Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.

Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

Kareem's mother's age, in years, is 5 years less than 8 times Kareem's age. If Kareem is k years old, which expression represents his mother's age? 5−8k years 5k−8 years 8−5k years 8k−5 years

Answers

8k-5 years.

k is his age so. 8 times his age would be 8k. 5 years less is 8k-5

Answer:

8k - 5

Step-by-step explanation:

since k represents kareems age, you would have to multiply that by 8. the expression 8•k can be simplified to 8k. the question states that the mothers age is 5 less than 8k, so the correct expression to represent the mothers age is 8k-5

2) -3 = -1 + b 2
3) 10 = b 16+ 9
4) -5 + x -14= -4
5) -176 = -5 - 9x
6) 1 = a 6- 2
7) -9 = -10 + x -18
