Answer:
The answer is the second option or B, you have to divide the top number by the bottom number to get a unit rate.
Hi there!
So, our two equations are:
2x + 3y = 20 and
-2x + y = 4
We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.
Divide 24 by 4, which is 6.
y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1
So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16.
The solution to the system is (1,6).
I hope I helped!
Answer:
B. 23 games.
Step-by-step explanation:
Current balance: $469
Goal balance: $825.50
Profit per game: $15.50
- 825.50 - 469 = 356.50
They only need $365.50 in order to reach the goal.
- 356.50 ÷ 15.50 = 23
They need to sell 23 games, each selling for $15.50, in order to reach their goal balance, of $825.50.
- Therefore, the answer is B.
