John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beings of 5 to 1. If he wants to use a total of 90 cans how many cans of green beans should he use?

Answers

Okay, so the ratio is 5 to 1, which is a total of 6 cans. He wants to use 90 cans.

90 / 6 = 15 groups of 6 cans

Since he wants to use one can to every 5 pumpkin cans, then he will use 15 green bean cans. ( one green bean can in every group of 6 total cans )

Double check: 15 + 5 ( 5 pumpkin cans per group of 6 total cans ) * 15

15 + 75 = 90

So yes, it is true.

How do you solve 7a-3=3+6a

Answers

The calculated value of a in the equtaion is a = 6

How to calculate the value of a in the equtaion

From the question, we have the following parameters that can be used in our computation:

7a-3=3+6a

Rewrite as

7a - 3 = 3 + 6a

Evaluate the like terms

So, we have

7a - 6a = 3 + 3

This gives

a = 6

Divide through the equation by 6

so, we have the following representation

a/6 = 1

Evaluate the quotient on the right hand side

a/6 = 1

Lastly, we have

a = 6

Hence, the value of a in the equtaion is 6.
