Find the x- and y-intercepts of the graph of 3x + 2y = 20. State your answers as
whole numbers or as improper fractions in simplest form.
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10
What are coordinates in a graph?
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
3x + 2y = 20
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
Now,
3x + 2y = 20
Putting x = 0 in (1) we get the y-intercept.
3x + 2y = 20
3x0 + 2y = 20
0 + 2y = 20
2y = 20
Divide both sides by 2.
y = 20/2
y = 10
Putting y = 0 in (1) we get the x-intercept.
3x + 2y = 20
3x + 2 x 0 = 20
3x + 0 = 20
3x = 20
Divide both sides by 3.
x = 20/3
Thus,
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10

At a school bake sale, all of the pies were cut into 6 pieces, so each person who bought a piece got ⅙ of a pie. Each slice sold for $2. The were sold out. How much money did the kids make if there were 11 pies sold? B. How many slices were sold?
Answer:
They made 132$, and 66 slices were sold.
Step-by-step explanation:
If all of the pies were cut into six pieces, and each piece costed $2, then you can multiply 6 x 2 to determine how much each pie cost. ($12)
If each pie costed $12 and there were 11 pies sold in total, then you can multiply 12 x 11 to find out how much money they made.
And to find out how many slices they sold you just have to multiply the 11 total pies by 6 because each pie had six pieces.

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
Answer:
Distance cover by Alyson = 16 miles
Step-by-step explanation:
Given:
Distance cover together = 39 miles
Assume;
Distance cover by Jeff = a
Distance cover by Alyson = a - 7
Find:
Distance cover by Alyson
Computation:
a + (a - 7) = 39
2a - 7 = 39
2a = 46
a = 23
Distance cover by Alyson = a - 7
Distance cover by Alyson = 23 - 7
Distance cover by Alyson = 16 miles

Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50

A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The volume of the prism is 51 cubic centimeters. What is the height of the tubing?
Answer: 17 cm
Step-by-step explanation:
For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:
V = B*H
Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3
Then:
B = 3cm^2
V = 51cm^3
If we replace those in the equation above, we get:
51 cm^3 = (3cm^2)*H
Solving this for H gives:
(51 cm^3)/(3 cm^2) = H = 17 cm
The height of the tubing is 17 cm
