3/4+2/3= 17/12
Step-by-step explanation:
If you're solving for a, you would add 32 to both sides
2a=32
then you would divide by 2
a=16
The answer would be D.
you would start by choosing one of the variables to eliminate, i chose to eliminate X first. in order to eliminate X, i had to multiply the second equation by -2. X then cancelled out, and i solved for the Y the same way you would a 1 step equation. Y=-4
I then took the first original equations, plugged Y in, and solved for X. X=3.
Hope this helps!
Answer:
Hello,
c) 720
Step-by-step explanation:
consonants : 5
5 x 4 x 3 x 2 x 1 = 120
other letters : 3
3 x 2 x 1 = 6
and 6 x 120 = 720
720 arrangements here
The average of 5, 7, 12, and 12, is (5 + 7 + 12 + 12)/4.
(5 + 7 + 12 + 12)/4 = 36/4 = 9.
The average is 9.
