Answer:
x = 11
Step-by-step explanation:
x + (x - 2) = 20
2x - 2 = 20
2x - 2 + 2 = 22 + 2
2x = 22
x = 11
You- y=50+20x
friend y=30+20x
If you subtract, the difference is only 20 dollars at any given months since the rates are the same
Answer:
Step-by-step explanation:
Given
Height H = 4 feet
Velocity = 14ft/s
Required
Time the pumpkin will hit the ground
Using the equation of mottion
H = ut + 1/2gt²
4 = 14t + 1/2(9.8)t²
4 = 14t + 4.9t²
4.9t²+14t-4 = 0
t = -14±√196+16(4.9)/2(4.9)
t = -14±√196+78.4/2(4.9)
t = -14±16.57/9.8
t = -14+16.57/9.8
t = 2.57/9.8
t = 0.2seconds
Answer:
2 50 mL bottles
Step-by-step explanation:
Find the cost per mL
55 / 80 mL =.6875 per mL
Now find the price of the buy one get one 1/2 off
45 + 1/2 (45) = 45+22.5=67.5
That will be for 50+50 mL
67.5 /100 ml =.675 per mL
The 100 mL is a better deal
