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

the first one hunz
Step-by-step explanation:
it can be used to calculate the length of a circular bracelet
The mass of the elephant in grams is 7,100,000.
Explanation:
There are 1000 grams in one kilogram. To find out how many grams are in 7100 kilograms, we multiply 1000 and 7100 to get 7,100,000. Therefore, the answer is 7,100,000 grams.
The two shortest sides have to add up to be bigger than the longest side.
A. 17,12,6 6+12= 18 18>17 <- this is a triangle
B. 25,13,38 25+13= 38 38=38 <- this is NOT a triangle
C. 14,27,36 14+27= 41 41>36 <- this is a triangle
D. 39,44,6= 39+6= 45 45>44 <- this is a triangle
The answer is B. <em>
