a store is having a sale on chocolate chips and walnuts. for 9 pounds of chocolate chips and 7 pounds of walnuts, the total cost
Ratling [72]

Answer:

The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.

Step-by-step explanation:

9x+7y=51

3x+5y=27

----------------

9x+7y=51

-3(3x+5y)=-3(27)

-------------------------

9x+7y=51

-9x-15y=-81

-------------------

-8y=-30

8y=30

y=30/8

simplify,

y=15/4

9x+7(15/4)=51

9x+105/4=51

9x=51-105/4

9x=(204-105)/4

9x=99/4

x=(99/4)/9

x=(99/4)(1/9)=99/36

simplify

x=2.75

So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.

A survey of 100 people found that 35 people exercise in
Kruka [31]

Answer:

Jim's claim is correct

Step-by-step explanation:

Total survey=100 people

Morning exercise=35 people

Afternoon exercise=45 people

Night exercise=20 people

Morning exercise : Total survey

=35 : 100

Afternoon exercise : Total survey

=45 : 100

Night exercise : Total survey

=20 : 100

Jim's claim is correct because in finding the ratio, one has to relate it with the total people involved in the survey.

Tara's claim however seems to relate one variable with two other variables

Example:

35 : 55

Morning exercise : (morning exercise + night exercise)

35 : (35+20)

35 : 55
