Its three because three divided by two times three plus equal 13.5
m<1 = m<4 by vertical angles theorem
3x + 10 = 4x - 15
-1x = -25
x = 25
m<1 + m<7 = 180 if parallel alternate interior angles supplementary
3x + 10 + m<7 = 180
3(25) + 10 + m<7 = 180
75 + m<7 = 180
m<7 = 105°
Hope this helps! ;)
Answer:
24 red marbles
Step-by-step explanation:
Ok, why not let R = number of red marbles.
The first sentence says:
3 * R = (33 and 1/3) % * R + 64
or
3R = 100/3 %*R + 64
3R = (1/3)*R + 64
9R = R + 192
8R = 192
R = 24 red marbles
