Answer:
6
Step-by-step explanation:
-X+11=-2X-7
11=3X-7
18=3X
18/3= 6
You can multiply the top equation by 3 and the bottom equation by 2, so you get:
-6y = 42
+6y = 18
(You also multiply whatever is in front but it's cut off so...)
Then you can add the equations so you get:
(whatever numbers cut off are) = 60
Then you solve for the variable cut off and sub it into one of the equations and solve for y.
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%
