Answer:
There are 144 white marbles and 36 blue marbles.
Step-by-step explanation:
Since there are two types of marbles, and there are four times as many white marbles as blue marbles, we divide the amount of marbles by 5. 180 / 5 = 36. 36 times 4 equals 144, therefore there are 144 white marbles. 180 minus 144 equals 36. Therefore there are 36 blue marbles.
Answer:
Number of blue marbles = [tex]36[/tex]
Number of white marbles = [tex]144[/tex]
Step-by-step explanation:
Given information:
- Only blue and white marbles in the bag.
- 4 times more white marbles than blue marbles.
- Total of 180 marbles in the bag.
Variables:
Let [tex]b[/tex] = number of blue marbles in the bag
We can express the number of white marbles as [tex]4b[/tex] since there are 4 times as many white marbles as blue.
- - - -
[tex]b+4b = 180[/tex]
[tex]5b = 180[/tex]
[tex]b=36[/tex]
∴ There are [tex]36[/tex] blue marbles in the bag.
White marbles = [tex]4b[/tex]
[tex]=4(36)[/tex]
[tex]=144[/tex]
∴ There are [tex]144[/tex] white marbles in the bag.
Hope this helps :)
