The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.

X=y+4
x+y=20

now substitute the x for (y+4) in the second equation
(y+4)+y=20
2y+4=20
2y=16
y=8
now substitute 8 for y in the first equation
x=8+4
x=12
so y=8 and x=12

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished = 4,923.75ft²

Determine if the given ordered pairs are solution of x+ 4y = 7.

const2013 [10]

Answer:

(3, 1 ) is a solution

Step-by-step explanation:

To determine if the given points are solutions, substitute the x and y values into the left side of the equation and if equal to the right side then they are solutions.

(3, 1 )

3 + 4(1) = 3 + 4 = 7 = right side , then a solution

(2, 1 )

2 + 4(1) = 2 + 4 = 6 ≠ 7 ← not a solution
