tankabanditka [31]

Answer:

The equation $10x+4=84$ could be used to represent this situation.

Step-by-step explanation:

Given:

Azul bought 10 reams of paper at the store for a total cost of $84 the tax on the purpose was $4.

Now, to find the equation that could be used to represent this situation.

Let the cost of a ream of paper be $x.$

Total reams of paper = 10.

The tax on the purpose = $4.

The total cost = $84.

Now, to write an equation to represent this situation:

$10\times x+4=84$

$10x+4=84$

Therefore, the equation $10x+4=84$ could be used to represent this situation.

Find the distance between the points (10, -4) and (1, 8).

Ivanshal [37]

Answer:

Step-by-step explanation:

Use the distance formula

d = distance

$d=\sqrt{(10-1)^2 + (-4 - (8))^2\\$

Solve the equation to get the following:

$d=\sqrt{9^2 + (-12)^2}$

$d = \sqrt{81+144$

$d=\sqrt{225$

$d = \sqrt{15$
