Answer:
x = 29
y = 13
Step-by-step explanation:
Write 2 equations:
x + y = 42
x - y = 16
Isolate x in the first equation:
x = 42 - y
Substitute this in for x in the second equation:
42 - y - y = 16
42 - 2y = 16
solve for y:
-2y = -26
y = 13
Plug in 13 for y in either equation:
x + 13 = 42
Solve for x:
x = 29
Answer:
54m2
Step-by-step explanation:
Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.
Taking area of first one=24m2,then area of the second =30m2.
To get area of whole shape, we add both areas=54m2
NB:Area=l×b
Answer:
1 hour
Step-by-step explanation:
Let the number of hours bowled by Isaiah and Wanda be X
Isaiah spent 16 dollars on shoe rental and 2X on bowling
Wanda spent 13 dollars on shoe rental and 5X on bowling
Since they spent the same amount, set up an equation
16+2X=13+5X
subtract 2X on either side, then subtract 13 from either side we get
3X=3
divide both sides by 3
X=1
