6x - 2y = 32

4x - 2y = 18

------------------- -

2x = 14

x = 7

4x - 2y = 18

4(7) - 2y = 18

28 - 2y = 18

-2y = -10

y = 5

Answer:

x=7, y=5

Step-by-step explanation:

6x-2y=32

4x-2y=18

Subtract the second equation from the first equation

6x-2y=32

- 4x-2y=18

------------------

2x = 14

Divide each side by 2

2x/2 =14/2

x=7

Now substitute x=7 into the first equation to find y

6*7-2y=32

42 -2y = 32

Subtract 42 from each side

42-42 -2y = 32-42

-2y = -10

Divide each side by -2

-2y/-2 = -10/-2

y =5

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is $V=a^3$

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

$V=\frac{500}{4}=125\ ft^3$

Substitute in the formula to get the side,

$125=a^3$

$a=\sqrt[3]{125}$

$a=5\ ft$

We know, 1 feet = 12 inches

So, 5 feet = $5\times 12=60$ inches

Therefore, 60 inches long are the sides of the pillars.

Tom has a large photo he wants to shrink to wallet-sized. It's width is 20 centimeters and it's len is 30 centimeters. If he wan

dsp73

We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?

We can set up the proportion as :
width 1 : length 1 = width 2 : length 2

20 : 30 = 5 : x

We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)

20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm
