The recipe for cereal squares uses the ratio 20 large marshmallows to 3 cups of cereal. The ratio of mini-marshmallows to large
Nadya [2.5K]

The relationships are:

20 large marshmallows = 3 cups cereal

3 mini marshmallows = 1 large marshmallow

 

Therefore if there are 6 cups cereal, so we also get 40 large marshmallows. Since for every 1 large, we need 3 mini, hence:

mini marshmallows = 40 * 3 = 120

I NEED THIS ANSWER ASAP!!!

Let "x" represent the number of units
5x = the number of tomato plants in Inessa's garden
6x = the number of tomato plants in Ralph's garden

the question says that half (1/2 x (5x)) of Inessa's tomato plants are taken from her garden and put into Ralph's garden
this means that Ralph has a total of 850 tomato plants in his garden

using all of this information, we get the following (which we have to solve):
(1/2)(5x) + 6x = 850

when we solve for "x", we find that:
"x" = 100

so, going back to the original statement, if Ralph started out with (6x) tomato plants, and "x" = 100, we have to multiply 6 by 100

doing so gives us our final answer:
Ralph had 600 tomato plants in the beginning
