Answer:

11/12

Step-by-step explanation:

Given the expression 1/3 + a = 5/4

Subtract 1/3 from both sides

1/3 + a - 1/3 = 5/4 - 1/3

a = 5/4 - 1/3

a = 15-4/12

a = 11/12

Hence the value of x is 11/12

When Marika bought her house she paid 80% of the purchase price of the house with a loan. She paid the remaining 49,400 of the p
Maurinko [17]

Let

x-----> the purchase price of the house

we know that

1) Marika paid 80\% of the purchase price of the house with a loan

2) Marika paid the remaining \$49,400 of the purchase price with her savings

3) \$49,400 represent the 20\% of the purchase price

so

0.20x=49,400

Solve for x

Divide by 0.20 both sides

0.20x/0.20=49,400/0.20

x=247,000

therefore

<u>the answer is</u>

the purchase price of the house is \$247,000

Aleksandr [31]
Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
