Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
You just have to cross multiply. 20 x 285 = 5700. 5700 / 95 = 60.
He will run 60km
Hello :
(3, 13) <span>pair - solution because when x=3 y = 5(3)-2 = 13</span>
Answer: q = 13
because p and q are inverse
=> 26/10 = q/5
⇔ q = 26/10.5
⇔ q = 13
