Answer:
Subtraction
Step-by-step explanation:
Since 8 is being added to the x, in order to get rid of it on the left side to solve for x you need to subtract 8 on both sides.
Answer:
-7/15
Step-by-step explanation:
You want to isolate the d variable so you take out anything on the side of d to make d alone. To make d isolate the 15/42 has to go.
So...multiply
* right side
the answer to the equation above is 1. d is now alone, because 1*d is just d.
Since you multiplied 42/15 on the right, you've to do the same thing on the left.
* left side
Divide the 6 by itself and also by 42. Or multiply the numerator and denominator.
The answer you get is -7/15.
Answer:
assume it's width as 'x'
So, it's length is '2x-3'
and the perimeter is equal to 66m
Step-by-step explanation:
So,equalize the equation
x + (2x-3) + x + (2x-3) = 66
remove the brackets
2x + 4x - 6 = 66
add 6 to both sides
6x = 60
x = 60 ÷ 6
= 10
so, the length is 2x-3 = 20 - 3 = 17 m
and the breadth is x = 10 m
