Answer:
x = 15
Step-by-step explanation:
9x - 5 = 7x + 25 ......(vertical angle and corresponding angle )
9x - 7x = 25 + 5
2x = 30
x = 30 / 2
x = 15
Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26
Step-by-step explanation:
5x - 3x = 10
2x = 10 Divide by 2
x=5
2(2x - 1) = 46 Distribute the 2
4x - 2 = 46 Add 2
4x = 48 Subtract by 4
x = 12
6x - 15 = 75 Add 15
6x = 90 Divide by 6
x=15
x + x - 10 =26 Add the x's together and the 10
2x = 36 Divide by 2
x = 18

The quotient of a number decreased by 7 and -2 is -10.
Step-by-step explanation:
First, a quotient is the answer to a division equation.
So its like y÷z=x
X is our quotient.
Since x is -10 when decreased by 7 and -2, we can write:
x-7-(-2)=-10
x-7+2=10
x-5=10
x=15
We now know that x is 15.
Using that, we can write out our equation.
Since you say do not solve, i have purposefully NOT solved this.
You should use y as a dividend and z as a divisor!
Good luck.

A recipe called for the ratio of eggs to cups of sugar to be 2:1. If you needed to use 6 eggs, how many cups of sugar would you need to use?
a.1 cup
b.3 cups
c.4 cups
d.6 cups
Answer:
u would have 3 cups of sugar
Step-by-step explanation:
Answer:
b.3 cups
Step-by-step explanation:
Since the ratio is 2:1 it means that for every 2 eggs you will have 1 cup of sugar.
2/1 multiped by 6/x
Cross multiply 6(1) and 2(x)
6 = 2x
Divide both sides by 2 to get the variable by itself.

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

Juli says she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6:10.
Which statement explains whether Juli is correct?
a. She is correct because she can multiply 6 and 10 by any number to form an equivalent ratio.
b. She is correct because 6:10 can be written as 1:2 and there are an infinite number of ratios for 1:2.
c. She is not correct because the multiplication table does not include multiples of 10.
d. She is not correct because 6:10 is equivalent to 3:5 and there are only 9 ratios in the multiplication table that are equivalent to 3:5.
This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.
Answer:
There are 10 counters in the bag and you want the 4
As their is only one for the probability is
1/10
There are now 9 counters left in the bag.
You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)
There are only four even counters in the bag of nine counters so the probability is
4/9
As you want both of these to occur, you need to multiply them
1/10 x 4/9 = 49/90
Step-by-step explanation:
The probability of getting a multiple of 3 both times is 2/30.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
We are randomly picking two numbers from 1-10.
Multiple of 3 between 1 and 10 are 3, 6, 9.
To find the probability:
Here, we are considering the that the numbers are chosen without replacement.
The probability of getting a multiple of 3 both times,
= 3/10 x 2/9
= 6/90
= 2/30
Therefore, the probability is 2/30.

PLS I NEED HELP ON THIS QUESTION
Answer:
Step-by-step explanation:
First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180
For the triangle on the left, sum up the angles and set it to 180 degrees.
60 + 38 + x = 180
x = 82 degrees
Now solve for y by doing this
82 + y = 180
y = 98 degrees
While I'm here, Ill solve for z because it will most likely ask in the next question.
26 + 98 + z = 180
z = 56 degrees
The measures of the angles of △ABC are given by the expressions in the table.
Angle Measure
A (6x−1)°
B 20°
C (x + 14)°
What are the measures of angles A and C?
Answer:
First You add all given angles up to equal 180 to give you x then you plug x into equations
Step-by-step explanation:
A= 125 degrees
C= 35 degrees
Answer:
Angle A = 125°
Angle C = 35°
Step-by-step explanation:
This is the equation you would have to solve:
Angle A + Angle B + Angle C = 180°
Fill in the values given:
(6x-1)° + 20° + (x+14)° = 180°
The parentheses don't really matter here. Go on to combine like terms. This gives you:
7x + 33 = 180°
Solve for x. Subtract 33 on both sides. This gives 7x = 147. Divide both sides by 7. This gives x = 21.
Now, go back and fill in 21 for x in the expressions for angles A & C.
Angle A:
6(21) - 1 = 125°
Angle C:
21 + 14 = 35°
You can check your answers using the first equation I mentioned:
Angle A + Angle B + Angle C = 180°
125° + 20° + 35° = 180°
This is a true equation. Therefore, the final answers are:
Angle A = 125°
Angle B = 20°
Angle C = 35°
