Petra is 13 and her mother is 32. I used this equation:
$p + 2p + 6 = 45$
if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.

Solve the system by substitution.<br> 4y =<br> 5x -10y =-50

Trava [24]

Answer:

$x = -20 ; y =-5$

Step-by-step explanation:

Eqn. 1 ----> 4y = x

Eqn. 2 ----> 5x-10y = -50

(Simplifying eqn.2 further)

$=>5(x-2y)=-50$

$=>x-2y=\frac{-50}{5} =-10$

(Substituting the value of x from eqn. 1)

$=>4y-2y=-10$

$=>2y=-10$

$=>y =\frac{-10}{2} =-5$

Now, substituting the value of y in eqn. 1 ,

$x = 4*(-5)=-20$

I believe that you are doing multiplication with this.

So… 9 x 3.65 = 32.85

Hope this helps. :)
