Which value of x makes the equation 3(x-6) = 8x-3(3x+7) true?
2 answers:
Answer:
Step-by-step explanation:
3x - 18 = 8x - 9x - 21
3x - 18 = -x - 21
4x - 18 = -21
4x = -3
x = -3/4
answer is A
Answer: OPTION 3. x=-3/4
Step-by-step explanation:
This question is basically asking for to solve the equation.
------------------------------------------------------------------
Given
3(x-6)=8x-3(3x+7)
Distributive property on both sides
3x-18=8x-9x-21
Combine like terms on the right side
3x-18=-x-21
Add x on both sides
4x-18=-21
Add 18 on both sides
4x=-3
Divide 4 on both sides
x=-3/4

Answer:
it's A
(-6,1)
Step-by-step explanation:
An = a1 * r^(n-1)
-405 = -5*3^(n-1)
3^(n-1) = 81
3^4 = 81 so n-1 = 3 and n = 4
Sn = S4 = -5 (1 - 3^4) / ( 1 - 3) = 400 / -2 = -200 Answer
A. about 14
divide 72/5= 14.4 which rounds to 14
