2×5=10
3×4=12
10+10+12+12=44 inches
you add 10 and 12 twice because you have to account for the top and bottom of the piece of wrapping paper as well as the left and right sides of it
Answer:
x = 74
y = 37
z = 25
Step-by-step explanation:
x -- 180-106=74
y -- 74/2=37
z -- 4z+6=106
subtract 6 from both sides 6-6=0, 106-6=100
4z=100
divide by 4 on both sides 4z/4=1z, 100/4=25
Answer:
-4n^4-4n^2-8n+3
Step-by-step explanation:
you combine the like terms
For every 1/4 metric ton it takes 1/8 hours
then multipling by 8 to make the hours =1
for every 2 metric tons it take 1 hour
so the quotient is 2 metric tons per 1 hour
