Answer:

9

Step-by-step explanation:

(-9)^1/3 * (-81)^1/3

We can rewrite -81 as 9 * -9

So it can be rewritten as:

(-9)^1/3 * (9*-9)^1/3

Since they are all raised to the 1/3, we can combine the bases:

(-9*9*-9)^1/3 =

(9*9*9)^1/3, because the two negatives turn into a positive:

So this is basically:

(9^3)^1/3 = 9^1 = 9

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What
Kitty [74]

We are given : Cost of a gallon of milk = $2.50.

Cost of a cup of yogurt = $1.20.

Total money Monica has = $20.

Number of cups of yogurt Monica can buy = x.

And inequality made is also correct

1.20x + 2.5 ≤ 20.

Now, we need to solve it for x.

Subtracting 2.5 from both sides, we get

1.20x + 2.5 -2.5 ≤ 20 - 2.5.

1.20x ≤ 17.5

Dividing both sides by 1.20, we get

1.20x/1.20 ≤ 17.5/1.20.

x ≤ 14.5833...

Because it's less than 15, so final answer is : 14 is  greatest number of cups of yogurt Monica can buy.
