Ji sunn spent $24 at the local farmer’s market. she bought apples that cost $4 per pound and raspberries that cost $6 per pound. which equation can be used to represent the amount of raspberries, r, in terms of apples, a?

r = 4 -2/3 a

Step-by-step explanation:

She spent in total 24 dollars.  So, you can set the equation equal to 24.

? = 24

It costs $4 per pound for apples and $6 per pound for raspberries.  You could represent apples as 4a and raspberries as 6r.  Put this into the equation.

4a + 6r = 24

Now set the equation equal to r.  You have to get r alone on one side.

4a + 6r = 24

(4a + 6r) - 4a = (24) - 4a

6r = 24 - 4a

6r = (24 - 4a)/6

r = 4 - 4/6 a

r = 4 - 2/3 a

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
