(5-4)-3 = -2. If we move the parenthesis, as is defined by what the associative property is, 5-(4-3) = 4. No matter what, you always approach mathematical equations or expressions using PEMDA. We have to do what's inside the parenthesis first, which is why we end up with 2 different solutions using subtraction.

A shopper payed $530 for an item marked $500 what is the percent of the sales tax

motikmotik

Answer:

First find the amount of tax paid, by subtracting the total amount paid from the cost of the item:

530 - 500 = 30

Now divide the amount of tax paid by the cost of the item:

30 / 500 = 0.06

Multiply by 100:

0.06 * 100 = 6% tax

Segment GH is shown on the graph.

andrey2020 [161]

The coordinates of the point that divides the segment into a 3:2 ratio is (-2.2, -1.2)

<h3>How to determine the coordinate?</h3>

The points are given as:

G = (-4,3)

H = (-1,-4)

Ratio, m : n = 3 : 2

The coordinate of the point is calculated using:

$(x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)$

This gives

$(x,y) = \frac{1}{3 + 2} * (3 * -1 + 2 * -4, 3 * -4 + 2 * 3)$

Evaluate

$(x,y) = \frac{1}{5} * (-11, -6)$

Evaluate the product

(x,y) = (-2.2, -1.2)

Hence, the coordinate of the point is (-2.2, -1.2)

The equation of the line with slope 4 and y -intercept 4 can be written in the form y = m x + b where the number m is: the numbe

VLD [36.1K]

Answer: $m:4; \ b=4$

Step-by-step explanation:

Given

Slope is 4

Y-intercept is 4

For the slope-intercept form of line i.e. $y=mx+b$

$m=\text{slope of line}\\b=\text{Y-intercept of the line}$

So, we can write

$y=4x+4$

$m:4; \ b=4$
