Answer:

64

Step-by-step explanation:

The common difference is 80 / (8 - 3)

= 16

So f(18) - f(14)  =  (18 - 14) * 16

=  54

Andrew got a 95% on the test. If there were 80 questions on the test, and every question worth the same, how many questions did
Lemur [1.5K]

Answer:

Out of 80 questions Andrew did 76 questions correctly.

Step-by-step explanation:

Total number of questions is 80.

It is given that he got 95% on the test. It means he answered 95% of the total questions correctly.

First we have to calculate 95% of 80.

80\times \frac{95}{100}=76

The 95% of 80 is 76. So, 76 answers are correct.

Therefore out of 80 Andrew did 76 questions correctly.

Use distributive property to write an expression that is equivalent to each expression. -8(-x-3/4y+7/2
Lesechka [4]

Answer:

  8x +6y -28

Step-by-step explanation:

The outside factor applies to each inside term, so the equivalent expression is ...

  -8(-x -3/4y +7/2) = 8x +6y -28

Applying the distributive property once again, we can also write the equivalent expression ...

  = 2(4x +3y -14)

__

There are an infinite number of other equivalent expressions. The problem statement is non-specific as to the acceptable form.
