Hello from MrBillDoesMath!
Answer:
x = 7/8
Discussion:
3[x + 3(4x – 5)] = 15x – 24 =>
3x + (3*3)(4x-5) = 15x - 24 =>
3x + 9*(4x) - (3*3)*5 = 15x - 24 =>
3x + 36x - 45 = 15x - 24 => (add 24 to each side)
3x + 36x - 45 + 45 = 15x - 24 + 45 =>
39x = 15x + 21 => (as 45-24 = 21)
39x-15x = 21 => (subtract 15x from both sides)
24x = 21 =>
x = 21/24 = -7/8

Thats it.....
Do you need something else or just that?
Answer:
option c, x = 3
Step-by-step explanation:
Given:
- f(x) =
Since both equal f(x) they must be equivalent as well,
Apply exponent rule, 3 x 3 x 3 = 27
hence x = 3
THE ANSWER IS NOT IN THE LINK THAY THAT PERSON GAVE
Answer:
For chess club:
y1 = 16 + 1*x where y1=total number of members after x months
For film club
y2 = 4 + 4*x where y2=total number of members after x months
y1 = y2 at
16 + x = 4 + 4x
3x = 12
x = 4
Therefore, after 4 months they the same number of members (equals 20 members, 16 + 1*4 or 4 + 4*4).
