Answer:
is the system of equations representing the situation.
Step-by-step explanation:
Given:
Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.
Now, to find the system of equations representing the situation.
<u><em>Let the number of haircuts be </em></u><u><em /></u>
<u><em>Let the number of hair dyes be </em></u><u><em /></u>
So, Alexandra can give 3 haircuts and 2 hair dyes in:
Now, giving 2 haircuts and 4 hair dyes in:
Therefore,
is the system of equations representing the situation.
Answer:
No, Jason did not solve correctly
Step-by-step explanation:
Jason has saved 41% of what he needs to buy a 73$ skateboard.
Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Let compare both statements
50% of 70 = 70 ÷ 0.5 (140)
50% × 70 = 140
50/100 × 70 = 140
35 ≠ 140
JASON DID NOT SOLVE CORRECTLY
This is because the left-hand side used the operation of multiplication while the right-hand side used the operation of division.
Answer:
Step-by-step explanation:
Every 10 hours that go up means the salary goes up by $100
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Initial investment= $8,800
Percentage decrease= 26.5%
<u>To calculate the money Maya lost, we need to use the following formula:</u>
Decrease on dollars= 8,800*0.265
Decrease in dollars= $2,332
<u>At the end of the years she has:</u>
Money left= 8,800 - 2,332
Money left= $6,468
