Answer:
Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.
Since Claire is working two summer jobs, making $ 7 per hour washing cars and making $ 15 per hour clearing tables, and in a given week, she can work at most 9 total hours and must earn a minimum of $ 90, to determine one possible solution the following calculation must be performed:
15 x 9 = 135
135 - 90 = 45
45/7 = 6.42
6 x 7 + 3 x 15 = 42 + 45 = 87
5 x 7 + 4 x 15 = 35 + 60 = 95
Therefore, at a minimum, Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.
I would say its the second one.
the student shouldve distributed the 2^3x+3 into 2^3x+9
Step-by-step explanation:
x+y=17 (First equation)
x-y=3 (Second equation)
Solving Equation (i)
x+y=17
x=17-y(First equation)
Putting value of x in equation (ii)
x-y=3
x=3+y
17-y=3+y
17=3+y+y
17=3+2y
2y=17-3
y=14/2
y=7
Putting value of y in equation(i)
x=17-y
x=17-7
x=10
