11/2 + 3/4 = 22/4 + 3/4 = 25/4
(25/4) / (1/8) = 25/4 * 8/1 = 200/4 = 50 students
Answer:
m<3 = 70 and m<4 = 110
Step-by-step explanation:
<3 and <4 are vertical angles so they add up to 180
(3y + 7) + (5y + 5) = 180
(3y + 5y) + (7 + 5) = 180
8y + 12 = 180
-12 -12
8y = 168
/8 /8
y = 21
find the angle measures:
3(21) + 7
63 + 7
70
5(21) + 5
105 + 5
110
(-9x -1) x (4x+1)
use foil method
-9x * 4x - 9x - 4x - 1
collect like terms by multiplying the -9x and the 4x together, then you add together both -9x and -4x. Then you have your answer below
-36x^2 - 13x - 1
