Answer from: becddjr

The first thing we need to do is distribute on the right side. 1/5 * 15 is 3, and 1/5* 5a is 1a, so now the equation is a+5 = 3+a
Subract 3 from each side and you have a+2=a
There are no solutions because any number +2 will never equal itself. This is incorrect, because the two sides are not equal to each other, so there are no solutions(:
I hope that helped(:

fabric (square meters) cloaks

7 21

4/3 4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is square meter. now we will multiply by 4 to find fabric needed for 4 cloaks.
