360 - 20 + 2x = 360
340 + 2x = 360
2x = 20
x = 10
Answer:
-4,3.5
Step-by-step explanation:
1st one
x-2x-20 = 12
-x = 32
x=-4
2nd one
-15=15q-50 - 5q
35= 10q
q = 3.5
Answer:
The correct answer is two designs are used 12 times each and other four designs are used for 13 times each.
Step-by-step explanation:
Width of the quilt Lu is making is 18 rows of 20 squares each.
Thus the perimeter of the quilt is 20 + 20 + 18 + 18 = 76.
We can also say there are 76 square as the boundary which are to be bordered with toy designs.
Each square can hold 1 design of toy and there are 6 different designs of toys.
Thus number of times each design is used
= 12
.
Thus there are two designs used 12 times each and other four designs are used for 13 times each.
