Answer:
549
Step-by-step explanation:
A calculator can give you an equivalent expression.
I might work from the middle outward:
= 486 -3 +33×2
= 483 +66
= (480 +60) + (3 +6)
= 540 + 9
= 549
Divide 4 and 5/8 by 5/8. you will get 7 and 2/5, or 7.4. since this you need whole pieces of wood, round down to 7.
final answer=7 pieces of wood
Answer:
Step-by-step explanation:
If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:
Kyle gets the whole thing done, 100% of the way, leaving Jack lagging behind at a somewhat lower percentage of the work being done.
and cross multiply to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:
62.5x = 2000 so
x = 32%
X+y is less than or equal to 15
4x+8y is greater than or equal to 80
x is greater than 0
y is greater than 0
