9x + y = 7
y = 9x + 7
6 = 9(5) + 7
6 = 45 + 7
<u>6</u> = <u>52</u>

Answer:
x^15
Step-by-step explanation:
x^3 * x^2 (x^3)^2 x^6
-------------------------------
x^2
First I will use the power of powers x^a^b = x^(a*b)
x^3 * x^2 x^(3*2) x^6
-------------------------------
x^2
x^3 * x^2 x^(6) x^6
-------------------------------
x^2
Next we will use the multiplication rule x^a * x^b = x^(a+b)
x^(3 +2+6+6)
-------------------------------
x^2
x^(17)
-------------------------------
x^2
Next we will use quotient rule x^a / x^b = x^(a-b)
x^(17 -2)
x^15
Answer:
She spent 5 hours mowing lawns.
Step-by-step explanation:
To solve, we will just use some algebra
8h + 20 = 60 | Subtract 20 from both sides
8h = 40 | Divide both sides by 8
h = 5
We can confirm this by plugging it back into the original formula.
8(5) + 20 = 60
40 + 20 = 60
60 = 60
Answer:
The solution is x = 9, y = -1.
Step-by-step explanation:
x + y = 8
x - y = 10 Adding to eliminate y:
2x + 0 = 18
x = 9 Substituting x = 9 into the first equation:
9 + y = 8
y = 8 - 9
y = -1..
