Answer:
The answer is B
Step-by-step explanation:
f(x) = 2x-1
f(0) = 2(0)-1
= -1
f(2) = 3
f(4) = 7
f(6) = 11
f(8) = 15
Pretty sure this is a waning crescent! I had a whole chapter on it!
The answer is
To find how many ounces you need to make, you multiply the number of packs by how many ounces.
So, it would look like:
36*2.35=84.6
15*10.8=162
Then you add the ounces together and you have your answer:
162+84.6=246.6 ounces
Answer:
7/20
Step-by-step explanation:
Convert them so they have the same denominator.
1/4 + 1/10
A common denominator is 40 (I'm just choosing an easy one for now, rather than the smallest one)
1/4 * 10/10 = 10/40
1/10 * 4/4 = 4/40
10/40 + 4/40
Add the numerators
(10 +4)/40 = 14/40
Simplify the fraction
14/2 = 7 40/2 = 20
7/20
To use mental math think instead of 81 to 80 and 16 to 10 and subtract that and add the other numbers and subtract that and you will have your answer presto!
