Answer:
x = -13/4
Step-by-step explanation:
5 - (4x + 7) - 4 = 7
Distribute the minus sign
5 - 4x -7 - 4 = 7
Combine like terms
-4x-6 = 7
Add 6 to each side
-4x-6+6 = 7+6
-4x= 13
Divide by -4
-4x/-4 = 13/-4
x = -13/4
Answer: -13/4 or -3.25 or - 3 1/4

Answer:
- The equation that represent the cost C of renting a car and driving x miles is C = $39.11 + $0.50x
- $130 can travel 181.32 miles
Step-by-step explanation:
From the question, a rental company rents a luxury car at a daily rate of 39.34 $ plus $.50 per mile, that is
$0.50 is added to the initial $39.34 for every mile.
The equation that represent the cost C of renting a car and driving x miles is
C = $39.34 + $0.50x
Now, to determine how many miles 130$ can travel,
we will put C = $100, and determine x in the above equation
$130 = $39.34 + $0.50x
$130 - $39.34 = $0.50x
$90.66 = $0.50x
x = $90.66/$0.50
x = 181.32
Hence, $130 can travel 181.32 miles
2/3 |3x – 6| = 4(x - 2)
solve for the absolute values
Answer: |3x-6| = 0
X = 2
Step-by-step explanation:
2/3 (|3x-6|) = 4x - 8 (divide both sides be 2/3)
3x-6 = (4x-8)/2/3. 4x:2/3 = 12/2 =6x -8:2/3 = - 24/2= - 12
3x-6 = ( 12x - 24 )/2 (multiply both sides by 2)
6x - 12 = 12x -24
12 = 6x
X= 2

What's the difference between like and unlike algebraic expressions
Answer:
In algebra,
• Like terms are terms having the same literal (variable) with same exponents.
Example: 5y + 8y are like terms because they are both "y".
• Unlike terms are terms having the same variable with different exponents or different variable with same exponents.
Example: 4x + 19y are unlike terms because x and y are two different variables with different coefficients.

Step-by-step explanation:
Let's narrow this down, shall we?
It could not be A, because AB and AD are not the same length, AD is a longer line
It is B, because AC an AD seem to be equal lengths
It is C because of B! They are of equal length meaning ACD is a equilateral triangle
it could not be D because it appears to be a scalene triangle and have left as a longer side
It is E because CDE is a isosceles triangle

List all the factors of 21 from least to greatest. Enter your answer below,
using a comma to separate each factor.
Answer:
1,3,7,21
Step-by-step explanation:
-9(y+12)=4(-7y-8)
Solve for y
-9(y + 12) = 4(-7y -8)
Use the distributive property:
-9y - 108 = -28y -32
Add 32 to both sides:
-9y - 76 = -28y
Add 9y to both sides:
-76 = -19y
Divide both sides by-19

A new car worth $28,000 is depreciating in value by $4,000 per year. After how many years will the car's value be
$12,000?
After .. (4 years, which is the answer) the cars value will be at 12,000. i got it correct
After 4 years the value or the cost of car will be $12,000.
Depreciation refers to the decrease in the value of an asset over time due to various factors such as wear and tear, obsolescence, or changes in market conditions.
It is a common concept used in accounting and finance to allocate the cost of tangible assets (such as buildings, machinery, vehicles, etc.) over their estimated useful lives.
Given:
Car cost = $28,000
Depreciation per year = $4,000
Since the car's value is depreciating by $4,000 per year,
Subtract $4,000 from the initial value of $28,000 each year.
= $28,000 - $4,000 - $4,000 - $4,000 - $4,000
= $12,000
Therefore, after 4 years the car is $12,000.

in the figure below the measure of <1=5x°, the measure of <2=y°, and the measure of <3=85°. Find the value of each variable.
(for the first one <1=5x° I found out x=17 so I just need the rest if you can)
Answer:
y=95
Step-by-step explanation:
17x5=85
180-85=95
y=95
Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x and y is 17 and 95, respectively.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.
The measure of ∠1 and ∠3 will be equal since the two angles are vertical angles. Therefore, we can write.
∠1 = ∠3
5x° = 85°
x = 85° / 5
x = 17°
Also, the sum of measures ∠1 and ∠2 will be equal to 180°, this is because the two angles form a pair of linear angles. Therefore, we can write,
∠1 + ∠2 = 180°
5x + y = 180°
Substitute the value of x,
5(17°) + y = 180°
85° + y = 180°
y = 180° - 85°
y = 95°
Hence, the value of x and y is 17 and 95, respectively.
