Answer:
1) 8 2) -33/9
Step-by-step explanation:
1) (1/2)x = -1/2 + 9/2
(1/2)x = 4 x = 8
2) distributing 3/2, 9x/2 - 15/2 = -24
9x/2 = -24 + 15/2
9x/2 = -33/2
9x = -66/2
9x = -33
x = -33/9
Answer:
the answer to - 2/5 -4/5 + - 9/10 is -2.1
Using equations we know that the value of x needs to be (E) 4 to make HL congruent to AC.

What are equations?</h3>
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
So, HL is a hypotenuse that will be congruent to the hypotenuse AC.
We know that HL is 3x + 3.
Ac is 15.
Then the equation will be:
3x + 3 = 15
Now, solve the equation to get x as follows:
3x + 3 = 15
3x = 15 - 3
3x = 12
x = 12/3
x = 4
Therefore, the value of x needs to be (E) 4 to make HL congruent to AC.
