Answer:
67
Step-by-step explanation:
angles on a straight line add up to 180 degrees
so 180 - 127= 53 to get the angle on the bottom left.
60 + 53 = 113
angles in a triangle add up to 180 degrees so 180-113= 67
to double check you should add
60+53+67 if you get 180 then its correct!
hope it helps :)
Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3
The answer is 6 bc i calculated it
Answer:
x+3= 2x when x = 3
3+3 = 2*3
6= 6
They are not equal when x is any other number rather than 3
