For this question, let's use algebra!

<u>2.5 miles</u> = <u>50 minutes</u>
1 mile x minutes

x minutes = 50 x 1 ÷ 2.5
x minutes = 20

Hope this helps!

The answer is b.

50 / 2.5= 20 (unit rate)

if Jenny walked 2.5 miles in 50 minutes, she walked 1 in 20 minutes becuase the unit rate is 20.

hopefully this helps

Rewrite the equation by completing the square.

dlinn [17]

Answer:

(x + 1/2)^2 = 289/4

Step-by-step explanation:

x^2+x-72=0

Write like this:

(x + ___)^2 = ___

put 72 on other side

x^2 + x = 72

x^ + x + (1/4) = 72 + (1/4)

(x + 1/2)^2 = 289/4

x + (1/2) = 17/2

What value(s) of x make the equation x2 - 18x + 81 = 0 true?

gayaneshka [121]

X^2 - 18x + 81 = 0
x^2 - 9x - 9x + 81 = 0
x(x - 9) - 9(x - 9) = 0
(x - 9)(x - 9) = 0
(x - 9)^2 = 0
x - 9 = 0
x = 9
