Answer:
Step-by-step explanation:
The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.
Perform the indicated multiplication, obtaining:
8x - 20 = 9x - 18.
Then combine like terms: -2 = x, or
x = -2.
To complete the formal check, substitute -2 for x in the first equation. This results in:
(1/3)(-4 - 5) = (3/4)(-2 -2), or
-3 = -3
... which is obviously true.
You know that -3 is the Y intercept(vertical graph line) and then continue 2/1 every x value that is plugged in.
Answer:
192
Step-by-step explanation:
both triangles are 12 in and the square is 168
so 12+12+168= 192in
5/7 4/6 Do a cross multiplication 6*5 and 7*4
6*5 7*4
30 28
30 is bigger than 28. Therefore 5/7 is greater than 4/6
Yes 5/7 is greater than 4/6.
I hope it is not that complicated.
