Usually the easiest way to solve this is by using a calculator. Of course only if your teacher allows you too.
X= 4/5
Because...
You turn all the missed numbers in to improper fractions, then after you add all the ones with x’s after that you should get 7 then divide 7 by 28/5. Which equals 4/5
Answer:
C = (7, 6)
Step-by-step explanation:
The problem statement tells us the relation between the points is ...
(B-A)/(C-A) = 2/7
7(B -A) = 2(C -A) . . . . . . multiply by 7(C-A)
7B -7A +2A = 2C . . . . . add 2A
C = (7B -5A)/2 . . . . . . . divide by 2
C = (7(2, -4) -5(0, -8))/2 = (14, 12)/2 . . . . . fill in the values of A and B
C = (7, 6)
In order to solve this equation, try to get
the variable by itself. Begin by treating forgetting about 5 in 5a. This makes a/7=25. Multiply 7 and 25 to get 175, then place the 5 back in from of the a. Then divide 175 by 5a and get 35.
x=35
