Answer:

A) 5 3/10

B) 785 3/20

Step-by-step explanation:

Hope this helps <3

you find a common denominator and then simplify all fractions to that common denominator. then, you add them up!

2 1/5 + 3 1/10

5 can fit into 10 twice so it becomes...

2 2/10 + 3 1/10 which equals

5 3/10

472 2/5 + 312 3/4

5 times 4 is 20

472 8/20 + 312 15/20

there is a remainder of 3 for the fractions so you put it over 20.

785 3/20

Answer:

3.9

Step-by-step explanation:

Pythagorean theorem:

a^2 + b^2 = c^2

a^2 + 1^2 = 4^2

a^2 + 1 = 16

a^2 = 15

a = sqrt(15)

a = 3.9

Answer a = 3.9 yards

Find the equation of the line that cuts through (0,5) and (1,2)?

MArishka [77]

The equation of the line that cuts through (0,5) and (1,2) is y = -3x + 5

<h3>Solution:</h3>

Given that we have to find equation of the line that cuts through (0,5) and (1,2)

The equation of line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is given as:

$y - y_1 = m(x - x_1)$

Where "m" is the slope of line

Let us first find slope of line

The slope of line is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text{ Substituting } (x_1, y_1) = (0, 5) \text{ and } (x_2, y_2) = (1, 2)$

$m=\frac{2-5}{1-0}=-3$

Thus the required equation of line is:

$y - 5 = -3(x - 0)\\\\y - 5 = -3x\\\\y = -3x + 5$

Thus the equation of line is found
