Solve the equation for x.

8(4x + 8) = 160

a) 3
b) 7
c) 12
d) 14

Step-by-step explanation:

8(4x + 8) = 160distribute the 8 thru the parenthesis

8(4x) + 8(8) = 160

32x + 64 = 160subtract 64 from both sides

32x + 64- 64 = 160 - 64

32x = 96

x = 96/32

x = 3 <===

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.
