X=t-yz and we are asked to solve for y so, subtract t from both sides
x-t=-yz divide both sides by -z
(x-t)/(-z)=y
y=(x-t)/(-z) multiply the numerator and denominator by -1
y=(t-x)/z
Answer:
Step-by-step explanation:
20% discount is 1/5 x 68 = 13.60
So pre-tax price is 68 - 13.60 = 54.40
Add sales tax:
54.40 x 1.06 = 57.66
so the answer is C
Answer:
A.
If the depth is 8 feet, the area of the base is 300 square feet. And if the area of the base is 600 square feet, the depth of the water is 4 feet.
Step-by-step explanation:
Depth = Volume/Area
d = V/A
12 = V/200
V = 12 × 200
= 2,400
When d = 8, A = 300
V = dA
= 8 × 300
= 2,400
When d = 4, A = 600
V = 4 × 600
= 2,400.
The first option is correct.
Answer:
324
Step-by-step explanation:
you would multiply 27 × 12 and that would equal 324
Answer:
6 years
Step-by-step explanation:
Convert feet to inches: 3 feet = 36 inches, 7 feet = 84 inches
Set two equations equal to each other:
First equation, Type A has a slope of 12 (grows 12 inches per year) and a y-intercept of 36 (it starts 36 inches (or 3 feet) tall)
Second equation, Type B has a slope of 4 (grows 4 inches per year) and a y-intercept of 84 (starts at 84 inches (or 7 feet) tall)
12x + 36 = 4x + 84
subtract 36 from both sides
12x = 4x + 48
subtract 4x from both sides
8x = 48
divide by 8 on both sides
x = 6
It will take the tree types 6 years to be the same height
Hope that helps!
