15 + 20 = 35
35 / 2 = 17.5
Answer:
faster
Step-by-step explanation:
25 in 20 minutes is 25/20 = 1.25 per minute
36 in 30 minutes is 36/30 = 1.20 per minute
The first rate is faster.
Both expressions are equivalent.
To prove that, let x equal a random number. For example, let x=1.
-2+3x and 3x+(-2)
-2+ (3 X 1)= 1.
(3 X 1) + (-2) =1
This question is based on greatest common factor.
There are 45 red buttons and 60 yellow buttons
factors of 45 = 3,5,15
factors of 60 = 2,3,4,5,6,12,15
Hence the highest common factor is 15
Narci can use 15 boxes to divide buttons equally.
She can divide 45 red buttons in 15 boxes by putting 3 buttons in each box.
She can divide 60 yellow buttons in 15 boxes by putting 4 buttons in each box.
