Step-by-step explanation:
3p + 7q = 55
7p + 7q = 91
(-)
-4p=-36
p=9
q=4
Twice the difference of a number and 3 is at most 27
2*(n-3) <=27
to solve
distribute
2n -6 <=27
add 6 to each side
2n <=33
divide by 2
n <=33/2
n<= 16 1/2
Answer:
you simply think of a number that when multiplied by itself it will give you that whole number
Step-by-step explanation:
let's take for instance the number 4 it's a whole number and still a perfect square because when you think of a number from 1to 10, which number when you multiply by itself will give you four apart from 2
Answer:

4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line
Simple. 1.5 as a fraction is 1 & 1/2. If you know how to make fractions decimals, you're set.
