hey guys i really need help with this is for the MOSL in my class how do i find the tax of a question
mylen [45]
How to tax things:

In this case, lets say the state tax is 7%.
Shen you buy something, lets say some shoes. For example lets say the price is 60.99
With the 7% tax, move the decimal point two times to the left: 7 -> .07
Multiply .07 by the total price

60.99 * .07 = 4.27
Then add this amount to the total price
60.99 + 4.27 = 65.26
This is how you tax

A square with sides of length 5 is positioned inside a square with sides of length 7. What is
kow [346]

Answer: 24cm²

Step-by-step explanation:

Let square with length 5cm be represented with A, and square with 7cm be represented with B.

Area of a square is L²

Square A will have an area of 5² = 25cm²

Square B will have an area of 7² = 49cm²

Total area between the two squares will be = Area of Square (B - A)

i.e.

Total Area = 49cm² - 25cm² = 24cm²

If you were to graph the linear equation 4x+6y=−12 on the semester test, you would need to determine the x- and y-intercepts, pl
goblinko [34]

The x intercept is -3, and the y intercept is -2

Step-by-step explanation:

The equation given is 4x+6y= -12

Rewrite the equation in slope intercept form of y=mx +c where c is the y intercept

y=mx+c

6y=-4x-12

y= -4/6 x -12/6

y=-2/3x -2

c= -2

To get x intercept replace value of y in the equation with 0;

y= -2/3 x -2

0= -2/3 x -2

2= -2/3 x

2*3=-2x

6=-2x

6/-2 =x

-3 =x

x intercept is -3

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
larisa86 [58]

Answer: (C) divide by 1

<u>Step-by-step explanation:</u>

when dividing by x - 1, set the expression equal to zero to find the zero.  That is actually what you are dividing by:

x - 1 = 0   ⇒   x = 1

so the number outside of the synthetic division symbol is 1.
