

Quantity of pencils bought = 1.5 pounds

Half of the pencils in a box = 0.75 pounds (1.5 x ¹/₂)

The pounds got by Jason from the box = <u>0.15 </u>(0.75 x ¹/₅)

Thus, the quantity of pounds of pencils that Jason gets is <u>0.15 pounds</u>.

You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length.
s344n2d4d5 [400]

Step-by-step explanation:

So, x=width and the width=13+L. The formula for perimeter is 2(L)+2(W) and the total perimeter in this question is 62 feet. That means 2(L)+2(13+L)=62 feet. Solve for L and that's going to be your length. Add the length plus 13 and you'll have the width. Double check the equation by plugging the width and length back into the equation. (Does that help?)

Natali5045456 [20]

Answer:

$227

Step-by-step explanation:

First we can add up the withdrawals(63, 74, and 39) which is 176. We can then subtract 176 from 212 to get 36.

So, after the withdrawals Steven has 36 dollars.

We can add the deposits together to get 191. We can then add 191 to 36 to get 227.

What is the solution to the following system?<br> -4y=8 <br> x+3y-3z=-26<br> 2x-5y+z=19
Viktor [21]
⓵
-4ỿ = 8

Simplify the left side in order to isolate the ỿ!

-4ỿ = 8
+4 +4

Ỿ = 12

⓶
× + 3y - 3z = -26

Simplify the left side in order to isolate the ×, ỿ and z!

× + 3y - 3z = -26
÷3 ÷3

× + ỿ - 3z = -8,66 periodic
÷-3 ÷-3

× + ỿ + z = 2,88 periodic

⓷
2× - 5ỿ + z = 19

Simplify the left side in order to isolate the ×, ỿ and z!

2× - 5ỿ + z = 19
÷2 ÷2

× - 5ỿ + z = 9,5
÷-5 ÷-5

× + ỿ + z = -1,9
