When angles are complementary, the sum of their measures is 90 degrees (meaning the two angles add up to 90). The two complement

Answer:

x=22

The measure of the angle 2x-10 is 34 degrees.

The measure of the angle 3x-10 is 56 degrees.

Step-by-step explanation:

What you first want to do is add both of the equations up so that they equal 90 which would look like 2x-10+3x-10=90 next add up all like terms to get 5x-20=90. Now you want to add 20 on both sides to get 5x by itself which leaves you with 5x=110. Now you want to isolate x by dividing by 5 on both sides to finally get x=22.

To find the measure of the other two angles you want to simply plug in 22 as the value of x in each so you get 2(22)-10=34 and 3(22)-10=56.

Lelu [443]

i dont know if this is correct

AT (X)= 6X^2 another part to this equation is: AT/6= X^2 and the answer is X= AT/6^1/2b.

The perimeter of a square can represent by 16x + 24. Willa wants to write an equivalent expression for the perimeter that shows
Maslowich
The diagram shows that all the sides of the rectangle are congruent. Since the perimeter all of the sides added up, all you have to do is divide the perimeter by 4.

Therefore, the perimeter, which is 16x + 24, can be divided by 4 to find the length of one side. 

16x + 24/4 = length of one side. So, the length of one side is 4x + 6.

Hope this helped!

What is the answer to 3/x-2 is ≥12
Tju [1.3M]

Answer:

The answer to your question is 0 < x ≤ 3/14

Step-by-step explanation:

Here are the steps to solve it.

First, you need to solve your inequality step-by-step:

3/x −2 ≥ 12

-2x + 3/x = ≥12

Next, find the critical points of the inequality:

2x + 3/x = 12

−2x + 3 = 12x (Multiply both sides by x)

−2x + 3 − 12x = 12x − 12x (Subtract 12x from both sides)

−14x + 3 = 0

−14x + 3 − 3 = 0 − 3 (Subtract 3 from both sides)

−14x = −3

-14x/ -14 = -3/ -14 (Divide both sides by -14)

So, that gives you your answer:

x = 3/14

A gasoline pump delivers 4 2/5 gallons of gas per minute. How many minutes will it take to fill a gas tank that holds 17 1/4 gal
Liono4ka [1.6K]
Well if it pumps 4 2/5 per minute that is equal to 4 4/10 in a minute or 4.4 because you multiply the top and bottom of the fraction by two. it’s still the same fraction but it is easy to convert to a decimal now. you could use this fraction but it’s much easier to use decimals. Because the first number is a decimal you should make the second one a decimal too. To do this you need to know that 1/4 of 100 is 25. so now we have these numbers and all you do now is divide 17.25 by 4.4 which could be rounded to 4 because it’s a long decimal

Find the 10th term of the following geometric sequence: 2, 8, 32, 128.        A. 164,357   B. 621,325   C. 524,288   D. 248,221
Galina-37 [17]
Common ratio = 8/2 = 32/8 = 4

10th term  = a1*r^(n - 1)   where a1 = 2 , r = 4 and n = 10
                = 2 * 4^9
                =  524,288
