Answer:
25%
Step-by-step explanation:
30 is what percent of 120
Is means equals
of means multiply
30 = P * 120
Divide by 120 on each side
30/120 = P*120/120
1/4 = P
.25 = P
Now put this in percent form
.25 * 100% = P
25 % = P
Step-by-step explanation:
Let x = the number of years since the first year and let y = the total number of plants.
Roses: y = 5 + 2x
Tulips: y = 20 – 3x
You can use elimination to solve.
y = 5 + 2x
(-)y = 20 – 3x
0 = -15 + 5x
15 = 5x
3 = x
This means that 3 years after the first year, the number of rose bushes equals the number of tulip plants.
The graphs appear to
intersect at (3, 11) which verifies that x=3
The total cost of the haircut including the tip is $20.70. 18*15%=2.70+18=20.7.
