3 goes in to 40 13 times
7 goes in to 40 5 times
but it is not 13+5 because you do not want to count 21 twice
I believe the answer is 4.50
8. It is divisible by both 32 and 40.
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.
