First problem:
n/4 + 2 = -9
-2 -2
n/4 = -11
x4 x4
n = -44
Check:
-44/4 + 2 = -9
-11 + 2 = -9
-9 = -9
Second problem:
3/4x = -12
0.75x = -12
-------- ----
0.75 0.75
x = -16
3/4 * (-16) = -12 OR 0.75 * (-16) = -12
-12 = -12
Still get the same answer.
Because tens numbers are easier to work with. If you have the problem 9+3, you can take one out of three and add it to the nine to get 10+2.
2 wks = 38 cm SO
1 wk= 19 cm
19 cm a week
19 x 3 = 57
1/2 wk = 8 cm
57 + 8 = 65 cm in 3 1/2 weeks
They can buy 4 tickets, with a little bit left over.
Answer:
A
Step-by-step explanation:
To find (f ○ g)(x) substitute x = g(x) into f(x), that is
f(g(x))
= f(2x - 1)
= 3(2x - 1) + 14
= 6x - 3 + 14
= 6x + 11 → A
