8 is the answer if u do some equation gymnastics as i call them
The answer for w is w=3.5 <span />
For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Twice a number plus 10, is represented as:
Three times that number less 4. is represented as:

Thus, the complete expression is:

Subtracting 3x from both sides of the inequality:

Subtracting 10 from both sides of the inequality:

Equal signs are added and the same sign is placed:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

The solution is given by all values of "x" less than 14.
Answer:

The mistake is that that is an equilateral triangle with the same answer for each side which is 6 so AC=6 BC=6 BA=6 all sides equal 6
To solve this problem first subtract the 4 from 120.
120 - 4 = 3y + 4(-4) =
116 = 3y.
Then divide both sides by three.
116 / 3 = 3y / 3 =
38.6666666667 = y
y = <span>38.6666666667.</span>
To double check the answer , 38.6666666667 x 3 + 4 = 120.
