Answer:

130

Step-by-step explanation:

The two angles add up to 180 since they form a straight line

4y-50 + 3y+55 = 180

Combine like terms

7y +5 = 180

Subtract 5 from each side

7y-5+5 = 180-5

7y = 175

Divide each side by 7

7y/7 =175/7

y =25

The obtuse angle  is greater than 90 degrees

3y+55

3(25) +55

75+ 55

130

Find four consecutive odd integers with a sum of 200
djyliett [7]

Answer:

47, 49, 51, 53

Step-by-step explanation:

I don't know how your teacher wants you to do it, but the formula for odd integers in this case would be (n+1) + (n+3) + (n+5) + (n+7) = 200.

The four odd integers are represented by each set of parentheses. If we find n, we can add 1, 3, 5, and 7 to it to get the four numbers you're looking for.

If we subtract all of the constants from the left side and add all every n, we get 4n = 184. We then divide both sides by 4, and the answer is n = 46.

(n+1) = 47, (n+3) = 49, etc.

Hope this helps!
