Answer: x=6
Step-by-step explanation:
To solve for x, we want to isolate the variable.
[get common denominator]
[add fractions]
[combine like terms]
[multiply both sides by 8]
[subtract both sides by 14]
[divide both sides by 15]
Now, we know that x=6.
Answer:
9^-4
Step-by-step explanation:
9^-6=?*9^-2
Let the unknown=x
9^-6=x*9^-2
9^-6=9^-2(x)
x=1/9^6÷1/9^2
=1/9^6×9^2/1
=9^2/9^6
x=1/9^4
x=9^-4
Check
9^-4*9^-2
=9^-4-2
=9^-6
The answer is 275 because when you multiply 11 by 25 you get 275
Answer:
22= 70
23= 20
Add up the angles you know and subtract/add to figure out what value is missing to make it 180
We need to get the x separately on one side and the numbers on another side.
To do this we divide both sides by 1/6.
x = 24
As you can see when dividing both sides of the equation by 1/6 it leaves the x on one side and another side for the number that x is equal to.
