Answer:

Step-by-step explanation:

The original number is 3. To solve this you can take your final result (12) and ADD what you subtracted from the product (3) which would then give you the product (15). Next to find your beginning value you can divide by 5.

12+3 = 15

15/5 = 3

a store is having a sale on walnuts and chocolate chips. for 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost

Step2247 [10]

Answer:

Walnuts - $1.25, chocolate chips - $3.25

Step-by-step explanation:

Let walnuts = x, chocolate chips = y

Set a system and solve:

3x + 5y = 20
6x + 2y = 14

Double the first equation and subtract the second one from it:

6x + 10y - 6x - 2y = 40 - 14
8y = 26
y = 26/8
y = 3.25

Find the value of x:

6x + 3.25*2 = 14
6x = 14 - 6.5
6x = 7.5
x = 7.5/6
x = 1.25

last summer, at camp okey-fun-okey, the ratio of the number of boy campers to girl campers was 8:7. If there were a total of 195

Evgen [1.6K]

The ration of boy campers to total campers is 8:15, and the ratio of girl campers to total campers is 7:15. Using this information, we can answer this question by setting up proportions.

For boys:

$\frac{8}{15} =\frac{x}{195}$

*Cross multiply*

15x=1560

*Divide both sides by 15*

x=104

There are 169 boy campers.

For girls:

$\frac{7}{15} =\frac{x}{195}$

*Cross multiply*

15x=1365

91=x

There are 91 girl campers.

Hope this helps!!
