Show your work
Answers
2X - 1 = Y ........................... (2)
From (2),
2X - 1 = Y
Y = 2X - 1
Sub (2) into (1),
(2X-1) - 3 = X + 2
2X - 1 - 3 = X + 2
2X - X = 2 + 1 + 3
X = 6
Sub x=6 into (1),
Y = 2(6) - 1
Y = 12 - 1
Y = 11

WORD PROBLEMS require practice in translating verbal language into algebraic language. See Lesson 1, Problem 8. Yet, word problems fall into distinct types. Below are some examples.
Example 1. ax ± b = c. All problems like the following lead eventually to an equation in that simple form.
Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?
Solution. Every word problem has an unknown number. In this problem, it is the price of the blouse. Always let x represent the unknown number. That is, let x answer the question.
Let x, then, be how much she spent for the blouse. The problem states that "This" -- that is, $42 -- was $14 less than two times x.
Here is the equation:
2x − 14 = 42.
2x = 42 + 14 (Lesson 9)
= 56.
x = 56
2
= 28.
The blouse cost $28.
Example 2. There are b boys in the class. This is three more than four times the number of girls. How many girls are in the class?
Solution. Again, let x represent the unknown number that you are asked to find: Let x be the number of girls.
(Although b is not known -- it is an arbitrary constant -- it is not what you are asked to find.)
The problem states that "This" -- b -- is three more than four times x:
4x + 3 = b.
Therefore,
4x = b − 3
x = b − 3
4 .
The solution here is not a number, because it will depend on the value of b. This is a type of "literal" equation, which is very common in algebra.
Example 3. The whole is equal to the sum of the parts.
The sum of two numbers is 84, and one of them is 12 more than the other. What are the two numbers?
Solution. In this problem, we are asked to find two numbers. Therefore, we must let x be one of them. Let x, then, be the first number.
We are told that the other number is 12 more, x + 12.
The problem states that their sum is 84:
word problem = 84
The line over x + 12 is a grouping symbol called a vinculum. It saves us writing parentheses.
We have:
2x = 84 − 12
= 72.
x = 72
2
= 36.
This is the first number. Therefore the other number is
x + 12 = 36 + 12 = 48.
The sum of 36 + 48 is 84.
Example 4. The sum of two consecutive numbers is 37. What are they?
Solution. Two consecutive numbers are like 8 and 9, or 51 and 52.
Let x, then, be the first number. Then the number after it is x + 1.
The problem states that their sum is 37:
word problem = 37
2x = 37 − 1
= 36.
x = 36
2
= 18.
The two numbers are 18 and 19.
Example 5. One number is 10 more than another. The sum of twice the smaller plus three times the larger, is 55. What are the two numbers?
Solution. Let x be the smaller number.
Then the larger number is 10 more: x + 10.
The problem states:
2x + 3(x + 10) = 55.
That implies
2x + 3x + 30 = 55. Lesson 14.
5x = 55 − 30 = 25.
x = 5.
That's the smaller number. The larger number is 10 more: 15.

Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?
Answers
Answer:
Daniel is 8 years old now.
Step-by-step explanation:
From the word problem we can make the following two equations:
Let "K" be Kevin's age now and let "D" be Daniel's age now, then...
K = 3D
K - 4 = 5(D - 4)
Now we substate the value of K, and get...
K - 4 = 5(D - 4)
3D - 4 = 5(D - 4)
3D - 4 = 5D - 20
3D - 5D = - 20 + 4
- 2D = - 16
D = 8
Therefore Daniel is 8 years old now.

Answers
Answer:
$7875
Step-by-step explanation:
Interest is calculated by the formula: I = Prt
I (interest)
P (principle)
r (rate)
t (time)
Substitute
I = (7000)(0.075)(15)
I = 7875
Thus, our interest is $7875

A new car is purchased for 23700 dollars. The value of the car depreciates at 13% per
year. To the nearest year, how long will it be until the value of the car is 8000 dollars?
Answers
Answer:
the car will be closest to 8000 in year 8. the car would be worth 7778.
Answer:
Year 5
Step-by-step explanation:
If the value decreases by 13% each year that is $3,081 each year (0.13x23,700=3,081)
Year 1: 23700-3081=20619
Year 2: 20619-3081=17538
Year 3: 17538-3081=14457
Year 4: 14457-3081=11376
Year 5: 11376-3081=8295
Year 6: 8295-3081=5214
So, the year would be year 5 and the value of the car would be $8,295
