Answer:
25020, 25920, 25425
Step-by-step explanation:
To find if our number is divisible by 5 the number must end with 0 or 5, divisibility by 9 is if sum of all numbers in number is divisible by 9,
We know B must end with 0 or 5
1. Case 25A20 sum of that number is 9 so if we pick 0 as A we have first number because 9/9=1
We can put A as 9 because 18/9=2
2. Case B = 0, sum is 14 so we need pick A as 4 to get 18.
A. 3:12, reduced is 1:4
b. 4:3
c. 12:19
Answer:
r=20
Step-by-step explanation:
to get rid of the division part, you multiply 6 each side. now you have r+10=30. to solve, now you subtract 10 from both sides. this gives you r=20 :)

Answer:
In any instance.
Step-by-step explanation:
A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.
∠A + ∠B + ∠C = 180°
<u><em>Example:</em></u>
Find ∠C if ∠A = 60° and ∠B = 50°.
60° + 50° +∠C = 180°
∠C = 70°
