Answer:
7/12 of the students
Step-by-step explanation:
So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.
The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.

It should look something like this: 15/25 = 18/x
With this equation set up you can solve by cross multiplying. 25(18)=15x
Then start sloving:
25(18)=15x
450=15x
450/15=15x/15 (divide both sides by 15)

Solve the simultaneous equations
2x + 4y = 22
2x + 2y = 15
Answer:
1. x= 11+-27
2.x = 7.5 + -1y
Step-by-step explanation:
1. Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 22 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 22 + -4y
2x = 22 + -4y
Divide each side by '2'.
x = 11 + -2y
Simplifying
x = 11 + -2y
2.Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
2x + 2y + -2y = 15 + -2y
Combine like terms: 2y + -2y = 0
2x + 0 = 15 + -2y
2x = 15 + -2y
Divide each side by '2'.
x = 7.5 + -1y
Simplifying
x = 7.5 + -1y

A rectangle is 12 inches long and 2 inches wide. Find its area. A 22 square inches 14 square inches 24 square inches 26 square inches
Area of given rectangle = 24 square inches.
The correct option is C.
What is rectangle?A rectangle is cyclic: all corners lie on a single circle. ; It is equiangular: all its corner angles are equal (each of 90 degrees).
Given,
Length of rectangle = 12 inches
Width of rectangle = 2 inches
Area of rectangle = length × width
= 12 × 2
Area of rectangle = 24 square inches.
Hence, 24 square inches is the area of rectangle.

3/5x - 7 = 23
A. x = 40
B. x = 45
C. x = 50
D. x = 55
Answer:
(C) x=50
Step-by-step explanation:
[tex]\frac{3}{5 }x -7=23[/tex]
[tex]\frac{3x}{5} -7=23[/tex]
[tex]\frac{3x}{5} -7+7=23+7[/tex]
[tex]\frac{3x}{5}=30[/tex]
[tex]3x=30* 5[/tex]
[tex]3x=150[/tex]
[tex]x=50[/tex]
Answer:
(C) X = 50
Step-by-step explanation:
(3/5)*x-7 = 23 // - 23
(3/5)*x-23-7 = 0
3/5*x-30 = 0 // + 30
3/5*x = 30 // : 3/5
x = 30/3/5
x = 50 (Sorry if it's wrong)

PARKING Stephanie is drawing the layout of a parking lot on a coordinate grid and needs to verify that two
sides meet in a right angle. In her sketch, one side of the parking lot has endpoints A(0,0) and B(50,0). The
second side of the parking lot has endpoints B(50,0) and C(18, 24). How can Stephanie prove that the two
sides of the parking lot meet in a right angle? Select all that apply.
® Find the slopes of AC and CB. If the product of the slopes is -1, then the sides meet in a right angle.
B Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
© Find the slopes of CB and AB. If the slope of AB is the opposite of the slope of AC, then the sides meet in
a right angle.
Find AB, BC, and AC. If AB + BC = AC, then the sides meet in a right angle.
Find AB, BC, and AC. IfAB2+ BC = AC?, then the sides meet in a right angle.
Answer:
The answer is: Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
Step-by-step explanation:
From Analytical Geometry, two lines are perpendicular to each other if and only if [tex]m_{1}\cdot m_{2} = -1[/tex], where [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are the slopes of each line, respectively. According to this, the following expression must be observed:
[tex]m_{AB} \cdot m_{BC} = -1[/tex] (1)
Each slope can be determine by definition of the slope of a Secant Line:
[tex]m_{AB} = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)
[tex]m_{BC} = \frac{y_{C}-y_{B}}{x_{C}-x_{B}}[/tex] (3)
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex], [tex]x_{C}[/tex] - x-Coordinates of points A, B and C.
[tex]y_{A}[/tex], [tex]y_{B}[/tex], [tex]y_{C}[/tex] - y-Coordinates of points A, B and C.
If we know that [tex]x_{A} = 0[/tex], [tex]y_{A} = 0[/tex], [tex]x_{B} = 50[/tex], [tex]y_{B} = 0[/tex], [tex]x_{C} = 18[/tex] and [tex]y_{C} = 24[/tex], then the relationship between slopes is:
[tex]m_{AB} = \frac{0-0}{50-0}[/tex]
[tex]m_{AB} = 0[/tex]
[tex]m_{BC} = \frac{24-0}{18-50}[/tex]
[tex]m_{BC} = -\frac{3}{4}[/tex]
[tex]m_{AB}\cdot m_{BC} = 0\cdot \left(-\frac{3}{4} \right)[/tex]
[tex]m_{AB}\cdot m_{BC} = 0[/tex]
Which means that both line segments are not perpendicular to each other.
In a nutshell, we need to find the slopes of AB and CB, if the product between both slopes is -1. Then, the sides meet in a right angle.
