There are two approaches to solving the equation -3x + 10 = 4x - 20
Subtract 4x from both sides. OR Add 3x to both sides.
–7x + 10 = –20 OR 10 = 7x – 20
Solve the equation using both approaches.

Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8
Answer:
D
Step-by-step explanation:
Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.
The total number of marbles in the bag could be (d) 8
How to determine the possible total?We have:
Blue proportion = 3/4
This means that the green proportion is
Green proportion = 1 - 3/4
Evaluate
Green proportion = 1/4
Express as ratio
Blue: Green = 3/4 : 1/4
Simplify
Blue: Green = 3 : 1
Add the ratios
Total = 3 + 1
Total = 4
The above means that the total number of marbles in the bag is a multiple of 4
i.e. 4, 8, 12, 16, 20......
Hence, the total number of marbles in the bag could be (d) 8

The table represents a linear function. What is the slope of the function? O -10 16 O5 O5 O10 24
Answer: 5
Step-by-step explanation:
I got it right on the test.
The slope of the function is 5.
The correct option is C.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We can take two points from the table as (-4, -16) and (-2, -6).
So, slope of the function is
= (-6 - (-16))/ (-2 - (-4))
= (-6 + 16)/ (-2 +4)
= 10 /2
= 5
Thus, the required slope is 5.

Y=Mx+b
Step 1: Flip the equation.
Mx+b=y
Step 2: Add -mx to both sides.
B=-mx +y
lol I can’t be bothered to solve for m so here’s the answer
solve for M vv
M= -b+y / x -b+y are the numerators and x is the denominator

Line ST and point V are shown on the graph. Line WW is to be drawn on the graph such that it is perpendicular to line ST. If the coordinates of point Ware (-1, y), what is the value of y?
-5
2
3
-7
Answer:
3
Step-by-step explanation:
We can use the formula of slope to find this answer.
The formula to find the slope is y2-y1/x2-x1.
The slope of line ST is 1/5: 2-0/5-(-5); 2/10=1/5
We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.
Therefore, the perpendicular line should have a slope of: 1/5------>-5
To find which answer it is, follow the steps below:
y2-y1/x2-x1
plugin known values
-2-y1/0-(-1)
-2-y1/1
In order to make this -5, y1 needs to be 3
-2-3/1=-5
3 is the correct value
The value of y is 3.
What is slope?The slope of a line is a measure of its steepness.
Given:
Ware( -1, y)
Now,
slope of line ST =2-0/5-(-5)
slope=1/5
As two lines to be perpendicular, they have to have reciprocal opposite slopes.
Thus, the perpendicular line slope =-5
Now, y2-y1/x2-x1
= -2-y1/0-(-1)
= -2-y1/1
= -2-3/1
=-5
hence, the value of y is 3.

A college accepted new applicants, of whom 56% were male and 44% were female. The board of directors was not pleased that males were being accepted at a greater percentage than females. A private company investigated and found each department accepted a greater percentage of females over males. What may make this claim possible?
Answer:
Simson paradox
Step-by-step explanation:
In Simpson paradox, the trend that appears in the combined data reverses or disappears in the results of the several individual groups that make up the combined data
In the question, given that the percentage of female applicants accepted = 44% while the percentage of male applicants = 56%, and that the private company found that each department accepted a greater percentage of females over males
The above claim can occur when there is a confounding variable, which is the number of applications from female or male
The percentage used or the data provided to by the private company in each department are percentage in proportion of number of accepted females to total number of female applicants and percentage in proportion of number of accepted males to total number of male applicants, whereby, when there are fewer number of female applicants to each department and more were accepted, their percentage will be larger than the percentage of the male applications that have a lower percentage but larger number of applications, such that the accepted male applicants still outnumber the female when that total number of applications are considered.

1. A hexagon is inscribed in a circle. If the difference between the area of the circle and the area
of the hexagon is 24 m”, use the formula for the area of a sector to approximate the radius
of the circle. Give an exact answer( doesn't have to be rationalized) and round to 2 decimals.
Answer:
The radius, r ≈ 6.55 m
Step-by-step explanation:
The given parameters are;
An inscribed hexagon in a circle
The area of the hexagon = Area of the circle - 24 m²
The formula for the area of the circle = π·r² = π × r²
The area of each of the six equilateral triangle in the hexagon = √3/4 × r²
Where;
r = The radius of the circle
The area of a sector of a circle in which the equilateral triangle is inscribed = 60/360×π·r² = 1/6×π·r² = 1/6 × Area of the circle
Given that the sector of the circle in which one of the six equilateral triangles of the hexagon is inscribed is 1/6 the area of the circle, the difference in area between the equilateral triangle and the sector = 24/6 = 4
Therefore, the difference in the area between the sector of the circle and the area of the equilateral triangle = 4 m²
We then write; 1/6×π·r²- √3/4 × r² = 4
r²·(1/6×π- √3/4) = 4
r² = 4/(1/6 ×π - √3/4) = 48/(2·π -3·√3)
r = √(48/(2·π -3·√3) = 6.55 m to 2 decimal places
The radius, r ≈ 6.55 m.

On average, Ethan drinks 3/4 of an 10 ounce glass of water in 2 minutes how many glasses of water does he drink in one hour
Answer:
22.5 glasses of water
Step-by-step explanation:
Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.

Answer:
Option (A)
Step-by-step explanation:
Three squares shown in the figure are formed on the sides of the given right triangle.
By Pythagoras theorem,

False
Therefore, Option (A) shows the areas of three squares.
the sum of three consecutive even integers is 30 more than the smallest integer. Find the largest integer.
Answer:
10 1/4
Step-by-step explanation:
Assume x as the smallest integer.
Since it is consecutive, you have to add 1 in order to get the next integer.
Equation:
x+x+1+x+2=x+30
x=8 1/4
You need to add 2 to get the largest integer.
So, 8 1/4 + 2 = 10 1/4

A transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°. What is the value of x?
Answer:
x=116°
Step-by-step explanation:
If a transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°, then the sum of those angles is equal to 180°.
ATQ,
x°+(x-52)°=180°
2x=180°+52
⇒2x=232
⇒x=116°
So, the value of x is 116°
