Answer:
Step-by-step explanation:
With the given information, we can write the line equation in slope intercept form.
The slope, m, is -2/5
The Y-intercept, or b, is 100.
Replace m with -2/5 and b with 100.
Answer:
9b-11m
Step-by-step explanation:
add 4b and 5b then add -4m and -7m
Answer:
36
Step-by-step explanation:
Let the original quantity of marbles of the bag be y.
y=36
Answer:
105°
Step-by-step explanation:
The Arc DB = 150°,
If an angle goes from the center of the circle it is the same as the arc. If the angle is inscribed in the circle it is half the arc.
In this case A is inscribed in the circle so its value is half the arc,
The arc is 360 - 150 = 210°
Angle A = 210 / 2 = 105°
A triangle is always 180 degrees so if we add 127+20 we’d get 147. 180-147 is 33 degrees. the missing angle is 33
