Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
8-5=3 is the remaining half
weekly allowance=2(1÷2) where (1÷2) is 3
2×3=6
The weekly allowance should be 6.
Answer:
The sale price would be $102.50
Step-by-step explanation:
To find this amount, start by multiplying the price by the sale percentage,
$150 * 35% = $47.50
Now subtract that amount from the original.
$150 - $47.50 = $102.50
Next term will be 100
as series is 18²,16²,14²,12² so next will be 10²
hope it helps
