Answer:
28 hours
Step-by-step explanation:
Adena, Julius, and Tia volunteered to read to children at the public library.
Let us represent, the number of hours worked by
Adena = x
Julius = y
Tia = z
Julius worked two hours less than Tia.
y = z - 2
z = y + 2
Adena worked twice as many hours as Julius.
x = 2y
Altogether they worked 58 hours.
x + y + z = 58.... Equation 1
We substitute 2y for x and y + 2 for z in Equation 1
2y + y + y + 2 = 58
4y + 2 = 58
Collect like terms
4y = 58 - 2
4y = 56
y = 56/4
y = 14
We are the find the number of hours Adena worked which is represented by x
Note that:
x = 2y
y = 14, hence,
x = 2 × 14
x = 28 hours
Therefore, the number of hours Adena worked is 28 hours
I believe its 50 because 0.35x50=17.5 (35%=0.35)
Answer:
10 is equal or less than (sign that opens up to the right with line underneath) j+5
Answer:
$2 will be your answer
Step-by-step explanation:
If u start with the 85, then add 73 it will add up to $1.58 meaning that since it is above $1.49 you will round up to $2
And both of them indivisually will equal $1 each rounded up
