nestor fills a jar with marbles. each marble weighs 1/25 pound .the total weighs of all marbles is 3/5 pound how many marbles are in the jar

Total number of jars will be 15.          

Step-by-step explanation:

Given

The weight of each marble = 1/25 pound

The weight of all marbles = 3/5 pound

To determine

How many marbles are in the jar?

Let 'n' be the total number of jars

The total number of jars can be calculated by dividing the weight of all marbles by the weight of each marble.

Thus,

The total number of jars n = [weight of all marbles] / [weight of each marble]

                                           = [3/5] / [1/25]

                                           = [3 × 25] / [5 × 1]

                                           = 75 / 5

                                           = 15

Thus, total number of jars will be: n = 15

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
