Answer:
Step-by-step explanation:
We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :
Remove the parenthesis to make it easier to read :
Multiply the numerators :
Multiply the denominators :
Apply the negative rule :
Cancel the common factor which is 18 :
Apply the addition exponent rule :
Subtract :
Apply the rule for y :
Subtract :
Cancel the common factor of z^3 :
So you would subtract 0.32 from 1.16 because it is the initial amount. Then divide what you get from that (0.84) by .21. You're gonna get .04- but that's not the answer because you have to add the initial ounce that is worth $0.32. So The answer is B
3.50x + 5.50x + 6 = 51
# 10
9x + 6 = 51
Subtract 6 from both sides
9x = 45
Divide both sides by 9
x = 5
#11
5x - 18 - 4x = -36
x -18 = -36
Add 18 to both sides
x = - 18
