Answer:
630
Step-by-step explanation:
15×2=30
40×(-15)=-600
30-(-600)=630
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
If 48 = 8 than 12 = x
to find x divide 48 by 8 which is 6. every 6 feet of fabric 1 blanket is made
so 12/6 equals 2
2 blankets can be made from 12 feet of fabric
