A) The initial value is $55. Lenny bought a soda on each day for a week. so,
$55-1.75(7)=x
b) $11,000-850(12). $11,000 is the initial value and it costs $850 each month. Mandy pays for 12 months. So we multiply the cost of one month by 12 and subtract that cost from the total amount of money.
c)$8.45-0.25(18)
Slope is -1
Y intercept is 2
Answer: x=6
Step-by-step explanation:
1) add 1/8 to both sides
2) divide both sides by 1/4
3) 1.5/.25= 6
Answer:
An octagon has eight interior angles.
Interior angle total sum = (n-2) x 180, where n = number of sides.
Since an octagon has 8 sides, we have:
6 x 180 / 8, which is 135.
The answer is 135.

Answer:
5 hours
Step-by-step explanation:
Scott's delivery rate = 10 pizzas per hour
Kenneth's delivery rate = 12 pizzas per hour
Combined delivery rate
= Scotts delivery rate + Kenneth's delivery rate
= 10 + 12
= 22 pizza's per hour (take reciprocal to find the rate in "hours per pizza")
= 1/22 hours per pizza
Given that they both deliver 110 pizzas combined, the will take
= 1/22 hours per pizza x 110 pizzas
= (1/22) x 110
= 5 hours
