Step-by-step explanation:
392,153 rounded to the nearest ten thousand is 390,000
1) You add 72+89 which you get 161 and you divide by two and you get 80.5
2) you do the same thing 72+89+90=251
And you divide by three and you get ≈83.66
30 x + 15 y
15 (2 x + y)

Answer:
She bought 5 pounds of coffee.
Step-by-step explanation:
We are looking for how many pounds so pounds would be your x.
each pound costs $8.62.
You are taking the money she payed for the coffee away from the $70 she received.
Set up your equation
70 - 8.62x = 26.90
Solve for x
Subtract 70 from both sides 70-70 (Cancels out) - 8.62x= 26.90-70
-8.62x = -43.10
Divide -8.62 from each side. -8.62/-8.62(cancels out) x = -43.10/-8.62 (two negative numbers multiplied or divided by each other makes a positive)
x=5
