Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week
Answer:
A = w + 0.20m
Step-by-step explanation:
Step 1
We find the equation for the total amount spent in a week
The total amount to rent the van in a week = A
Weekly fee = w
Number of miles = m
Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is
A = w + 0.20m

When doing decimals, what does a dot over a number mean? For example, take 24.671, but theres a small dot over the numbers 6 and 1. What do I do and what does it mean?
Answers
Step-by-step explanation:
The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.
In this example;
24.671
The numbers before the point, 24 is the whole number
The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.
Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

What is the area, in square meters, of the shaded region in the diagram?
Answers
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2

Jenna bought enough lattes for all her friends. Each latte was $3.50
and she gave the barista a $20 bill, who then gave her back $2.50
in change. Write an equation modeling this, with x as the cost per late
How many lattes did she buy?
Answers
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Step-by-step explanation:
y=3.5x (cost function where y is cost and x is the number of lattes)
20-2.5=3.5x
17.5=3.5x
5=x
So she bought 5 lattes.

Answer:
1. 8x + 3y - x - 2y
= 8x - x + 3y - 2y
= 7x + y
2. 3n - 7n - 2n + x + 8x
= 3n - 9n + 9x
= - 6n + 9x
3. 2r - 5n + 9y - 3r + n
= 2r - 3r - 5n + n + 9y
= -r - 4n + 9y
4. 12y - 6x + 5y - 3n
= 12y + 5y - 6x - 3n
= 17y - 9n
5. - 13n + 4n - r
= -9n - r
6. 7xy - 8x + 6xy - y
= 7xy + 6xy - 8x - y
= 13xy - 8x - y
7. - 14r - 10n - 3r - 9n
= -14r - 3r - 10n - 9n
= - 17r - 19n
8. 6r + 9r - 2r - 13n
= 6r + 7r - 13n
= 13r - 13n
9. n + r + x - 3x +4r
= n + r + 4r + x - 3x
= n + 5r - 2x
10. 15y - 7x + 9z + 4z - 3x

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
Answers
Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)
