EVALUATE THE WORD PROBLEMS

andrezito [222]

Another effective strategy for helping students improve their mathematics performance is related to solving word problems. More specifically, it involves teaching students how to identify word problem types based on a given problem’s underlying structure, or schema. Before learning about this strategy, however, it is helpful to understand why many students struggle with word problems in the first place.

Difficulty with Word Problems

Most students, especially those with mathematics difficulties and disabilities, have trouble solving word problems. This is in large part because word problems require students to:

Point B has coordinates (2,1). The x-coordinate of point A is negative 1. The distance between point A and point B is 5 unit

Gwar [14]

Answer:

A = (-1,5) or (-1,-3)

Step-by-step explanation:

A = (-1,y) B = (2,1)

(Distance from A to B) = √[(-1-2)² + (y-1)²] = 5

=√[9 + y² - 2y + 1] = 5

Squaring on both sides

= y² - 2y + 10 = 25

=y² - 2y -15 = 0

= (y-5)(y+3) = 0

y = 5 or -3

Therefore, A = (-1,5) or (-1,-3)

to make a shade of plant called Jasper Green, Mix 4 quarts of green paint with 2/3 cups of black paint. how much green paint sho

r-ruslan [8.4K]

Answer

24 quarts of green paint should be mixed with 4 cups of black paint.

That is (96 cups)

Step by step explanation

Jasper Green mix 4 quarts of green paint with 2/3 cups of black paint.

Let's convert 4 quarts into cups.

1 quart = 4 cups

4 quarts = 16 cups

Here mix 16 cups of green paint with 2/3 cups of black paint.

Let's use the proportion

Green paint Black paint

16 2/3

x 4

16/x =2/3 divided by 4

$\frac{16}{x} = \frac{2/3}{4}$

Cross multiplying, we get

16*4 = 2/3 x

64 = 2/3 x

x = 64/(2/3)

x = 64 * 3/2

x = 192/2

x = 96 cups

96 cups of green paint should be mixed with 4 cups of black paint.

We can covert 96 cups into quarts by dividing by 4

96/4 = 24 quarts

24 quarts of green paint should be mixed with 4 cups of black paint.

Thank you.
