Answer:
x = 200
Step-by-step explanation:
Plug in 15 as y into the equation and solve for x:
1/5x - 2/3y = 30
1/5x - 2/3(15) = 30
1/5x - 10 = 30
1/5x = 40
x = 200
So, when y = 15, x = 200
7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10
Now combine like terms.
19b - 66 = 10
Add 66 to both sides.
19b = 76
Divide both sides by 19.
b = 4
The answer is b = 4.
Answer:
c= 66
Step-by-step explanation:
2c/15(15)=8.8(15)
2\2c=132/2
c= 66
A. If it has a 60% mark up price of $120 that would be $60 so the total would be $180. B. If there selling the bike at what the store is selling it for it would be $126 because 30% of $180 is $54 so subtract $54 from $180 and you will get $126 C. The store would make a total profit of $6.
