Answer:

4.5%

Step-by-step explanation:

We know she made 21/22. That means she miss 1 so subtract 21 from 22. We get 1. then divide 22 by 1. So the equation is

$\frac{1}{22}$

which is about 0.454. Then multiply by 100 to get the percent which is 4.54. Round to nearest tenth and we get 4.5%

The weekly salary of a store manager includes a $30 bonus plus the number of hours the manager works multiplied by the managers

gizmo_the_mogwai [7]

Yes. The situation is defined by a linear function.

Solution:

Given, The weekly salary of a store manager includes a $30 bonus plus the number of hours the manager works multiplied by the managers earnings per hour.

Is this situation defined by a linear function?

Yes, the above given situation is defined by a linear function.

Now, let us see the linear equation for above situation

Let the number of hours worked by manager be "x", and cost per hour be "c" and total salary be "y"

Then, total salary is given as,

Total salary = $ 30 bonus + number of hours worked $\times$ cost per hour

$\rightarrow \mathrm{y}=30+\mathrm{x} \times \mathrm{c}\\\\ \rightarrow \mathrm{y}=\mathrm{c} \mathrm{x}+30$

Above equation is a linear equation as "c" is constant ( cost per hour )

Hence, the given situation can be defined by linear function.

What are the steps to answer 6x-2=-4x+2

777dan777 [17]

Answer: $x=2/5$ or $x=0.4$

Simplify the equation to the form

$6x-2=-4x+2$

Move all terms containing x to the left and all other terms to the right

$6x+4x=+2+2$

Simplify left and right side of the equation

$10x=+4$

Divide both sides of the equation by 10 to get x

$10x/10=4/10$

$x=2/5$ or $x=0.4$
