The word 'difference' indicates the use of subtraction in a Mathematical sum
The error is that the sum could be 15 - 5y instead of 5y - 15
A subtraction sum does not have the commutative properties, meaning that we cannot do the sum in any order.
A sum 15 - 5y will give a different result with the sum 5y - 15 for the same value of y.
Answer:
P = 2 / 25
Step-by-step explanation:
If we assume that the combination of green and pink means, 1 green and 1 pink, then we can say the following:
P = 1 / 25 + 1 / 25
P = 2 / 25
This is because the squares where green and pink intersect only occurs twice.
Hence, the probability is P = 2 / 25.

Answer:
B must travel at the rate of 10 miles per hour.
The greatest common factor is 2ab
To determine this you need to determine what is divide in both 18 and 8. The only number that can divide in both numbers is 2. Which means they have a common factor/number. And then you continue looking at the expression and see what other numbers or letters are common. The only common thing besides the number is a and b since it’s found in both. There is no c in 18ab.
Hope this makes sense
Please mark as a brainliest (crown) above my comment. Would be much appreciated
