How do I do this?? :( "Is there only one way to break up a 2-digit number into tens and ones? Explain."

Yes, to break a 2-digit number into tens and ones it is a simple process. To do it you have to take a number, let's say, 56. We can take the 5, because it has one digit to the right of it, we add one 0 to the right of it. Then we do the 6, which has nothing to the right, so we don't put anything there. 50 and 6. 5 tens and 6 ones.

I'm pretty sure that's the only way. If anyone knows otherwise, please post in the comments.

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
