Answer:
Step-by-step explanation:
First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.
60 / 4 = 15
Now we divide their total of $210 by their hourly rate of $15 to find how many hours it would take.
210 / 15 = 14
I would take 14 hours to earn $210.
If im right brainliest plz
Hope this helps :)

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
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

Salama makes fruit baskets with oranges and bananas.
She uses between 8 and 16 oranges and bananas in a ratio of 3 oranges to 2 bananas.
Drag the correct number of fruit into the box to meet these requirements.
Answer:
9 oranges: bananas
Step-by-step explanation:
ok so I just did somthinglike this with my cuz so here is what I got
Ratio is 3 oranges : 2 bananas, They add up to 5 fruits, so some possible values are 5, 10, 15 , 20, 25, etc. We need a value between 8 and 16. This means that we need 15/5= 3 portions of fruits and since the ratio is 3:2
We multiply this by the original ratio to get 9 oranges : 6 bananas
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.”
