Answer:

<h2>The answer is 494</h2>

Step-by-step explanation:

$f(n) = -3+7(n-1) \\$

where

n is the nth term

From the question we are finding the 72nd term that's n = 72.

Substitute the value into the above formula and solve

That's

$f(72) = - 3 + 7(72 - 1) \\ = - 3 + 7(71) \\ = - 3 + 497$

We have the final answer as

Hope this helps you

What is 4/5 + 3/4 I need it for my homework

Vladimir79 [104]

Answer:

4/5 + 3/4 = $1\frac{11}{20}$ or 1.55

Step-by-step explanation:

This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.

The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:

The highest common factor of 4 and 5 = 4 * 5 = 20

This can now be used to solve 4/5 + 3/4 as follows:

4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 = $1\frac{11}{20}$ or 1.55

Therefore, we have:

4/5 + 3/4 = $1\frac{11}{20}$ or 1.55
