74-17= 57 because if you subtract 10 from 74, it would be 64, then you need to subtract 7 from 64, which gives you 57.
9+7=16 because 10+7 would be 17, but since 9 is one less than 10, you need to subtract one from 17, which gives you 16.
17+(-30)=(-13) because adding 17 to -30 only brings up -30 to -13, and -30<-13.
-41+24=-17. Same reason as question 3, only different numbers.
-36+(-7)=-43 because adding two negatives together is like subtracting two positives from each other.
14+64=78 because adding 10 to 64 is 74 and 74+4=78.
-53-42=-95 because when you subtract a positive from a negative, it decreases the number even more.
-17-(-62)=45 because -62 is less than -17 and it is being subtracted from -17 so the answer becomes positive.
Hope this helps :)

Answer:
b
Step-by-step explanation:
<span>informal proofs are usually in paragraph form, while formal proofs are numbered, like this:
Given: a=b, b=c
Prove: a=c
1. a=b, b=c 1. Given
2. a=c 2. transitive property
the first line is usually the given, the middle lines are statements which help you get to your proof, and the last line is your proven statement. next to your statements, you have to give reasons why the statement is true, like a=c is proven because of the transitive property</span>
Answer:
A and B
Step-by-step explanation:
This is a geometric sequence, because each number in the sequence is multiplied by another number to get the next number.
The common ratio is 2, because each number is multiplied by 2 to get the next number
1*2=2
2*2=4
4*2=8
Hope this helps! :)
