Answer:
45
Step-by-step explanation:
add 6 on both sides to eliminate it(doing this will get us closer to the variable)
x/3=15
multiply both sides by 3
x=45
hope this helps!
Answer:
Mr. Martin's statement is correct.
Step-by-step explanation:
First we select a value of q that is less than 6:
q = 3
Then we <u>write the equation:</u>
And <u>solve for x</u>:
The solution is positive because x > 0.
--
Then we select a value of q that is not less than 6:
q = 9
Then we <u>write the equation:</u>
And <u>solve for x</u>:
The solution is negative because x > 0.
Answer:
-59/17 =x
Step-by-step explanation:
53=-6-17x
Add 6 to each side
53+6=-6+6-17x
59 = -17x
Divide each side by -17
59/-17 = -17x/-17
59/-17 = x
-59/17 =x
Answer:
1) x²-3x+9/4 = 81/4
2) x = 6, -3
Step-by-step explanation:
x²-3x-18=0
x²-3x=18
(b/2)² = (-3/2)² = 9/4; completing the square
x²-3x+9/4 = 18+9/4
(x-3/2)(x-3/2) = 81/4
x - 3/2 = ± 9/2
x = 3/2 ± 9/2
x = 6, -3
