3(2x-4)+6=30
x=___
Answer:
x = 6
Step-by-step explanation:
Use distributive property: a(b + c) = a*b + a*c
3(2x - 4) + 6= 30
3*2x - 3*4 + 6 = 30
6x - 12 + 6 = 30
6x - 6 = 30
6x = 30+ 6
6x = 36
x = 36/6
x = 6
Answer:
x = 6
Step-by-step explanation:
Simplify 3(2x-4) first: 3 (2x) 3(-4) =
6x - 12+6 = 30
Combine like terms: -12 + 6 = -6
6x - 6 = 30
Add 6 to both sides: 6x = 36
Divide both sides by 6: x = 6
CHECK:
3( 2(6) - 4) +6 = 30
3 (12-4) +6 = 30
3(8) +6 = 30
24+ 6 = 30
30 = 30

1) Solve the equation 7x+5 = 7x-3
Answer: no solutions
7x + 5 = 7x - 3
5 = -3 [ subtract 7x from both sides ]
Since we end up with 5 = -3, a clearly false equation, we conclude that the original equation has no solutions.
i hope this helps! :D
Answer:
empty set

Help me to do this problem System by sustitution.
4) y = -3x - 7
-6x - 2y = 14
Answer:
The system of equations has infinite solutions
Step-by-step explanation:
∵ y = -3x - 7 ⇒ (1)
∵ -6x - 2y = 14 ⇒ (2)
→ Substitute y in equation (2) by equation (1)
∴ -6x - 2(-3x - 7) = 14
→ Simplify the left side
∵ -6x - 2(-3x) - 2(-7) = 14
∴ -6x + 6x + 14 = 14
→ Add the like terms in the left side
∵ (-6x + 6x) + 14 = 14
∴ 0 + 14 = 14
∴ 14 = 14
∵ The variable is disappeared and the two sides of the equation equal
∴ The equation has many solutions
→ That means x and y can be any numbers
∴ The system of equations has infinite solutions

cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.
Given:
Hiroaki says that a constant of proportionality must be a whole number and cannot be a fraction or a decimal.
To find:
The explanation, why Hiroaki is incorrect.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
where, k is the constant of proportionality.
It means, the constant of proportionality is the ratio of two directly proportional variables.
So, constant of proportionality can be any real.
Thus, the statement that a constant of proportionality must be a whole number and cannot be a fraction or a decimal is incorrect.
Hence, Hiroaki is incorrect because constant of proportionality can be any real.

PLEASE HELP!! An alien blob started with a mass of 4 kg and is doubling in size every day. How large will the blob be after 2 weeks?
Answer:
56
Step-by-step explanation:
If a company's Cost of Goods Sold is $158,000 for the period, beginning and ending Inventory balances are $18,000 and $13,000, respectively, and the beginning and ending Accounts Payable balances are $19,000 and $7,500, respectively, what is the amount of the cash paid to suppliers?
Answer:
$164500
Step-by-step explanation:
From the given information:
Decrease in inventory = Beginning inventory - Ending inventory
Decrease in inventory = $18000 - $13000
Decrease in inventory = $5000
Decrease in account payable = $19,000 - $7,500
Decrease in account payable = $11500
The amount of cash paid to suppliers is computed as:
Cost of goods sold $158000
Less: Decrease in inventory - 5000
Add: decrease in accounts payable + 11500
The amount of cash paid back to suppliers: $164500
This question is based on the increment decrement of cost of goods sold.
Therefore, the amount of the cash paid to suppliers is $164500.
Given:
Cost of Goods Sold is $158,000. Beginning and ending Inventory balances are $18,000 and $13,000. The beginning and ending accounts payable balances are $19,000 and $7,500.
We have to calculated the amount of the cash paid to suppliers.
Now, we have to calculated the decrement in inventory.
Decrement in inventory = Beginning inventory - Ending inventory
Decrement in inventory = $18000 - $13000
Decrement in inventory = $5000
Now, we have to calculated the decrement in amount payable.
Decrement in Accounts Payable = Beginning Accounts Payable
- Ending Accounts Payable
Decrement in account payable = $19,000 - $7,500
Decrement in account payable = $11500
The amount of cash paid to suppliers is calculated as:
Amount of cash paid to suppliers = Cost of Goods Sold - Decrement in inventory + Decrement in account payable
Amount of cash paid to suppliers = $158,000 - $5000 + $11500
= $164500
Therefore, the amount of the cash paid to suppliers is $164500.

(3a-2) (3a-2) kindly explain me the steps plus give me solution
Answer:
9a to the power 2 +4 is the answer
Step-by-step explanation:
multiple 3a x 3a u wud get 9a to the power 2
-2 x -2 u wud get = 4
then combine the two and write the answer
Answer:
9a² - 12a + 4
Step-by-step explanation:
Given
(3a - 2)(3a - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
3a(3a - 2) - 2(3a - 2) ← distribute both parenthesis
= 9a² - 6a - 6a + 4 ← collect like terms
= 9a² - 12a + 4
A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor
tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
1. How much money will they collect for selling x floor tickets?
2. How much money will they collect for selling y balcony tickets?
Answer:
We know that x is the number of floor tickets they sell, and each one costs $15, then the amount of money they will get by those sells is x times $15, this is:
x*$15.
And y is the number of balcony tickets they sold, each one of these costs $12, then the total amount of money made in those tickets is:
y*$12.
Then the total amount of money that the band made is:
x*$15 + y*$12
And they want to make, at least, $3,000, then we will have the inequality:
x*$15 + y*$12 ≥ $3000
That can´t really be solved, because we have two variables and only one inequality, but this represents the given situation.

John will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.96 and costs an additional $0.12 per mile driven.
The second plan has an initial fee of $47.96 and costs an additional $0.16 per mile driven. How many miles would John need to drive for the two plans to cost
the same?
II miles
Х
?
So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.
Overall:
1st plan: $58 with driving a 3rd of a mile.
2nd plan: $58 with driving 63 miles.
