Answer:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.
77/15 is the answer to your question
Y intercept is zero.
We can use the points 0,0 and 3,-4
Slope formula
-4 - 0
/
3 - 0
-4/3x is the answer
If you take 90 x 7/8 you get 78.75 min. That's how long he was doing flip tricks. To find the time he's been doing slides, you take the total time (90) minus the amount of flips (78.75) and you get 90-78.75 and the answer is 11.25. If this helped please hit the thanks button :)
a = adult shirts sold
c = children shirts sold
we know the store sold for every 5 "a", there were 3 "c" sold, so we can say that the adult to children shirts are on a 5 : 3 ratio.
We also know that whatever "c" is, adult shirts sold last weekend was 30 more than that, or namely "c + 30".
