Answer:
If he earns (e) $7.75 per hour, this implies e = 7.75h.
Step-by-step explanation:
If you wanted to solve that-
e = 7.75h
193.75 = 7.75h
Divide both sides by 7.25
h = 25

The area (in square feet) of the school sign can be represented by
15x^2+x-215x2+x−2
Write an expression that represents the length of the sign.
Answer:
5x^2+2x-432
Step-by-step explanation:
15x^2+x-215×2+x−2
=15x^2+x-430+x−2
=15x^2+x+x-430-2
=15x^2+2x-432
The expression that represents the length of the sign is 5x - 2 feet.
What is Area of Rectangle?The area of Rectangle is length times of width.
The area of a rectangle is given by the formula A = length × width.
A = L × W
The given expression, 15x^2 - x - 2, represents the area of the sign in square feet. So we can substitute this expression for A and solve for L:
A = L × W
15x² - x - 2 = L × (3x + 1)
L = (15x² - x - 2) / (3x + 1)
If the height of the sign is (3x+1) feet, then the length of the sign is given by the area divided by the height:
L = (15x² - x - 2) / (3x + 1)
Substituting (3x+1) for the height, we get:
L = (15x² - x - 2) / (3x + 1) = [(3x + 1) (5x - 2)] / (3x + 1) = 5x - 2
Therefore, the expression that represents the length of the sign is 5x - 2 feet.

Pls help! Which function models the relationship shown by the line?
A y=-3x + 2
B y= 1/3x + 2
C y=-3x + 6
D y=-1/3x + 6
Answer:
C. y= -3x + 6
Step-by-step explanation:
line passes through +6 at the y axis
so it narrows it down to C and D
line passes through 2 at the x axis at 2,0
when line has x = 2 then y should be 0
only choice left is C. y= -3x + 6
0 = -3(2) + 6
0 = 0
alex has created an image that he wants to enter in a art contest the rules state that all images must be framed and have an area of 80 square inches, including the frame. the image has the dimensions 7 inches by 5 inches. what is the width of the frame
The width of the frame for the image is about 1.5 inches.
What is an area?Area is the amount of space occupied by a two dimensional object or figure.
Let w represent the width of the frame, hence:
Length of image and frame = 7 + w + w = 2w + 7
Width of image and frame = 5 + w + w = 2w + 5
Area of width and frame = (2w + 7)(2w + 5)
80 = 4w² + 24w + 35
4w² + 24w - 45 = 0
w = 1.5 inches
The width of the frame for the image is about 1.5 inches.

A probability distribution is a table showing all the possible values a discrete random variable can take, plus the probability that it'll take each value.
Let X be the score of a pair of fair six-sided dice
X can take the values 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12
Create a sample space (attached) to visually see the sums of different combinations and to help construct the probability distribution table (attached)
B) Reading from the table:
P(X ≥ 8) = P(X=8) + P(X=9) + P(X=10) + P(X=11) + P(X=12)
= 5/36 + 4/36 + 3/36 + 2/36 + 1/36
= 15/36 = 5/12
C) Reading from the table:
P(X ≤ 7) = P(X=7) + P(X=6) + P(X=5) + P(X=4) + P(X=3) + P(X=2)
= 6/36 + 5/36 + 4/36 + 3/36 + 2/36 + 1/36
= 21/36 = 7/12
D) Reading from the table:
P(X is even) = P(X=2) + P(X=4) + P(X=6) + P(X=8) + P(X=10) + P(X=12)
= 1/36 + 3/36 + 5/36 + 5/36 + 3/36 + 1/36
= 18/36 = 1/2
E) Reading from the table:
P(3≤X≤10) = P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7) + P(X=8) +
P(X=9) + P(X=10)
= 2/36 + 3/36 + 4/36 + 5/36 +6/36 + 5/36 + 4/36 + 3/36

Solve the following system of equations:
x+y+z=4
-3x-4y+4z=12
2x-y-4z=-1
Answer:
1) x=4-y-z
2) x=-12+4y-4z/3
3) x=-1+y+4z/2
Step-by-step explanation:
1) Subtract y+z from both sides.
x+y+z-(y+z)=4-(y+z)
Simplify
x=4-y-z
2) Subtract -4y+4z from both sides.
-4y+4z-(-4y+4z)=12-(-4y+4z)
Simplify
-3x=12+4y-4z
Divide both sides by -3
-3x/-3=12/-3+4y/-3-4z/-3
x=-12+4y-4z/3
3) Subtract -y-4z from both sides.
2x-y-4z-(-y-4z)=-1-(-y-4z)
Simplify
2x=-1+y+4z
Divide both sides by 2
2x/2=-1/2+y/2+4z/2
Simplify
x=-1+y+4z/2

In Mendel’s genetic experiments many characteristics of the plants were quantified, such as their height (tall or short), flower position (axial or terminal), and seed color (colored or white). Suppose 100 plants are measured, and 35 are tall with axial flowers and colored seeds. Further, suppose a total of 25 plants have white seeds, 4 of them being short and 6 having terminal flowers. There are no short plants with terminal flowers, and the total number of short plants is 25. How many plants have terminal flowers are tall and have colored seeds?
I put 6 as the answer and it is incorrect. Please Help.
The 19 plants have terminal flowers are tall, and have colored seeds.
It is given that in Mendel’s genetic experiments many characteristics of the plants were quantified, such as their height (tall or short), flower position (axial or terminal), and seed color (colored or white).
It is required to find the how many plants have terminal flowers are tall and have colored seeds,
What is the application of subtraction?In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
We have a number of plants = 100
Number of the tall with axial flowers and colored plants = 35
Total number of white seeds plants = 25
Number of plants that is short = 4
Number of plants having terminal flowers = 6
Total number of short plants = 25
The number of have terminal flowers are tall and have colored seeds:
= 100 - 35 - 25 - (25 - 4)
= 19
Thus, the 19 plants have terminal flowers are tall, and have colored seeds.
