Answer:
LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18
Step-by-step explanation:
9 = 32
-1 = -1
-1 = -1
+2 = 2
+2 = 2
+2 = 2
LCM = 2×3^2 = 18
18 / 9 = 2
18 / -1 = -18
18 / -1 = -18
18 / +2 = 9
18 / +2 = 9
18 / +2 = 9
So paid160
75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost
Assume that only the four 9 ft by 9 ft walls are to be papered. Each wall will require (9 ft)^2 sq ft of paper, or 81 sq ft of paper. Multiply that by 4 (since there are four walls): 324 sq ft. Now subtract 93 sq ft from 324 sq ft to obtain the answer to this problem.
