Answer:
The answer is 4/10
Step-by-step explanation:
If you add all marbles in both bags it equals 40. There are 10 pink marbles in both so 40 / 10 is 4 and the denominator would be 10. 4/10
If D is the center of the circle, ∠ADB = 70°, as that is where the arc gets its measure.
If D is on the circle and not on the arc, ∠ADB = 35°, half the measure of the arc's central angle.
If D is on arc AB, then ∠ADB = 145°, half the measure of the corresponding central angle.
If D is inside or outside the circle (and not one of the above), we need to know more about the measures of arcs intercepted by lines AD and BD.
Answer:
y = 1
Step-by-step explanation:
y - 3 = 7 (y - 9/7)
y - 3 = 7*y + 7*-9/7
y - 3 = 7y - 9
y - 7y = 3 - 9
-6y = -6
y = -6/-6
y = 1
probe:
1 - 3 = 7(1 - 9/7)
-2 = 7*-2/7
