First convert the first equation to combine like terms. Then set your equations up as an addition problem. You want at least one of your variables (y) to be of opposite values so the will cancel out to leave you with just one variable (x). Plug in 1/3 for the x into one of the equations to solve for y. Then write as an ordered pair.
Vertically opposite angles are congruent to eachother so:
3Y+20=5Y-16
-5Y -20 -5Y -20
-2Y = -36
=-36/-2
Y= 18
B is the answer
Answer:
35+10 x 15 =185 that's the answer
We first determine the cost of one pair, that is:
So, each pair of shoes cost $63.Now, we determine the value of the commission:
So, the commission for each pair of shoes is $10.71, now we multiply this by 3 times. That is:
So, the commission for the three pairs of shoes will give him $32.13.
Step-by-step explanation:
the slope-intercept form =x + (y/2) =6
