Answer:
64 pies sold
Step-by-step explanation:
x = number of cakes sold
y = number of pies sold
Last weekend the bakery sold 118 total items
x + y = 118
Last weekend the bakery earned $1,932.
18x + 15y = 1,932.
Get rid of one of the terms, in this case x.
x + y = 118 becomes
18x + 18y = 2124
Subtract the equations from each other
(18x - 18x) + (18y - 15y) = 2124 - 1932
3y = 192
y = 64
Subsititue y into the orginal qeuation to solve for x and check it's right.
x + 64 = 118
x = 118 - 64 = 54
18(54) + 15(64) = 1932
Answer:
6^2
Step-by-step explanation:
It is written as a division problem. When dividing exponents with the same base you subtract the exponents. in this class, 7-5=2. So now you write the new exponent:
Answer:
(-6, 9) is the solution set for given system.
Step-by-step explanation:
Given that:
3x-y=-27 ----------- eq1
4x+2y=-6 --------- eq2
Solving by combining the equations:
Dividing eq2 by 2 we get:
2x + y = -3 ------- eq3
Now add eq1 and eq3, we get:
5x = -30 (y from both equations will be cancelled out)
Dividing both sides by 5:
x = -6
Now putting value of x back in eq3:
2(-6) + y = -3
-12 + y = -3
Adding 12 on both sides:
y = -3 + 12
y = 9
So the solution set for given system is (-6, 9)

Total number of hours = 15
Let the hours spent tutoring french be x.
Therefore hours spent on scooping ice cream = (15 - x)
Amount: Tutoring french is $15 an hour, total for x hours = 15x
For scooping ice cream it is $10 an hour 10*(15 - x) = 150 - 10x
To make more than $180
15x + (150 - 10x) > 180
15x + 150 - 10x > 180
15x - 10x > 180 - 150
5x > 30
x > 30/5
