Answer:
1). 6x +7 = 4x +19
6x – 4x = 19 – 7
2x = 12
x= 12/2
x= 6
2). 3x + 3 = 7x – 5
7x – 3x = 3 +5
4x = 8
x= 8/4
x = 2
3). 39 – 2v = 3v + 4
3v +2v = 39 – 4
5v = 35
v = 35/ 5
v = 7
4). 4n + 6 = 18 – 2n
4n +2n = 18 – 6
6n = 12
n = 12/ 6
n = 2

How is making a perpendicular bisector different to making an angle bisector
Answers
Answer and Step-by-step explanation:
When making a perpendicular line, you take 2 points on a straight line.
- You put the compass on the two points, making marks above and below to be able to draw the line.
When making an angle bisector line, you use the angle and 2 points to make a straight line that will bisect the angle.
- You put the compass on the angle, making an arc from the two lines that join to make the angle. Then, you put your compass on where the arc meets the lines, and make a mark, which you then draw a line through.

A business plan is centered around a circular area of distribution. The plan calls for the radius of the distribution to increase 50 miles per year. The investors have asked that the plan include a reference to the area of distribution based on the number of years in business. These functions model this plan:
Radius in y years: r(y) = 50y
Total area: A(r) = πr2; r in miles
What is A(r(y)), the total area in y years?
A(r(y)) = 50πy2
A(r(y)) = 2,500πy2
A(r(y)) = 50πr2
A(r(y)) = 2,500πr2
Answers
Answer: B. A(r(y)) = 2,500πy2
Step-by-step explanation:
The area would be A(r(y)) = 2,500πy2
What is Area of circle?Area of Circle = πr^2 or πd^2/4 in square units,
Radius: The distance from the center to a point on the boundary is called the radius of a circle. It is represented by the letter 'r' or 'R'. Radius plays an important role in the formula for the area and circumference of a circle, which we will learn later.
Diameter: A line that passes through the center and its endpoints lie on the circle is called the diameter of a circle. It is represented by the letter 'd' or 'D'.
given:
Radius in y years: r(y) = 50y
Total area: A(r) = πr2; r in miles
Now, area of circle
=πr²
=π(50y)²
=2500y²π

The number of days the book was late is 14 days.
The given parameters include;
let the number of days late before she returned the book = xThe following algebraic equation will be set to calculate the number of days the book was late before it was returned;
[tex]0.25(4) + (x - 4)0.3 = 40\\\\[/tex]
simplify the equation as follows;
[tex]1 + 0.3x - 1.2 = 4\\\\[/tex]
collect similar terms together;
[tex]0.3x = 4.2\\\\[/tex]
divide through by 0.3
[tex]x = \frac{4.2}{0.3} \\\\x = 14 \ days[/tex]

Find how many days late was her book
The total days late is 14 days
charges per day for first 4 days = $0.25
charges per day for the remaining days = $0.30
Total amount Annika paid = $4.00
let x = number of days of the remaining days
Total amount paid = Amount paid for first 4 days + amount paid for remaining daysAmount paid for first 4 days = $0.25 × 4
= $1
Amount paid for remaining days = 0.30 × x
= 0.30x
Total amount paid = Amount paid for first 4 days + amount paid for remaining days
4 = 1 + 0.30x
4 - 1 = 0.30x
3 = 0.30x
x = 3/0.30
x = 10 days
Total days late = 4 days + 10 days
= 14 days
