Answer:
a. answer choice c
b. 20301
Step-by-step explanation:
You first need to understand a formula for finding the sum of consecutive integers starting from one: (m*(m+1))/2, m is the biggest number in the set.
a. The biggest number in your set is 100, so we plug in 100 for m and solve:
100*101/2=50*101=5050
b. Same thing. Use the formula t plug in 201 for m:
201*202/2=201*101=20301
The only reason you have the picture next to your question is to prove the formula (m*(m+1))/2.
Change 5/3 to 15/9. Then add 15 + 17 and put it over 9. 32/9
suppelementary angles are angles that add to 180
remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4
vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3
Answer:
x = 1
y = -3
Step-by-step explanation:
if y = x - 4
then reorganise the first equation
4 (x - 4) = 9x -21
4x - 16 = 9x - 21
5 = 5x
x = 1
It would be 5.5y because y equals 1.
