Answer:
45 green beads
.
Step-by-step explanation:
Let the number of red beads be 'x'
Given that, Carrie has 3 times as many green beads as red beads
Number of green beads = 3 times number of red beads
Number of green beads = 3x
She 2 as many blue beads as green beads
Number of blue beads = 2 times the number of green beads
Number of blue beads = 2(3x) = 6x
She has 150 total
Therefore,
Number of red beads + Number of green beads + Number of blue beads = 150
x + 3x + 6x = 150
10x = 150
x = 15
Thus, number of green beads = 3x = 3(15) = 45
Thus there are 45 green beads
I hope this helps
The question requires finding total green beads she has
There are 45 green beads
let
number of red beads = x
number of green beads = 3x
number of blue beads = 2(3x)
Total beads = 150
Total beads = red beads + green beads + blue beads
150 = x + 3x + 2(3x)
150 = 4x + 6x
150 = 10x
divide both sides by 10
x = 150/10
x = 15
Therefore,
number of red beads = x
= 15 beads
number of green beads = 3x
= 3 × 15
= 45 beads
number of blue beads = 2(3x)
= 2(3 × 15)
= 2(45)
= 90
