In mathematics, the statement if a, then b, says that if a is true, then be is true. If you think about it, this makes sense too. That means that the answer is C., because of the definition of the statement.

Plz answer its easy math.
Serga [27]
<h2>Greetings!</h2>

Answer:

B and E

Step-by-step explanation:

The rules of indicies states:

x^{a} ÷x^{b} = x^{a-b}

So 3^{-8} ÷  3^{-4} =  3^{-8 - - 4} =  3^{-4}

So that means B is one of the correct answers.

To find the other correct value, you can divide the two fractions as stated in the question:

3^{-8} by 3^{-4} = \frac{1}{81}

81 is equivalent to 3⁴

So that means E is also correct.

Billy makes $5 a week in allowance plus $4 for each lawn that he mows.
Ad libitum [116K]

Answer:

$15 < $4n + $5

Step-by-step explanation:

We know that Billy needs to make more than $15 between his allowance and the lawns that he mows. This means our inequality should include $15<. Also, since Billy will make $4 per lawn, that means we need to multiply $4 by the number of lawns he needs to mow, n: $4n. So far we have the following: $15<$4n. Next, we know that he makes $5 each week, on top of what he makes mowing each law. This means we need to add the $5 to the $4n. When we put all of these pieces together, we will get the following inequality: $15<$4n+$5
