Answer:

x = 9

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

= 2*11 + 2(x + 5) = 50

2x + 10 + 22 = 50

2x = 50 - 10 - 22

2x = 18

x = 9

Answer: 9

Step-by-step explanation:

2[(x+5)+11]=50

2[x+16]=50

2x+32=50

2x=18

x=9 There you go! So this is your answer. Your missing 'x' equals 9.

What is the y-intercept for the below inequality?

san4es73 [151]

Answer:

The correct answer is C

Step-by-step explanation:

In order to find the y-intercept, you need to first solve the inequality for y.

5x - 3y ≤ 15

-3y ≤ -5x + 15

y ≥ 5/3x - 5

Now we look at the constant at the end. Since that constant is -5, we know C to be the answer.
