Since you are trying to isolate
, you will need to remove the 13 through division:
![\dfrac{13x}{13} = \dfrac{78}{13}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B13x%7D%7B13%7D%20%3D%20%5Cdfrac%7B78%7D%7B13%7D%20)
![\boxed{x = 6}](https://tex.z-dn.net/?f=%20%5Cboxed%7Bx%20%3D%206%7D%20)
Our answer is x = 6.
A triangle is equal to 180. Using that, we can make a equation.
6x-3 + 3x+6 + 5x = 180
Combining the like terms, we get:
14x+3 = 180
Subtract 3 on both sides.
14x = 177
Finally, divide 177 by 14.
x = 177/14 or about 12.6
Answer:
less than or equal to -26
It should be 7,620 since 10x10x10 is 1,000 and you multiply that by 7.62 and it equals 7,620
Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
