Answer:
Step-by-step explanation:
17(7x−3) =1
Divide both sides by 17
7x - 3 = 1/17
Collect like terms
7x = 1/17 + 3
x = (1/17 + 3) /7
x = 52/17 ÷ 7
x = 52/17 × 1/7
x = 52/119
Each week the cookies sales was Aprox 167. Each week the car wash profit was about 175
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
3xy + 10xy - 5x + 2x - 2yx
Add 3xy to 10xy
13xy - 5x + 2x - 2yx
Add -5x to 2x
Final Answer: B.) 13xy -3x - 2yx
