Answer:
C.
x=500$
y=0.2×500+300
y=100+300
y=400
I let 500$=x because they were spent by the customers
hope this helps you
have a great day :)
Answer:
Step-by-step explanation:
hello :
Y=x+8
Y=-4x-12
-4x-12 = x+8
-5x = 20
x = -4
but : y=x+8
so : y=-4+8 = 4
X + 2y = 14
-2y
x = -2y + 14
substitute x into the first equation
2 (-2y + 14) + 5y = 34
-4y + 28 + 5y = 34
simplify your y variable
y + 28 = 34
subtract 28 to find out what y equals
y = 6
now substitute y into the equation to find out what x equals
x + 2(6) = 14
x + 12 = 14
subtract 12 to get x
x = 2
now replace your values into an ordered pair, which is the solution
ANSWER: (2, 6)
Answer:
610
Step-by-step explanation:
742 is greater than 10*61, or 610. Subtract 610 from 732 first, then go on from there. (Just for fun though, the answer to 742/61 would be 12.16293442623 or 12 10/61.)

Answer: x = 29</h3>
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29
------------
Explanation:
- The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
- In the second step, I subtracted 61 from both sides to undo the "+61".
