The incorrect inequality is g > 80. The symbol ">" means greater than. So g > 80 would translate to meaning Kyle's grandmother is greater than 80. However, the problem states that his grandmother is not more than 80, meaning she is either 80 or younger. So the inequality should be g ≤ 80, or Kyle's grandmother is less than or equal to 80 years of age.
By definition, we have the following equation:
d = v * t
Where,
d = Distance
v = rate
t = time
The total distance traveled will be:
45t + 60 (8 - t) = 405
Solving for the time we have:
t = 5 s
Answer:
he drives at 45 mph for 5 s
T=-0.0035a + g
-65.5 = - 0.0035a + 57
-57 = - 0.0035a
-122.5 = 0.0035a
-122.5/0.0035 = a
a = 35,000
Answer: I do not know what she is paid per hour so I cannot solve this for you. You can figure this out on your own by multiplying the amount she get paid per hour by 7 to get the correct amount. If you are unable to do this by hand, use a calculator or look it up on google.
Hope this helps! :)
