The slope of a line between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by $\frac{y_2 - y_1}{x_2 - x_1}$ . You can think of this as either rise/run or change in y divided by change in x.

Here, the slope is $\frac{6-4}{2-1}$ , which is equal to 2.

1/2 of a bag of candy is skittles, 1/4 is m and m's, and 3/4 of the rest of it are life savers. The rest are sour patch kids. Wh

m_a_m_a [10]

Answer:

6.25%

Step-by-step explanation:

Total = 1 ; as a decimal

1/2 = skittles

1/4 = M&Ms

Skittles +M&Ms = 1/2 + 1/4 = 3/4

Remainder = 1 - $\frac{3}{4}$

Remainder = $\frac{1}{4}$

Sour patch = $\frac{1}{4} *\frac{1}{4} =\frac{1}{16}$

As a percentage , multiply 1/16 by 100 and it becomes 6.25%

Solve 8x + c = k for x.

Scrat [10]

Answer:

$x = \frac{k -c}{8}$

Step-by-step explanation:

$8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\ by\ 8 \ ]\\\\x = \frac{k-c}{8}$

Mr. West is painting his front sidewalk to make it colorful. The total area is 24 square feet. What are the possible dimensions

ryzh [129]

Answer:

All possible dimensions are: 1ft × 24ft = 24 $ft^{2}$ , 2ft × 12ft = 24 $ft^{2}$ , 3ft × 8ft = 24 $ft^{2}$ , 4ft × 6ft = 24 $ft^{2}$ , 6ft × 4ft = 24 $ft^{2}$ , 8ft × 3ft = 24 $ft^{2}$ , 12ft × 2ft = 24 $ft^{2}$ , or 24ft × 1ft = 24 $ft^{2}$ .

Step-by-step explanation:

With the assumption that the sidewalk has a rectangular shape:

Area of a rectangle = length × width

From the question, the total area = 24 $ft^{2}$ .

⇒ length × width = 24 $ft^{2}$

So, all possible combinations are:

i. 1 ft × 24 ft = 24 $ft^{2}$

ii. 2 ft × 12 ft = 24 $ft^{2}$

iii. 3 ft × 8 ft = 24 $ft^{2}$

iv. 4ft × 6 ft = 24 $ft^{2}$

v. 6ft × 4ft = 24 $ft^{2}$

vi. 8ft × 3ft = 24 $ft^{2}$

vii. 12ft × 2ft = 24 $ft^{2}$

viii. 24ft × 1ft = 24 $ft^{2}$
