Answer:
the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
Amanda babysitted for 3 hours
Step-by-step explanation:
From the question, we know that:
Amanda charges $20 fee for babysitting plus an additional $5 per hour.
Let the number of hours she babysits be represented by x
This is represented by the equation:
$20 + $5× x
= 20 + 5x
We are also told:
The Wilson family paid the babysitter a total of $35 for a night of babysitting.
Hence the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
5x = 35 - 20
5x = 15
x = 15/5
x = 3 hours
Therefore, Amanda babysitted for 2 hours
Answer: Slope is -2
Step-by-step explanation:
Y² - Y¹ divide by X² - X¹
= 1 - 5 divide by 5 - 3
= -4/2
Slope is -2
If we round to the nearest hundreds, the answer would be 400. This is because 418 is closest to 400.
Answer:
plus or minus √10 / 4
Step-by-step explanation:
0=-16t^2 +10 becomes easier to solve if we rewrite it as 16t^2 = 10.
Then t^2 = 10/16 = 5/8, and t = plus or minus √(5/8), or
t = plus or minus (√5) / √8), or
t = plus or minus (√5)√8 √5*2√2
------------- = -------------------
8 8
or plus or minus √10 / 4
It would be $7.63 because you would do 42 / 5.5 and that would be sales tax. hoped this helped
