Aleks [24]

Answer:

The percentage people surveyed like to the new product is 44%.

Step-by-step explanation:

Given:

Company took a survey about its new project, hundred people surveyed, 44 liked the new product.

Now, to find the percentage of the people surveyed like to the new product:

(3x-1)+31+90=180<br> Find x

AysviL [449]

<h2> SOLVE FOR X</h2>

ANSWER:

<h3> x = 20</h3>

<u>Add −1 and 31 to get 30.</u>

$\large\color{orange}{ \tt{3x+30+90=180}}$

<u>Add 30 and 90 to get 120.</u>

$\large\color{orange}{ \tt{3x+120=180}}$

<u>Subtract 120 from both sides.</u>

$\large\color{orange}{ \tt{3x=180−120}}$

<u>Subtract 120 from 180 to get 60.</u>

$\large\color{orange}{ \tt{3x=60}}$

<u>Divide both sides by 3.</u>

$\large\color{orange}{ \tt{x=60/3}}$

<u>Divide 60 by 3 to get 20.</u>

$\large\color{orange}{ \tt{x = 20}}$

Determine the rate of change of the linear equation. 2x/5-3y/2=7

Andrew [12]

Answer:

4/15

Step-by-step explanation:

2x/5-3y/2=7

<em>Multiply all terms by the lcd.</em>

10(2x/5) + 10(-3y/2) = 10(7)

<em>Cross cancel.</em>

2(2x)+ 5(-3y) =70

<em>Simplify.</em>

4x -15y = 70

<em>Subtract 4x from both sides.</em>

-15y = -4x +70

<em>Divide by -15 on both sides.</em>

y= 4/15x -24/3
