A dressmaker needs to cut 18-inch pieces of ribbon from rolls of ribbon that are 12 feet in length. How many 18-inch pieces can the dressmaker cut from
10 of these rolls of ribbon?

80 pieces

Step-by-step explanation:

12 ft x 12 in = 144 inches

144 in x 10 rolls = 1,440 inches

1,440 in / 18 in = 80 pieces of ribbons

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: just subtact the units and then add the non negative : happy to
