Answer:
15
Step-by-step explanation:
let r represent red marbles then white = 2r + 5 and total is 20, thus
r + 2r + 5 = 20 ( subtract 5 from both sides )
3r = 15 ( divide both sides by 3 )
r = 5 ← number of red marbles
Thus number of white = 20 - 5 = 15
Answer:
x = 9
Step-by-step explanation:
The angles in red are equivalent and the triangle is isosceles.
This means the sides with lengths 12 and x + 3 are equivalent.
x + 3 = 12
x + 3 - 3 = 12 - 3
x = 9
