7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20
Answer:
-5
Step-by-step explanation:
C because I did the mean value theorem and got that as the solution.
Answer:
f(3) = 10
Step-by-step explanation:
If x = 3 then fill in the x's on the original equation and solve;
f(x) = 2x + 4
f(3) = 2(3) + 4
2 x 3 = 6
6 + 4 = 10
So, f(3) = 10
Hope this helps!!!
