Answer:
2x−3=x
Move all terms containing x
to the left side of the equation.
Subtract x
from both sides of the equation.
2x−3−x=0
Subtract x
from 2x
x−3=0
Add 3
to both sides of the equation.
x=3
Start by representing the lengths of the three sides of your triangle:
first side: x-4 (inches)
second side: x (inches)
third side: (x-4) + 3 (inches)
Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):
x-4 + x + x-4 -3 = 15
3x-11=15
3x=26
x=26/3
Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).
Answer:
Step-by-step explanation:
123/6 x 7[(654 + 2) x (12/3)].....do whats in parenthesis first
123/6 x 7[656 x 4] ......do whats in brackets
123/6 x 7(2624) ....do multiplication/division from left to right, whichever comes first
20.5 x 18,368 =

"Centi" means 100 so there are 100 centimeters in a meter. 4 times 100 equals 400 so 4 meters is equal to 400 centimeters.
