solve each system by substitution
1/2x+1/3y=6
x-y==2
Step-by-step explanation:
First, let's rewrite the equations.
1/2x + 1/3y =6
x - y = 2
The easiest system to use for substitution is the second one. Let's solve for X.
x - y = 2
add y to both sides!
x = 2 + y
Now that we know x = 2 + y we can use it to substitute in the first equation.
1/2(2 + y) +1/3y = 6
1 + 1/2y +1/3y = 6
5/6y = 5
y = 36/5

Mrs. Vega assigned her students a book report about the most recent novel discussed in class. The following dot plot displays the number of pages written by the students in her first-period class. What percent of Mrs. Vega's class wrote a 4 page book report? 3% 12% 30% 33.13%
(She has 18 students and 6 students wrote 4 pages)
Answer:
33 1/3%
Step-by-step explanation:
Explained in question comments :)
The percent of Mrs. Vega's class who wrote a 4 page book report is 33 1/3 %.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given a dot plot which shows the number of pages written by the students in her first-period class.
Total number of students in Mrs. Vega's class = 18
[Total number of students is the number of dots in the dot plot]
Number of students who wrote 4 pages = number of dots above 4 = 6
Percentage of students who wrote 4 pages = 6/18
= 0.333
= 33.3%
= 33 1/3 %
Hence the required percent is 33 1/3 %.

Answer:
[tex]Rate = 6[/tex]
[tex]Rate = 10[/tex]
[tex]Rate = 18[/tex]
[tex]Rate = 162[/tex]
Step-by-step explanation:
Given
See attachment for table
Solving (a): Rate of change between 2nd and 3rd point on A
The rate of change is calculated as:
[tex]Rate = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In table A, the 2nd and 3rd point is:
[tex](x_1,y_1) =(1,7)[/tex]
[tex](x_2,y_2) =(2,13)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{13 - 7}{2 - 1}[/tex]
[tex]Rate = \frac{6}{1}[/tex]
[tex]Rate = 6[/tex]
Solving (b): Rate of change between 3rd and 4th point on A
In table A, the 3rd and 4th point is:
[tex](x_1,y_1) =(2,13)[/tex]
[tex](x_2,y_2) =(3,23)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{23 - 13}{3 - 2}[/tex]
[tex]Rate = \frac{10}{1}[/tex]
[tex]Rate = 10[/tex]
Solving (c): Rate of change between 2nd and 3rd point on B
In table B, the 2nd and 3rd point is:
[tex](x_1,y_1) =(2,11)[/tex]
[tex](x_2,y_2) =(3,29)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{29 - 11}{3 - 2}[/tex]
[tex]Rate = \frac{18}{1}[/tex]
[tex]Rate = 18[/tex]
Solving (d): Rate of change between 4th and 5th point on B
In table B, the 4th and 5th point is:
[tex](x_1,y_1) =(4,83)[/tex]
[tex](x_2,y_2) =(5,245)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{245 - 83}{5 - 4}[/tex]
[tex]Rate = \frac{162}{1}[/tex]
[tex]Rate = 162[/tex]

John is placing cement tiles for a patio in a rectangle surrounding a
rectangular fire pit. The fire pit has a width of x ft and a length that is 4
times the width. The entire patio is 9 ft wider and 13 ft longer than the fire
pit. What is the area that he will need to buy tiles for?
Answer:
31x + 55 sq. ft.
Step-by-step explanation:
Width of Fire Pit = x ft. Length of Fire Pit = 4x ft.
Width of Patio = x + 5 ft. Length of Patio = 4x + 11 ft. Area of Fire pit = 4x * x = 4x² sq, ft.
Total Area of Rectangular Patio (including Fire pit) = (4x + 11)(x+5)
= 4x² + 31x + 55 sq. ft.
Area for which tiling is done = Area of Rectangular patio - Area of fire pit
= 4x² + 31x + 55 - 4x²
= 31x + 55 sq. ft.

On a recent survey, 40% of the 900 people surveyed preferred running.
How many people preferred running?
Answer: 550
Explanation:
Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)
So 900-360
Answer:
360
Step-by-step explanation:
So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.
Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.
And you can check it by multiplying 900 x .40 which would be 360
Hope this helped, good luck :)
