Solve the proportion 45=28x using two different methods. Explain each method

Answers

Answer:

x=45/28  

Step-by-step explanation:

1.

You need to isolate the variable by dividing each side by factors that don't contain the variable. In this case, the variable would be x. Isolate x and divide it by the two factors. You have your answer.

2.

Another way you could do it is by using a proportion. You would need to set up your proportion by dividing both sides of the equation by the same term and then simplify the whole problem. You will still be left with a variable.

Potatoes are on sale at both Grocery Mart and Baldwin Hills Market. At Grocery Mart, a 5 lb. bag of potatoes cost $2.85, and at Baldwin Hills Market a 7 lb. bag of potatoes costs $4.20. Which store offers the better price per pound for potatoes?
Grocery Mart price per pound potato:
Baldwin Hills price per pound potato:
Which store offers the better price per pound on potatoes? How do you know? What is the difference in the price per pound? Please explain your answer and do this step by step
HELP ME PLS

Answers

Answer: Grocery Mart: $1.75 per 1lb

               Baldwin Hills Market: $1.67 per 1lb

Step-by-step explanation:

For the first one what you wanna do is divide 5 by 2.85 which then you will get a decimal that is infinite so then you round to the nearest tenth

A: $1.75 per 1lb

    Grocery Mart

For the second one you wanna do the same thing and divide 7 by 4.20 and then the answer would be an infinite number of 6 so then you round to the nearest tenth again.

A: $1.67 per 1lb

    Baldwin Hills Market

The best deal is Baldwin Hills Market since its cheaper per pound

The difference between Baldwin hills market and grocery mart is 8 since 1.75 - 1.67 is 8.

Grocery Mart has a better price for potatoes

Grocery Mart: $0.57 per lb
Baldwin Hills Market: $0.60 per lb

To get the answer you set it up as fractions
5/2.85=1/x (5lb over $2.85) (1 lb over x). X is our missing number. A quick way to get the answer is do 2.85 times 1 = 2.85 then divide that number by 5 and you get x=0.57
Do the same with 7/4.20, 4.2 times 1 equals 4.2 then divide by 7 and you get x=0.6

I hope this explains everything :)
