The standard form of a linear equation in general is given by:
[tex]ax+by=c[/tex]
Now we are given the equation :
[tex]4x-\frac{2}{3}y=8[/tex]
In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.
Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.
So multiplying both sides by 3 , we have
[tex]12x-2y=24[/tex]
So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.

A medium can of tomato juice costs $0.92 and contains 46 ounces of tomato juice. A large can of tomato juice costs $3.60 and contains 144 ounces of tomato juice. Which can of tomato juice the lower unit price? How much lower?
Answer:
The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.
Step-by-step explanation:
Medium can: $0.92/(46 oz) = $0.020/oz
Large can: $3.60 / (144 oz) = $0.025/oz
Surprisingly, the medium can price per oz. is lower than that of the large can. The difference is $0.005 per oz.
The medium can of tomato juice has the lower unit price at $0.02 per ounce, which is $0.005 lower per ounce than the large can's unit price of $0.025 per ounce.
To determine which can of tomato juice has the lower unit price, we need to calculate the cost per ounce for each can. For the medium can, we divide the cost by the number of ounces:
Medium can unit price = $0.92 / 46 ounces = $0.02 per ounce
For the large can, we perform a similar calculation:
Large can unit price = $3.60 / 144 ounces = $0.025 per ounce
The medium can has a lower unit price of $0.02 per ounce compared to the large can's unit price of $0.025 per ounce. The difference in unit price is $0.025 - $0.02 = $0.005, or half a cent per ounce.

6. Solve: A chemist needs 30 ounces of 50% hydrochloric acid solution. In her lab, she has some 80% hydrochloric acid solution, some 60% hydrochloric acid solution, and some 40% hydrochloric acid solution. She must use 2 ounces of the 80% solution. How many ounces each of the 40% and 60% solutions must be mixed with the 2 ounces of 80% to obtain the 30 ounces of 50% hydrochloric acid solution she needs?
Final answer:
To prepare 30 ounces of a 50% hydrochloric acid solution, the chemist must mix 17 ounces of the 40% solution with 11 ounces of the 60% solution and 2 ounces of the 80% solution.
Explanation:
The student needs to mix different concentrations of hydrochloric acid to end up with 30 ounces of a 50% solution. We know that 2 ounces of the 80% solution are used, so the remaining 28 ounces must be a mix of the 40% and 60% solutions.
Let x represent the ounces of the 40% solution and 30 - 2 - x, or 28 - x, represent the ounces of the 60% solution. Setting up the equation based on mass of pure hydrochloric acid:
0.80(2) + 0.40(x) + 0.60(28 - x) = 0.50(30)Solving for x:
1.6 + 0.40x + 16.8 - 0.60x = 15-0.20x + 18.4 = 15-0.20x = -3.4x = 17The chemist needs to use 17 ounces of the 40% solution and 11 ounces of the 60% solution, combining them with the 2 ounces of the 80% solution to obtain 30 ounces of 50% hydrochloric acid.
Which inequality represents the graph below?

A total of 336 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
A total of 336 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold then the number of adult tickets sold = 112
Let's denote the number of adult tickets sold as 'A' and the number of student tickets sold as 'S'.
We are given two pieces of information:
1. The total number of tickets sold is 336: A + S = 336.
2. The number of student tickets sold was two times the number of adult tickets sold: S = 2A.
Now, we can use the second equation to substitute the value of 'S' in terms of 'A' into the first equation:
A + 2A = 336.
Combine the like terms:
3A = 336.
Now, isolate 'A' by dividing both sides by 3:
A = 336 / 3.
A = 112.
So, the number of adult tickets sold (A) is 112.
In summary, to find the number of adult tickets sold, we set up equations based on the given information and then solve for the variable representing the number of adult tickets (A).
By substituting the value of 'A' back into one of the equations, we can also find the number of student tickets sold (S).
In this case, 112 adult tickets and 224 student tickets were sold to make a total of 336 tickets.

