Answer:
7
Step-by-step explanation:
Let's say the customer has x items. For each item, we add 2 seconds. For 3 items, we need 2 + 2 + 2 = 2*3 seconds. For x items, we need 2 * x seconds. Then, we add the processing payment time of 30 seconds, so for x items, the total amount of time = 30 + 2 * x
Here, the total amount of time is 44, so we have
44 = 30 + 2x
subtract 30 from both sides to isolate the variable and its coefficient
14 = 2x
divide both sides by 2 to isolate x
x = 7
Answer:
41
Step-by-step explanation:
Substitute x = 3 into g(x) then substitute the value obtained into g(x)
g(- 3) = (- 3)² - 2(- 3) - 7 = 9 + 6 - 7 = 8
g(8) = 8² - 2(8) - 7 = 64 - 16 - 7 = 41
Answer:

Step-by-step explanation:
Distance
Time
Average speed
- d/t = 18.2 ÷ 14/60 = 182/10 × 60/14 = 78 mph
The difference with allowed speed
Answer:
5+2=7
6+180=186
186+7=193
the answer is 193m
