-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

Answer:
(7x+18)°+(5x-6)° =180° adjacent angles sum up to 180°
7x+5x+18-6=180
12x+12=180

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
Find the following terms (First term, second term, last term)
1 .(x + 1)'2
2. (x + 2)'2
3. (x + 3)'2
4 . (x + y)'2
Answer:
F = FIRST TERM
S = SECOND TERM
L = LAST TERM
Step-by-step explanation:
1- (x+1)² = x²+2x+1
F = x²
S = 2x
L = 1
2- (x+2)² = x² + 4x + 4
F = x²
S = 4x
L = 4
3- (x+3)² = x² + 6x +9
F = x²
S= 6x
L= 9
4 (x+ y)² = x²+2xy +y²
F = x²
S = 2xy
L = y²

Answer:
Below (correct me if i am wrong, mark me as brainliest if right)
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

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.

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.

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.

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)

Since it is asking for the ratio of 6th grade students to all you need to put the amount of 6th grade students first. Then you add the amount of 6th and 5th grade students to get 30. and so the ratio would be 10:30. Hope it helped! :)
