Select the best equation needed to solve for x; then solve for x:

A. 5x+12=x; x =14
B. 5x+12=x; x=28
C. 5x+12+x=180 ; x=14
D. 5x+12+x=180 ; x=28

Answers

Step-by-step explanation:

A. 5x=12x-14

you will  simplify the equation to the form, which is simple to understand  

5x=12x-14

We move all terms containing x to the left and all other terms to the right.  

+5x-12x=-14

We simplify left and right side of the equation.  

-7x=-14

We divide both sides of the equation by -7 to get x.  

x=2

B.   5B+12=BB=28

you will  move all terms to the left:

.5B+12-(BB)=0

you will  move all terms containing B to the left, all other terms to the right

.5B-BB=-12

the answer is A yea yea yea yessir

Complete the following table so that it represents a linear function and determine the rate of change.

Answers

Answer:

let's say x1 = y2. for instance, that would mean that for every X, y would go up by 2. That would mean -1x = Y-2 because to get to -1 you have to subtract 1 by 2 because there is still 0 to account for.

so the table would look like this

-3=-6

-1=-2

1=2

3=6

5=10

That person is 100% correct!

Answer:

Question 8 is 21, Question 9 is 20.

Step-by-step explanation:

Ratios are very easy if you can find a relationship between them. For #8,  to get from 2 to 6 is to multiply 3. Then we multiply 7 and 3 to equal 21. This will be equivalent ratios. The next one is the same thing, to get from 6 to 24, we must multiply 4. We know that to make it equivalent we must multiply 5 with 4 which equals 20. Also we can do this with proportions  2/7 = 6/x. We cross multiply which equals 2x=42. We solve it like an algebraic equation which equals 21. We set up proportions for 5/6 = x/24. We cross multiply which equals 6x = 120. We solve this like an algebraic equation which equals to 20.

Cinderella made many new friends at the castle. After asking her fairy godmother to help, she invited her friends to go on a picnic. There were 36 heads and 104 legs in the group of horses, carriages, and riders. How many horses and how many people were there?

Answers

Answer:

104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people

Step-by-step explanation:

Angle TUR is a total of 125 degrees and angle RUQ is a total of 145 degrees. You find the measure of RUQ by subtracting 35 degrees from 180 degrees, this will give you the 145 degrees. So angle RUQ is greater than angle TUR by 20.
