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

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.

An expression is shown below:

3(9a + 6b) – (5a + 2b)

Part A:
Simplify the expression shown above.

Part B:
If a represents apples that cost $0.35 each and b represents bananas that cost $0.20 each, what is the total cost based on the expression above?

When buying snacks for her classroom, Ms. Davis bought 4 bags of mixed nuts and 8 bags of pretzels. A bag of pretzels costs $1.50 less than a bag of mixed nuts. She spent $57 for the snacks. The variable is the price of one bag of mixed nuts.

What is the translation of this scenario?
A cost of pretzels = cost of mixed nuts
B cost of pretzels – cost of mixed nuts = 57
C cost of mixed nuts + cost of pretzels = 57
D 57 + cost of mixed nuts = cost of pretzels
