Answer:

x = 14, y = 37

Step-by-step explanation:

The angle vertically opposite (4y-10) is also a corresponding angle to (9x + 12) so that means that angles (4y-10) and (9x+12) are equal.

4y-10 = 9x+12 -----Equation 1

You also know that (4y-10) and 3x add up to 180° since they both lie on a straight line.

4y-10+3x = 180 -----Equation 2

From the above equation, I'm going to isolate (4y-10) so that I know a value that I can substitute in Equation 1.

4y-10 = 180-3x -----Equation 3

Substitute 4y-10 = 180-3x into Equation 1.

4y-10 = 9x+12

180-3x = 9x+12

Put the like terms together.

180-12 = 9x+3x

Evaluate.

12x = 168

Find x.

x = 168 ÷ 12

x = 14

Subsitite x = 14 into Equation 3.

4y-10 = 180-3x

         = 180-3(14)

         = 180-42

         = 138

Isolate 4y.

4y = 138+10

    = 148

Find y.

y = 148 ÷ 4

y = 37

Answer:

Step-by-step explanation:

3x + 9x +12 = 180 {linear pairr}

    12x + 12 =180

        12x = 180 - 12  

         12x = 168

             x = 168/12

x = 14

3x  = 3*14 = 42

4y - 10  + 3x = 180         {linear pair}

4y - 10 + 42 = 180

         4y + 32 =180

              4y  = 180 - 32

              4y = 148

                y = 148/4

               y = 37

Bingel [31]

Answer:

603.71

Step-by-step explanation:

Use a function to solve this.

F(x)

Now lets put in the data for the function.

We have 910, which is the orginal number. This should be the first number, and will have to be multiplyied by the other numbers in the function to find the answer. I think of all these numbers like the things in a penut butter and jelly sandwhich, is sounds very nice since I am hungry.

F(x) = 910 *

Next, we have 5%, which is what we are taking from 910. So, we can think of this as 910 being multiplyied by 0.95. Lets add this to our growing penut butter and jelly sandwhich. The reason I put this into a parenthese is so that the 910

F(x) = 910 * (0.95)

Now for the last step, we must add in the years. So, eahc year we reduce the 910 by 5%, and we need to do this 8 years This means that the 910 times 0.95 must repeat 8 times. To do this, we need ot use exponent. This exponent is 8. So, here is our completed function:

F(x) = 910 * (0.95^8)

Lets plug this into a calculator, since doing this out on paper would be a real pain and will take far to long. I would probably die of hunger and never get a penut butter and jelly sandwhich if I did this out on paper.

In the end, you should get 603.7125 blah blah blah it goes on for a long time. I attached a file of what it looks like in the calculator if you want some evidence.

Oh, you said you want it rounded to the nearest whole number. Well, lets remember our rounding here. Anything below 5 goes down, anything 5 and higher goes up. Since we have 603.7125, we can round that too 603.71

<u>603.71</u>
