The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
Answer:
x=20
Step-by-step explanation:
These are verticle angles, meaning the two should equal one another. If one angle is 60, its vertical angle is x+40.
x+40=60
x=20 (subtract 40 from both sides)

−4x−24x+24=10(12−2x) explain how you sloved it...i rllly need this!!!!
Answers
Answer:
x=-12
Step-by-step explanation:
first collect all the like terms -28x + 24 = 120-20x
then move variables and constants to the correct side -28x + 20x = 120-24
collect like terms again -8x = 96
divide both side by -8 so -8x/-x n 96/-8 you get x=-12 bc -8 time -12 = 96
Answer:
x = -12
Step-by-step explanation:
First, combine like terms
[tex]-4x-24x+24 = 10(12-2x)\\-28x+24 = 10(12-2x)[/tex]
Then, use the distributive property on the right side
[tex]-28x + 24 = 120 - 20x[/tex]
Now, add 28x to both sides to get the Xs all together
[tex]24 = 120 + 8x[/tex]
Next, subtract 120 from both sides:
[tex]-96 = 8x[/tex]
divide both sides by 8:
[tex]-12 = x[/tex]
This means the answer is x = -12

A taxi charges $1.75 plus a fee of $0.75 for each mile traveled. The total cost of a ride, without a tip, is $4.75. How many miles is the trip?
Answers
Answer:
The trip contains 4 miles.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptGiven that A taxi charges $1.75, meaning the initial condition of the trip is to charge $1.75.
Thus, y-intercept b = 1.75
Also, the taxi charges a fee of $0.75 for each mile traveled.
Thus, rate of change or slope m = 0.75
Let 'y' be the total cost
Let 'x' be the number of miles
Given that the total cost of a ride, without a tip, is $4.75.
so substitute y = 4.75, rate of change or slope m = 0.75, and the y-intercept b = 1.75 in the slope-intercept form of the line equation
y = mx + b
4.75 = 0.75(x) + 1.75
switch sides
0.75(x) + 1.75 = 4.75
subtract 1.75 from both sides
0.75x + 1.75 - 1.75 = 4.75 - 1.75
0.75x = 3
divide both sides by 0.75
0.75x/0.75 = 3/0.75
x = 4 miles
Therefore, the trip contains 4 miles.

The first equation should be multiplied by -3 and the second equation by -7. The first equation should be multiplied by - 7 and the second equation by 3 . The first equation should be multiplied by -7 and the second equation by -3.
Answers
Answer:
The first equation should be multiplied by - 7 and the second equation by 3
Step-by-step explanation:
Given
[tex]9x + 3y = -18[/tex] -- (1)
[tex]8x + 7y = 10[/tex] -- (2)
Required
How to eliminate y
In (1), the coefficient of y = 3
In (2), the coefficient of y = 7
Multiply the first equation by -7
[tex]-7(9x + 3y = -18)[/tex]
[tex]-63x -21y = 126[/tex] --- (3)
Multiply the second by 3
[tex]3(8x + 7y = 10)[/tex]
[tex]24x + 21y = 30[/tex] -- (4)
Add the results together:
[tex]-63x -21y = 126[/tex]
[tex]24x + 21y = 30[/tex]
[tex]-------------------------[/tex]
[tex]-63x + 24x -21y +21y = 126+30[/tex]

A line has an x-intercept of 2 and a y-intercept of 5. What is the equation of the line?
Answers
Answer:
y = -2.5x + 5
Step-by-step explanation:
Here, given the x and y intercept, we want to write the equation of the line
The general equation form is;
y = mx + b
where m is the slope and b is the y-intercept
Using the given points, we have that;
(2,0) and (0,5)
b is 5
so we have;
y = mx + 5
to get m, set (2,0); x = 2 and y = 0
0 = 2m + 5
2m = -5
m = -5/2 = -2.5
So the equation is;
y = -2.5x + 5

2. We need to get rid of all the parenthesis in this term. [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex]
All negative factors will change the sign.In the problem [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex] there isn't any negative factors. So the sign will not change.[tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex] is now [tex]2(x^4+9)(\frac{1}{x(x^2+1)}[/tex]

Answers
Answer:
12 times
Step-by-step explanation:
1 quart = 32 ounces
3 quart = x
x = 3 × 32 ounces
x = 96 ounces
The number of times of he need to fill an 8-ounce measuring cup to fill the pot is calculated as:
= 96 ounces/8 ounces measuring cup
= 12 times
Therefore, Alan needs to fill an 8 ounce measuring cup 12 times in order to fill the pot of soup.
13x = 130 Solve for x
Answers
Answer:
x = 10
Step-by-step explanation:
You need to isolate x, so divide by 13. 130/13 = 10.
Simplified, x = 10.
The solution to the given equation is 10.
The given equation is 13x = 130.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose 13 to the other side of the equation, we get
13x = 130
x=130/13
x=10
Therefore, the solution to the given equation is 10.
