Solve for x: (5 points) (-6/5)x -4 = -46 a. 23 b. 35 c. −23 d. −35

1 answer:

8 0

Hi there! The answer is B. 35.

$( - \frac{6}{5} )x - 4 = - 46$
Add 4 to both sides.

$( - \frac{6}{5} )x = - 42$
Divide by -1.

$\frac{6}{5} x = 42$
Divide by 6/5

$x = 35$
Therefore, the answer is B. 35.
~ Hope this helps you!

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

<em>Hence, Jill drove 72 miles</em>

Which finds the solution to the equation represented by the model below? 2 x tiles = 1 x tile and 3 positive 1 tiles removing 1

IRINA_888 [86]

The statement which therefore finds a solution to the given model is; Removing 1x-tile from each side.

<h3>Equation model</h3>

The model represented by the statement;

2 x tiles = 1 x tile and 3 is;

<em>2x = 1x + 3.</em>

In essence, The mathematical solution to the model which involves solving for x is;

2x -1x = 1x + 3 -1x; so that we have;

x = 3.

The statement which therefore finds a solution to the given model is;

Removing 1x-tile from each side.
