What the answer to 6q-1=-q+20

1 answer:

8 0

If you add q to both sides, you'll end up with 7q and the q itself would cross out. So, you're left with 7q-1=20, add the one and you have 7q=21... 21/7= 3... q=3

Melissa buys a 10-pound box of apples. The box has 32 apples that are all identical. What is the weight of each apple in ounces?

Shalnov [3]

Answer:

Each apple weighs 5 ounces.

Step-by-step explanation:

This question can be solved using rules of three.

Each pound has 16 ounces.

So a 10-pound box will have 16*10 = 160 ounces

The box has 32 apples that are all identical. What is the weight of each apple in ounces?

So 32 apples have 160 ounces. How much does each apple weighs?

32 apples - 160 ounces

1 apple - x ounces

$32x = 160$

$x = \frac{160}{32}$

$x = 5$

Each apple weighs 5 ounces.
