Answer:
18
Step-by-step explanation:
16 × 9 = 8 × x
x = 18
4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.
with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x
without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x

Answer:
The first answer choice, 4632.5
Step-by-step explanation:
At the rate of 85 feet per hour, after 5.5 hours the apprentice would have covered 467.5 square feet. Subtracting this from the total amount of 5,100 square feet, you get 4632.5, or the first answer choice. Hope this helps!
Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)
