The second one (9.5, 9 3/4, 9 3/8, 9.125)
X= 55° because their is a 90° angle so if you subtract the 35° angle you get 55 as the rest of the 90° angle
Answer:
a = 180 - b + c
Step-by-step explanation:
a + b - c = 180
Move b by subtracting b from both sides.
a - c = 180 - b
Move c by adding c to both sides.
a = 180 - b + c
Therefore a equals 180 - b + c.
First, find out how many markers in total the teacher will need.

Then, find out how many packages the teacher will need by dividing by 8 because that's how many are in each package.

Now because there is a remainder of .375 that tells us that there are not enough markers in 9 packages to give all students 3 each.
She will have to buy an additional package to give every student 3 markers each.
10 Packages are needed.
I’m guessing they are the same shaped, just enlarged. So all you gotta do if so is 18/10 which gives you 1.8 and then 7 x 1.8, this will give you 12.6
So the answer is 12.6, sorry if I’m wrong
