Solve 7+2x over 3 = 5
Please and thank you! x
Answer:
x = 4
Step-by-step explanation:
(7 + 2x) / 3 = 5
Cross product
7 + 2x = 5 * 3
7 + 2x = 15
Subtract 7 from both sides
2x = 15 - 7
2x = 8
Divide both sides by 2
x = 8/2
x = 4

Two parallel lines are cut by a transversal as shown below.
Suppose m<8=109. Find m<2 and m<3.
Answer:
measure 2 has to be 109 due to the alternate interior angles theorem. Measure 3 has to be 71 due to the supplementary angles theorem.
Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—is known as the vertex.
Given two parallel lines a transversal.
Angles 8 and 2 are alternate interior angles.
m∠8 = m∠2
m∠2 = 108°
Now,m∠2 and m∠3 are supplementary angles.
Therefore,m∠3 = 180° - 108° = 71°
Hence "Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively".

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.

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

The average speed would be 10.1 kilometers per hour.
Step-by-step explanation:
If we convert both times into minutes, it will make solving this much easier. After finding the speed for both legs, we can find the average by adding the two values together and dividing by 2. This results in 10.11430568 or can be rounded to 10.1.

Answer: 30
Step-by-step explanation: Assuming that the side lengths correspond with one another you can set up a ratio to solve
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)
