Solve the following system of equations. What is the y value of the solution?

Svet_ta [14]

Answer:

y = 2

Step-by-step explanation:

x + 5y - 10 = 0

X = 4y - 8

since x is given as = 4y - 8 we can use this in first equation

replace x with 4y - 8

x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms

9y - 18 = 0 add 18 to both sides of the equation

9y = 18 divide both sides by 9

y = 2

The volume of a rectangular prism is 72 cubic centimeters. The prism is 2 centimeters wide and 4 centimeters high. What is the l

skelet666 [1.2K]

Answer:

The length of prism is <u>9 centimetres</u>.

Step-by-step explanation:

Given:

The volume of a rectangular prism is 72 cubic centimeters.

The prism is 2 centimeters wide and 4 centimeters high.

Now, to find the length of prism:

Let the length be $l$ .

Width = 2 centimeters.

Height = 4 centimeters.

Volume = 72 cubic centimeters.

So, putting the formula to get the length of prism:

$Volume = length\times width\times height$

$72=l\times 2\times 4$

$72=l\times 8$

Dividing both sides by 8 we get:

$9=l$

Length = 9 centimetres.

Therefore, the length of prism is 9 centimetres.

4. Bryce has 220 feet of fencing that will enclose a rectangular corral. One side of the corral will be 48 ft long. What will be

RideAnS [48]

Answer:

The area of the rectangular coral = 2,976 ft²

Step-by-step explanation:

Bryce has 220 ft of fencing to fence a rectangular coral.

Let the dimensions of the corral be x ft. × y ft.

One side of the coral is 48 ft. long

A rectangle has 4 sides, with each of the two opposite sides with the same dimension. Hence, the perimeter of the rectangular coral = 2(x + y) = 2x + 2y.

Total length of material for fencing = 220 ft.

Hence the perimeter of the reef = 220 ft.

2x + 2y = 220

And one length of the rectangular coral = x = 48 ft.

We can solve for the remaining dimension of the rectangular coral this way.

2(48) + 2y = 220

2y = 220 - 96 = 124

y = (124/2) = 62 ft.

Hence, the area of the rectangular coral = xy = 48 × 62 = 2,976 ft²

Hope this Helps!!!

ANSWER ASAP GIVING BRAINLIEST AND STUFF!

AURORKA [14]

Answer:

You could make a proportion, and divide or subtract the colors you like the least. Then, take the ones that you like the least away and put them in a separate place away from the others. For example: You have five colors, right? Ok, lets say your colors are blue, charcoal gray, yellow, green, and lilac.

Lets say your favorites are charcoal gray, lilac, and blue. (3/5)

So you put yellow and green to the side (2/5)

For example: You have 6 wallpaper patterns, right? Lets say your patters are flowers, dots, lines, stars, circles, and zigzags.

Lets say your favorites are flowers and stars. (2/6 or 1/3)

So you put dots, lines, circles, and zigzags to the side. (4/6 or 2/3)

Now, I want you to narrow your favorites down to what you favor more out of them. Now you have 3 paint colors, right? Your colors are charcoal gray, blue, and lilac. You need to narrow it down to 1 favorite. Lets say you choose the the lilac best.

Now you have 2 patterns, right? Your patterns are flowers and stars. You need to narrow it down to your favorite pattern. Lets say you choose the stars.

So, you will paint your wall lilac with the pattern of stars.
