Take a ruler and put it on your desk and mesure from the centimeter side!!
Answer:
fx=8-3dx
Step-by-step explanation:
Number three is D and number 4 is also D.
Explanation for number three:
When you divide 12 by 3, you get 4. This gives us the number we need to multiply 10 by to get our answer. 10 x 4 = 40
Explanation for number 4:
In the last question, the first step to getting to the answer was to divide the first two numbers. This is no different. When you divide 32.5 by 5, you get 6.5. Then you multiply 10 and 6.5, which equals 65.
The idea for transitions for an equation like this is

where m = slope
h = how much left or right (note the negative)
k = how much up or down
moving 13 down would mean
k = -13
so

D. would be your answer
(20 + 22 + 17) - 7 - 12 - (9 - x) = 37;
59 - 19 - 9 + x = 37;
31 + x = 37;
x = C) 6
