Answer:
Option D.
Step-by-step explanation:
In order to resolve this problem, we are going to transform every fraction on a decimal number.
A) 
is a mixed fraction. To get a proper fraction, we let the denominator as 2, and to get the numerator we multiply 2 by 2, and we add 1, as seen on the attached picture.
So:
We divide 5 by 2 and we get 2,5.
So, the first option is not true, as 1.5 is smaller than 2,5.
B) We divide 1 by 2 and get 0,5. They are equal numbers, we can't say that 0,5 is bigger than 0,5.
C) -2.5 is smaller than -1,5 so this option is not true.
D) 
We divide 7 by 2 and we get -3,5. In fact, -3,5 is bigger than -4.5, as there is a major distance from this negative number to cero.
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck
Answer: 1
Step-by-step explanation:
Y2 - Y1 / X2 - X1
-2 - 1 = -3
-1 - -4 = 3
-3/3 = 1
Multiply it out first.
90x+225-4=1
Combine like terms.
90x+221=1
Start isolating variable.
90x=-220
x=-220/90=-22/9
The answer is x=-22/9.
Hope this helps!
