Answer:
140 degrees
Step-by-step explanation:
Due to ∠3 and ∠4 being vertical angles (they are across from one another) their measures are the same, therefore:
⇒ m∠3=m∠4
and since their measures are given in terms of x to find x just substitute:
⇒ x+30=2x-80 ⇒ x=110
We substitute x in m∠3=x+30 and find that m∠3=140 degrees
Answer:
The equation in slope-intercept is: y= 1/2x + 6.
I think it's 30,000 because 8 rounds to 10 so 28 rounds to 30
Answer:
See below
Step-by-step explanation:
Lets do the long division:-
- x - 5
-------------------
x + 4 ( -x^2 - 9x - 20
-x^2 - 4x Subtract:-
------------
-5x - 20
-5x - 20
The quotent is -x - 5 with no remainder so the graph will be a straight line with negative slope of -1, and y-intercept at (0, -5).
2(21x − 7) + 4(3x + 2) = 6(2x + 9) + 3
42x - 14 + 12x + 8= 12x + 54 + 3
54x - 6= 12x + 57
54x=12x + 63
42x=63
x= 63/42
x= 3/2
