The answer is 20, since if you set up the equation
x+80=3x
Move the x to the right by subtraction
80=4x
Divide by 4
x=20
18
Explanation:
60 • 30%
Or
60 • .3 = 18
Hope this helps!
Point A is in Quadrant I where the x and y are both positive.
Point B lies in between Quadrants II and III. Or it lies on the x-axis (If this is an option).
(4.2*10^-1)*(5.7*10^-1) = (4.2*5.7)*(10^-1 * 10^1)
23.94*10^-2 = .2394
moving the decimal one place to the left is the same thing as dividing by 10 or multiplying by
1/10. 2.394*10^-1, that is the answer you're looking for, B
