that would help you determine the cost
of one book.
Help!
Answers
Answer:
5x+8=26.50
Step-by-step explanation:
Because the books are equal in price, we can use x to represent the price of the books and 5 to represent the amount, so it would be written as 5x. Then we add 8 because that's the price of the one DVD. It tells the total is 26.50, so the full equation written would be 5x+8=26.50

a) The length of a rectangle is 3 m longer than its width and the area of the rectangle is 108 m². Find its length.
Answers
Area is (width)(Length) = (width)(width+3)
W
----------
| |

| | L = w+3
| |
| |
-----------
A = (w+3)(w)
A = w2 + 3w = 108.
(Problem states that area is 108 sq in)
Need to solve this quadratic equation
w2 + 3y - 108 = 0
Factor:
(w - 9) (w + 12) = 0
So
w - 9 = 0. or. w + 12 = 0
Solve these and get
w = 9. or. w = -12
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 9 inches
Length = 12 inches

A car travels 180 miles in 3 hours and 45 minutes. How many miles does it travel per hour?
Answers
Answer:
48 miles per hour
Step-by-step explanation:
first I would convert everything to hours It makes it easier. That means that 3 hours and 45 mins becomes 3 3/4 hours So now you have 180/3.75 = the rate. To find the answer, simply divide that, and you get 48. 48 miles per hour

d = vt
where:
v = speed
d = distance
t = time
Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.
If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.
180 / 2 = 90
The new distance so far is 90 miles.
But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.
90 * 3 = 270
The car travels 270 miles.

Answer:
C.) y = 5/4x - 4
Step-by-step explanation:
Points: (0,-4) and (4,1)
m = y2 - y1/x2 - x1
m = 1 - (-4)/4 - 0
m = 1 + 4/4
m = 5/4
Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)
y - y1 = m(x - x1)
y - 1 = 5/4(x - 4)
y - 1 = 5/4x - 5
y = 5/4x - 5 + 1
y = 5/4x - 4
Pam used the following process to find the y intercept of the line described by the equation 2y-y=11.
According to Pam's method, which expression gives the y-intercept of the line described by the equation ax+by=c?
a. -a/b
b. b/a
c. -b/c
d. c/d
Answers
Answer:
c/bStep-by-step explanation:
Given the expression ax+by = c, the y intercept of the line occurs at when x = 0
Substitute x = 0 into the expression and get the value of y
ax+by = c
a(0)+by = c
0+by = c
by = c
divide both sides by b
by/b = c/b
y = c/b
Hence the y intercept of the line occurs at y c/b

Answer:
B
Step-by-step explanation:
Point B is located 6.5 tenths left of -8.
Answer:
Point B
Step-by-step explanation:
If you count 5 steps backward from -8, you land in the direct middle of -9 and -8. You can also count 5 steps forward from -9, but it doesn't change that the number represented is -8.5. Now focus on the distance from -8.5 to -9 (because between that distance are the points that we might be using). You repeat the same process used above, so if you half the distance between -8.5 and -9 then you'll get -8.75. As we can see, Point A is the closest to -8.75 compared to Point B. It wouldn't make sense to choose Point B because as we mentioned before, Point A is now most certainly not -8.65. Point B represents that number the best.

Answers
Answer:
Step-by-step explanation:
Find the LCM of 30 & 20
30 = 2 * 5 * 3
20 = 2 * 2 * 5
LCM = 2 * 3 * 2 * 5 = 60
60 minutes = 1 hour
So, again at 10am both will leave at the same time
Answer:
11 am.
Step-by-step explanation:
That would be the LCM of 20 and 30 which is 60 minutes.
So the nexrt time will be 10.00 + 60 mins
= 11.00 am.
How do you find the run between two points? Can the rise be negative? Explain
Answers
Answer:
Step-by-step explanation:
To find run between two points, you will use the x-values.
For example, (2,3) and (4,5).
Your equation for slope is m=[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
To find the run of these two numbers, you will subtract the second x value from the first x value.
Your answer would be 2 for the run.
It is possible for the rise to be negative if the y value of the point is greater in the first point than the second.
Example:
points (2,8) and (5,1)
1 - 8 would equal -7.

This formula is used to calculate the weekly pay of a letting agent. Weekly pay = basic pay + number of houses rented x bonus The basic pay is £400 and a bonus of £75 is paid for each house rented. Mrs Lewis rents out 5 houses in one week. Calculate her pay.
Answers
Answer:
£775
Step-by-step explanation:
From the question, it was given that:
Weekly pay = basic pay + number of houses rented x bonus
This expression can be used to determine the amount of money being paid to the agent every week.
When basic pay = £400, bonus = £75, and the number of house rented = 5.
Then,
Weekly pay = 400 + 5(75)
= 400 + 375
= 775
Weekly pay = £775
The amount of money paid to Mrs Lewis every week is £775.
