OR
50/2=25
Step-by-step explanation:
If Paul has made 50 cupcakes so far, that means he's been baking for two hours.

50 in total
50/2=25
25*2=50
Answer:
the answer is 9x
Step-by-step explanation:
For the same reasons as the last problem...
s(n)=20(1-(1/2)^n)/(1-1/2)
s(n)=40(1-(1/2)^n)
But this time we are not starting at one so we must subtract the sum of s(2) from the sum of s(12) so:
40((1-(1/2)^12-(1-(1/2)^2)
40(0.249755859375)
≈9.99 (to nearest one-thousandth)

Step-by-step explanation:
<u>Line A</u>
gradient = 4
x-intercept = -1
y-intercept = 4
<u>Line B</u>
gradient = -3
x-intercept = -1
y-intercept = -3
<u>y + 8x = - 72</u>
x-intercept = -9
y-intercept = -72
