According to the picture, you can assume that angle X is congruent to angle Y due to their triangle shape. Here is the work:

1. Set the equations equal to one another: 4x-8 = 2x

2. Move the variables to get the "x" values on one side: 2x = 8

3. Divide by 2 to get "x": x = 4

4. Plug in "x" into the Angle X equation: 4(4)-8 = angle x....16-8....8

Angle X is 8 degrees. Hope this helped :)

Explain the steps to solve (3+15)+ 25-10X3.

faust18 [17]

The answer is 43-30x because you always add the parenthesis first which now you have 18+25-10x3 then you calculate the product 18+25-30x. after all that you then add all the numbers and get 43-30x. hope this helps

Answers : A and D

Step - by - step explanation :

tip : when finding constant of proportionality it's always Y divided by X

A = what is 22.5 divided by 3 ? 7.5 ( now multiply 7.5 by the next X [ 4 ] )

what is 7.5 x 4 ? 30 ( and since on the graph it also says 30 then you can assume this one has a proportional relationship )

B = what is 12 divided by 3 ? 4 ( now multiply 4 by the next X [ 5 ] )

what is 4 x 5 ? 20 ( and because the graph says 25 then you know it's NOT a proportional relationship )

C = what is 8.5 divided by 2 ? 4.25 ( now multiply 4.25 by the next X [ 5 ] )

what is 4.25 x 5 ? 21.25 ( and because the graph says 22.5 then you know it's NOT a proportional relationship )

D = what is 10 divided by 2 ? 5 ( now multiply 5 by the next X [ 3 ] )

what is 5 x 3 ? 15 ( and since on the graph it also says 15 then you can assume this one has a proportional relationship )

( sorry it took me so long to write this )

What is the answer to this problem -2x – 4 < 3x + 21

horsena [70]

Start with

$-2x-4 < 3x+21$

Add 2x to both sides:

$-4 < 5x+21$

Subtract 21 from both sides:

$-25 < 5x$

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

$-5 < x$

So, the answer is $x > -5$

Jesse added two more numbers to his expression, but the sum did not change. What could the two new numbers be? Explain why the n

kenny6666 [7]

Answer:

0 and 0

Step-by-step explanation:

The only number that can be applied to the expression without changing the sum is 0, for example 5 + 10 = 15, adding 2 0's will be 0 + 5 + 10 + 0 = 15 :D
