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.

The 95% of 80 is 76. So, 76 answers are correct.
Therefore out of 80 Andrew did 76 questions correctly.
Answer:
every point of the object must be moved in the same direction
Step-by-step explanation:
each point the same distance horizontally and the same distance vertically.
The first answer of part A is 32
So 4y means you have to multiply 4 by y, which is 20 since 4x5=20
And then you add 12, which is 32.
The second answer to part A is 40
With the second question of part a, the expression is basically saying 4 times whatever 5+3 is. So 5+3= 8, and 4(8) is 40
For part B, they are equivalent because let’s pretend y=2. 12+4y= 20. And then 4(y+3) would equal 20 because 4(2)=8 and 4(3)=12 and 8+12=20. This might not be the answer that your teacher is looking for, but it’s still a right answer so technically they can’t say it’s wrong unless you have a super unfair teacher
Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. ... This is a function since each element from X is related to only one element in Y.
