Answer:
D
Step-by-step explanation:
given the 2 equations
x + 2y = 27 → (1)
2x + 3y = 46 → (2)
Rearrange (1) expressing x in terms of y by subtracting 2y from both sides
x = 27 - 2y ← substitute into (2)
2(27 - 2y) + 3y = 46
54 - 4y + 3y = 46
54 - y = 46 ( subtract 54 from both sides )
- y = - 8 ( multiply both sides by - 1 )
y = 8 → D
$20 per n games
When n = 6
20(6) = 120
Jason will earn $120 for refereeing 6 games.
12/(5+10)=m/10
4/5=m/10
m=8
The formula for the area of a rectangle is (length x width)
so, 9 x ? = 36 which can also be written as 36 ÷ 9 = ?
and (36 ÷ 9 = 4)
Length x Width = Area
9 cm x 4 cm = 36 cm²
