Answer: $4.50
Step-by-step explanation:
If she spent 10.50, and had 7.50 left, her total was 18.
$18/4=$4.50
Theoretically, the answer is infinity. however, in a non perfect universe such as our own, practically the answer would be around 17ft.
Answer:
2y = 3x - 8
y = 3/2x - 4
Work
-2x + 5(3/2x - 4) = -9
-2x + 15/2x - 20 (+20) = -9 (+20)
-4/2x + 15/2x = 11
11/2x * (2/11) = 11 (2/11)
x = 2
3(2) - 2y = 8
6 (-6) - 2y = 8 (-6)
-2y = 2
y = - 1
final answer:
x = 2
y = -1
There are 3, quadrilaterals, pentagons and hexagons
