Answer:

8) x = 5.41

9) x = 45

10) x = 2.25

Step-by-step explanation:

8) 17/15 = 10/(2x-2)

150 = 34x - 34

reduce:

34x = 184

x = 5.41

9) 6/16 = (x-12)/(2x-2)

16x - 192 = 12x - 12

reduce:

4x = 180

x = 45

10) (x-9)/15 = (2x-9)/10

10x - 90 = 30x - 135

reduce:

20x = 45

x = 2.25

If x=9 and y=- -2 evaluate the following expression:<br><br> x+y

mel-nik [20]

Answer:

x + y = 11

Step-by-step explanation:

You would need to substitute the numbers into the expression.

Evaluate means that we need to work out what the answer would be.

x + y is equivalent to 9 - - 2.

- - is equivalent to +.

Therefore you would do 9 + 2, which equals 11.

Hope this helps :)
