Answer:

The solution would be (0, 5)

Step-by-step explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

4x + 4y = 20

4x + 4(x + 5) = 20

4x + 4x + 20 = 20

8x + 20 = 20

8x = 0

x = 0

Now that we have the value of x, we can find the value of y.

y = x + 5

y = 0 + 5

y = 5

Help please !! thank youu

Answer:

d = √91 ft = about 9.53 ft

Step-by-step explanation:

use pythagorean theorem which is a²+b²=c²

(the hypotnuse which is opposite side of the right angle is always going to be C in the pythagorean theorem)

a = 3    b = ?     c = 10

(3)² + b² = (10)²

9 + b² = 100

subtract 9 from both sides

b² = 91

take the square root of both sides

b = ±√91

so the side d = √91 ft = about 9.53 ft
