Answer from: Quest

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.

Answer from: Quest

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
