6 times the difference of a number and 4 equals 7

Nonamiya [84]

6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6

6 ( 31/6 - 4) = 7
186/6 - 24 = 7
186/6 = 144/6 = 7

42/6 = 7
7 = 7

Each quilt requires 3 7/8 yards of fabric how many yards will you need for 1, 2, 3,4 quilts.

ICE Princess25 [194]

Step-by-step explanation:

Given,

No. of yards required for each quit = 3 7/8

can also be written as = 59/8

so,

yards,

required for 2 quilts = 2 × 59/8 = 14 3/4

required for 3 quilts = 3 × 59/8 = 23 4/8

required for 4 quilts = 4 × 59/8 = 8 1/2
