Answer:
36
Step-by-step explanation:
Divide 108 by 3 to get your answer, since the denomintors are the same.
103/3 = 36
⎧ y=2x+3 y=−3x+3
pratctice and Solving Solve each equation with variables on both sides 1. 6x - 2 = x + 13
Answer:
x=3
Step-by-step explanation:
6x - 2 = x + 13
subtract 1x from both sides
5x - 2 = 13
isolate the 5x by adding 2 to both sides
5x = 15
finnaly devide both by 5

1-Describe the error in the way the calculation of the slope of the two points is set up and/or solved. Please be specific. Do not just state what the slope should be. Describe the error.
2- Use the same two points from the error analysis question above and show how to calculate the slope correctly. Then, use the correct slope and one of the points to write the equation in point-slope form of the line. Show all work!
Answer:
Please check explanations for answer
Step-by-step explanation:
Let’s have two points (5,10) and (15,20)
1. Let’s find the slope of these two points
Mathematically, the slope can be calculated using the formula;
m = (y2-y1)/(x1-x2)
So m = (20-10)/(5-15) = 10/-10 = -1
The error here is the formula used in calculating the slope
The formula should be;
m = (y2-y1)/(x2-x1) and not x1-x2
2. To calculate the slope correctly, we have;
m = (y2-y1)/(x2-x1)
So the slope will be;
m = (20-10)/(15-5) = 10/10 = 1
In the point slope form, the equation can be represented as;
y-y1 = m(x-x1)
Let’s use the point (5,10)
y- 10 = 1(x-5)
The above is the point slope form
using one of the points and the correct slope of the line
A round plate has a radius of 8.25 inches. What is the circumference of the plate?
Answer: The circumference of the plate = 51.86 inches.
Step-by-step explanation:
Given : The radius of a round plate = 8.25 inches
Formula: circumference of a circle = [tex]2\pi r[/tex] , where r = radius of circle .
Then, the circumference of the plate [tex]=2\times\dfrac{22}{7}\times8.25[/tex] [ [tex]\pi=\dfrac{22}{7}[/tex] ]
[tex]=51.857142857\approx51.86\ \text{inches}[/tex]
Hence, the circumference of the plate = 51.86 inches.

While on vcacation, kevin and his family visit mount rushmore in south dakota. They watcha movie in the vistor center for 1/2 of an hour. This accounta for 1/4 og the toatl time the spend at mount rushmore. What equation can you use to find the total amount of time t kevin's family spends at mount rushmore
Answer:
t = 1/2 ÷ 1/4
t = 2 hours
Step-by-step explanation:
Time spent watching movies = 1/2 of an hour
This accounts for 1/4 of the total time thei spend at mount rushmore.
1/2 = 1/4t
Where t = total time they spent at mount rushmore (hours)
1/2 = 1/4t
Determine the equation to find t
t = 1/2 ÷ 1/4
= 1/2 × 4/1
= 4 / 2
= 2
t = 2 hours

An eight ft board is cut into two pieces. One piece is 2 ft longer thant he other. How long are the pieces?
Answer: 6 ft and 2 ft
Step-by-step explanation:
Answer:
6ft and 2ft
Step-by-step explanation:
8ft board ÷ 2 pieces = 4ft each
4ft and 4ft boards. But one of them is longer by 2ft so:
4ft - 2ft = 2ft
4ft + 2 ft = 6ft
So, one piece is 2ft and the other piece is 6ft

A clothes hanger is in the shape on an isosceles triangle. If the hanger is 70° wide what are the base angles?
Answer:
55°
Step-by-step explanation:
Given parameters:
Angles in the triangle;
70°, X° and X°
The triangle is an isosceles triangle;
In all triangles, the sum of the interior angles is 180°
So;
70° + X° + X° = 180°
70° + 2X° = 180°
2X° = 180° - 70°
2X° = 110°
X° = [tex]\frac{110}{2}[/tex] = 55°

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month? Explain how you found your answer.
Answer:
Made $840 in commissions for the past month.
Step-by-step explanation:
sales = 70 * 150 = 10500
commission = .08 * 10500 = 840
Answer:
$840
Step-by-step explanation:
8% = 0.08
.08 * 150 = 12 per unit sold
12 * 70 = 840.00

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches
Answer: 10 inches
Step-by-step explanation:
1. multiply 14 by 2 to get 28.
2. Subtract 28 from 48 to get 20
3. Divide 20 by 2 to get 10
your answer is 10
Answer: 10 inches
Step-by-step explanation:
a worksheet is usually a rectangle
the formula for the perimeter of a rectangle is 2x + 2y
Lets say that x = the length and y = the height
it already gives you x = 14, so plug everything in to find y
P = 2x + 2y
48 = 2(14) + 2y
48 = 28 + 2y plug in x = 14 and multiply
20 = 2y subtract 28 from both sides to get this
y = 10 then divide both sides by 2 to get the answer

writing equations of lines
Step-by-step explanation:
Equation of straight line is y=mx+c
choose any two points on straight line
for me I choose:(-3,11) and (3,-1)
use these two points to find gradient,m.
m= (-1-11)/(3-(-3))
m= -2
now, y=-2x+c
choose any point on the straight line
I choose point (3,-1)
sub the point into the equation to find c
-1=-2(3)+c
c=5
equation: y=-2x+5
