Answer:
C i think
Step-by-step explanation:
you do 13x90 then divide by 5x
First 8.58
Second 8.508
Third 7.5
Fourth 7.058
From the given equation
105% * 90 = 200% * x
105/100 * 90 = 200/100 * x
105*90 = 200*x
x = 105*90/200
X = 21*9/4
X = 189/4
x = 47.25
Value of x = 47.25 or 47 1/4
Multiply the first digit by 3 then subtract the answer by 2. Rule: x 3 - 2
X=-1
12/-4=-3
-3+2=-1
The correct answer is -1
