Explain how you use estimation to check the reasonableness of a solution to a practical problem.

Mathematics
1 answer:
Oxana [17]3 years ago
3 0

Answer:

Well, one way to use reasonableness is to estimate the answer to see if your answer is an outrageous answer or not. So, looking at your problem, you see that you are multiplying a two hundred something number by 4 and then subtracting 10 from it.

Anita purchased a couch that was priced at $700. She will also have to pay 6% sales tax. How much will she pay in total for the
Zolol [24]

Answer:

$742

Step-by-step explanation:

To solve this, you need to figure out what 6% of 700 dollars is and then add that to 700. The easiest way to find the percentage of a number is to set it up in the equation:

6/100 = x/700  where 6 is the percentage of 700 (out of 100 because you can only get up to 100 percent in this case) and x is 6 percent of 700. when you cross multiply, you get 100x = 4200. Then you divide both sides by 100 to get x by itself. This will give you x = 42 Add this to 700 for 742 as the total amount that will be paid. Sorry if this first half was a little confusing

SOMEONE, PLEASE HELP ME WITH THIS PLSSSS
Stels [109]

Answer:

Step-by-step explanation:

1. You can use the intercepts to graph the line. The graph of 2x + 3y = 12      crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12  crosses the y-axis at (0, 4), so its y-intercept is 4.

2. Point-Slope Form: y - y1 = m(x - x1)

Standard Form: ax + by = c

5x - 2y = 10

-2y = -5x + 10

y = (5/2)x - 5    The slope is 5/2.

y - 2 = (-5/2)(x - 10)

y = (-5/2)x + 25 + 2

y = (-5/2)x + 27      The slope is -5/2.

y = (-5/2)x - 10     The slope is -5/2.