The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p). If the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds, what is the volume under a pressure of 30 pounds?
a) 45 cubic cm b) 20 cubic cm c) 12.8 cubic cm
Answer : C) 12.8 cubic cm
The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p)
If y is inversely proportional to x then [tex]y=\frac{k}{x}[/tex]
where k is constant of proportionality
v is inversely proportional to p then [tex]v=\frac{k}{p}[/tex]
the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds
Given : v= 24 and p = 16. We need to find out k
[tex]24=\frac{k}{16}[/tex]
Multiply by 16 on both sides
k = 384
Now we find out the volume under a pressure of 30 pounds
[tex]v=\frac{384}{30}[/tex]
[tex]v=\frac{128}{10}[/tex]= 12.8 cubic cm
Under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters, as determined by applying Boyle's law, which states that volume and pressure are inversely proportional in conditions of constant temperature.
The volume (v) of a gas in a container at a constant temperature varies inversely as the pressure (p). This is a demonstration of Boyle's law, which states that pressure and volume are inversely proportional (P = k/V) when temperature is held constant. To find the new volume when the pressure changes, we can set up a proportion based on the original conditions provided: 24 cm³ at 16 pounds pressure. We set the initial volume and pressure as 24 cm³ and 16 lbs, respectively, and then solve for the new volume when the pressure is 30 lbs.
To find the volume under a pressure of 30 pounds, we use the equation:
V1 * P1 = V2 * P2
Where V1 is the original volume, P1 the original pressure, V2 the new volume, and P2 the new pressure. Plugging in our known values:
24 cm³ * 16 lbs = V2 * 30 lbs
Solving for V2, we get:
V2 = (24 cm³ * 16 lbs) / 30 lbs
V2 = 384 cm³ / 30 lbs
V2 = 12.8 cm³
Therefore, under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters.

Nolan deposited $2300 into a savings account for which interest is compound weekly at a rate of 2.12%.
How much interest will he earn after 7 years?
Answer:
The answers is 367.87
Step-by-step explanation:
The interest Nolan will earn after 7 years of time lapse, with the given figures, is $4,863,465 approx.
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that simple interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
For the considered case, the unit of time is weekly.
In 7 years, there can be at least 1 leap year, and at max 2 leap years.
In 7 years, therefore, the number of days are between [tex]6 \times 365 + 366[/tex] and [tex]6 \times 365 + 366+1[/tex] or say in between 2556 and 2557
Since each week has 7 days, therefore, the number of weeks these days will have is approx [tex]\dfrac{2556}{7} \approx 365.14[/tex] (assumed there are 2556 days in 7 years).
This approximates to 365 weeks (integer quantity)
Thus, we get:
Unit of time is weekRate of interest per week = 2.12%Type of interest applied = Compound interestUnits of week for which interest is applied is approx 365Initial amount deposited = $2300Thus, the amount of interest that Nolan will earn is approx:
[tex]CI = P(1 +\dfrac{R}{100})^T - P\\\\CI \approx 2300(1 + 0.0212)^{365} - 2300 \approx 2300 \times 2115.65 - 2300\\CI \approx \$4,863,465[/tex]

a paper coffee filter has a radius of 6 centimeters and a slant of height of 12 centimeters. find the surface area of the filter. round your answer to the nearest whole number.
Final answer:
The surface area of the paper coffee filter with a radius of 6 centimeters and a slant height of 12 centimeters is approximately 339 square centimeters when rounded to the nearest whole number.
Explanation:
Finding the Surface Area of a Coffee Filter
To find the surface area of the paper coffee filter, we need to consider it as a part of a cone because a coffee filter is shaped like a cone with a circular base. The surface area of a cone is calculated by the formula Surface Area = πr(r + l), where r is the radius and l is the slant height. Given that the radius of the coffee filter is 6 centimeters and the slant height is 12 centimeters, the formula should be filled in as follows:
Radius (r) = 6 cm
Slant Height (l) = 12 cm
The calculation will then be:
Surface Area = π x 6 cm x (6 cm + 12 cm)
Surface Area = π x 6 cm x 18 cm
Surface Area = π x 108 cm²
Surface Area ≈ 3.14159 x 108 cm²
Surface Area ≈ 339.29 cm²
Rounding to the nearest whole number:
Surface Area ≈ 339 cm²
The surface area of the paper coffee filter is approximately 339 square centimeters.
Longfield is at an elevation of -144 1/2 feet. Smallville is 4 times farther below sea level than Longfield.
What is the Smallville’s elevation, in feet? The elevation of Smallville is _____feet.
Show me the work please.
The elevation of Smallville is calculated by multiplying the elevation of Longfield by 4. Longfield's elevation is -144 1/2 feet, which is equivalent to -289/2 as an improper fraction. Multiplying this by 4 gives the elevation of Smallville as -578 feet.
Explanation:To find Smallville's elevation, we first take the elevation of Longfield, which is -144 1/2 feet below sea level. Since Smallville is 4 times farther below sea level than Longfield, we have to multiply the elevation of Longfield by 4.
First, convert -144 1/2 to an improper fraction: -144 1/2 = -289/2.
Now, multiply by 4:
(-289/2) × 4 = -289 × 2 = -578 feet
So the elevation of Smallville is -578 feet below sea level.
