Answer:
$3.05
Step-by-step explanation:
Backpack=$18.70
6 note books=x
Sales tax=6%
Total cost=$39.22
18.70+x+0.06(18.70+x)=39.22
18.70+x+1.122+0.06x=39.22
19.822+1.06x=39.22
1.06x=39.22-19.822
1.06x=19.398
x=19.398/1.06
=18.3
x=$18.3
6 books=$18.3
Each book cost=18.3/6
=$3.05
In the right angled triangle ACD shown with isosceles triangle ABC and ADC, AB = AC = AD
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
A triangle is a polygon that has three sides and three angles. Types of triangles are<em> isosceles, equilateral and scalene</em>.
In the diagram shown:

It’s called a rate
Answer:
Step-by-step explanation:
It is assumed the width of the street is the distance between the opposite buildings.
<em>See the picture attached</em>
<u>It comprises of two parts: </u>
<u>Using Pythagorean theorem, lets find the value of x:</u>
- x² + 15² = 17²
- x² = 289 - 225
- x² = 64
- x = 8 m
<u>Same rule for y:</u>
- y² + 8² = 17²
- y² = 289 - 64
- y² = 225
- y = 15 m
<u>The width of the street (road) is:</u>
Answer:
Yes, she is right.
in y = m*x + b
b is the initial value or the y-intercept.
If you know that a line has a slope of m <em>(was not given)</em> and a y-intercept of 7, what is the equation for that line in slope-intercept form?
y = m*x + 7
