Answer:
7
Step-by-step explanation:
use distributive property first
2x-4=10
then, add positive 4 to -4 and 10 because opposite signs cancel out
2x=14 then we divide
Substitute the values of the size of the 5 batches to the
model.
For example
@x = 20
f(20) = 2*20 – 23 = 17
f(25) = 2*25 – 23 = 27
f(26) =29
f(27) = 31
f(34) = 45
Therefore the answer is the first choice (17, 27, 29, 31,
42)
Divide 7 and 9
7/9 = 0.77 (repeating)
0.77 (repeating) rounded would be 0.78
0.78 is your answer
hope this helps
Y= 3 which would be choice A, because both equations are going to be set equal to eachother, so with that you would put

subtract 5y from 7y, and add the 3 from the left to the 3 on the right. this would leave you with 2y=6 so in this case you would divide both sides by two to get the answer of 3 which is choice A.
