Answer:
42°
Step-by-step explanation:
angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°

c/3+2950=3c/4 the common denominator is 12.
4c+2950*12=3c*3
4c+35400=9c
35400=9c-4c
35400=5c
c=7080 ml =7.08l
5x+13y=-13
13y=-5x-13
y=-5/13x-1
Y-intercept = -1
Slope = 5/13
Answer:
the answer is 7 because 7 *7 is 49
