Time to rank up :D
soo
7a - 3 = 3 + 6a
-6a
a - 3 = 3
+ 3
a = 6!!
I got 1x + 27 which is the first one.
How I got it was..
4(x+3)+3(5-x)
4x+12+15-3x
1x+12+15
1x+27
Just take the x and do what the word problem says. Number one would be 15+X
Two would be 70-y and so on
Answer:
Step-by-step explanation:
Part A
To keep it simple, I will use v instead of vi, x instead of triangle x and t instead of triangle t.
The equation becomes: x = vt + 1/2at^2
Solve for a:
x = vt + 1/2at^2
x - vt = 1/2at^2
(x - vt)*(2/t^2) = 1/2at^2*(2/t^2) = a
a = 2(x-vt)/t^2
or writing in the right format
a = 2(Δx - viΔt) / Δt^2
