1. The ratio of red marbles to blue marbles
in a bag is 2 to 5. If there are 60 more
blue marbles than red marbles in the
bag, how many marbles are there all
together?

Respuesta :

Answer:

84

Step-by-step explanation:

Cross multiply to solve for the red marbles

Let x = the number of red marbles

2/5 = x/60

Cross multiply

2(60)/5 = x

x = 24 which is the number of red marbles.

60 blue plus 24 red = 84 total marbles.
