(a) Let x be the cost of one of Brian's items, then cost of all 4 items bought by Brian will be 4x.

We have been given that Chris bought 3 items that each cost $2.50 more than Brian’s items each cost. The price of each item bought by Chris will be x+2.5. Therefore, the cost of all 3 items bought by Chris will be [tex]3(x+2.5)[/tex].

(b) We are told that Brian and Chris both paid the same amount of money, so we can equate costs of Brian's 4 items and Chris's 3 items as:

[tex]4x=3(x+2.5)[/tex]

Now let us solve for x by distributing 3.

[tex]4x=3x+7.5[/tex]

[tex]4x-3x=7.5[/tex]

[tex]x=7.5[/tex]

Therefore, cost of Brian's each item is $7.5.

Now let us find price of Chris's each item.

[tex]\text{Cost of Chris's each item}=x+2.5=7.5+2.5=10[/tex]

Therefore, cost of Chris's each item is $10.

(c) Now let us check our solution by substituting x=7.5 in [tex]4x=3(x+2.5)[/tex].

[tex]4(7.5)=3(7.5+2.5)[/tex]

[tex]4(7.5)=3(10)[/tex]

[tex]30=30[/tex]

We can see that both Brian and Chris spent equal amount of money that is $30, therefore, our solution is correct.

The answer is $8, sense 12÷3×2=4×2=8.

To find the cost of the store brand cough medicine, which is 2/3 the cost of the national brand priced at $12, you multiply $12 by 2/3, resulting in the store brand costing $8.

The question asks: If one bottle of the national brand of cough medicine costs $12, what is the cost of a bottle of the store brand if it's 2/3 of the national brand? To find the answer, you multiply the cost of the national brand by 2/3, since the store brand costs 2/3 of the national brand's price.

Here's the calculation:

Therefore, the cost of a bottle of the store brand cough medicine is $8.

From the fact that the two horizontal lines are parallel, you can deduce <A=<B

so you can equate the two right-hand sides of the equations:

6x+12=3x+63 and solve for x

3x = 51

x= 17 degrees is the measure <A (and <B as well)

The easy way to do this is:

Since the radius of the second circle is exactly 6 times the radius of the first circle, you could just multiply the circumference by 6:

9.42 x 6 = 56.52!  But let's double-check.

9 x 2 = 18    So, the diameter is 18.

18 x 3.14 = 56.52!     So, 56.52 is the correct answer!

Remark

The formula you should be using is

C = k*r because this is a variation question. There are ways of doing this without solving for k, but it is a good idea to solve for k first.

Answer:

Duration of the tour he planned first is 8 days.

Step-by-step explanation:

Given that a person has 12000 rupees for his daily expenses.

Let x be the number of days.

Then daily expenses per day [tex]=\frac{12000}{x}[/tex]

Given that number of day is increased by 2 more days, that is number of days is x+2.

New daily expense per day [tex]\frac{12000}{x+2}[/tex]

Given that this new daily expenses are 300 less than original.

That is [tex]\frac{12000}{x}-\frac{12000}{x+2}=300[/tex]

              [tex]\frac{12000(x+2)-12000x}{x(x+2)}=300[/tex]

                  [tex]\frac{24000}{x(x+2)}=300[/tex]

                  [tex]x(x+2)=\frac{24000}{300}[/tex]

                    [tex]x^{2}+2x-80=0[/tex]

                    (x-8)(x+10)=0

Answer:

Hey there! The correct answer would be x=-4.

Step-by-step explanation:

To start, you would first need to combine your like terms, terms that are not only raised to the same power but also have the same exact variables. In this case, your like terms are -6x and -11x:

-6x-11x=68 --> -17x=68

Now, divide both sides by -17 in order to isolate your variable term:

-17x/-17 = 68/-17

x=-4

Therefore, your answer would be x=-4.

To check to make sure this answer is right, plug -4 in for x and see if the result is 68=68:

-6(-4)-11(-4)=68

24+44=68

68=68

Remember the formula for time is distance/speed

So 60 would be the distance, or 60m.

Answer:

60 represents the distance

Step-by-step explanation:

Given : y is the time in hours that it takes Micheal to travel to his grandparents house,

            x is his average speed in miles per hour.

To Find: What does the number 60 represents

Solution :

Time= y

x = speed

So, To find distance we will use formula :

[tex]Time = \frac{Distance}{Speed}[/tex]

[tex]y = \frac{Distance}{x}[/tex]  -- A

Given function: [tex]y = \frac{60}{x}[/tex] --B

On comparing A and B

Distance = 60 miles

So, 60 represents the distance .

It is 192.

75 is 100%  so we can write it down as 75=100%.

75=100%  x=256%

CROSS MULTIPLY, proportions.

75/100     X/256

19200/100 equals 192

First, we start with the product

so _________ * _________

Now, the first part of the product is 3+ (a number), n

so (3+n)*___________

And the other side is 8

(3+n)*8

or 8(3+n) =14

Let the number is x

Three more than a number: x  + 3

so the product of three more than a number and eight : 8(x + 3)

Now you can write he equation of the product of three more than a number and eight is fourteen

8 (x + 3) = 14

The surface area of a cylinder with a radius of 6.8 inches and a height of 14.2 inches can be estimated by using the formula including both the curved surface area and the area of the bases, then rounding to compare with provided options.

The surface area of a cylinder can be calculated using the formula S = 2πr(height) + 2πr². Substituting the given radius r = 6.8 inches and height L = 14.2 inches, and using π = 3.14, we estimate the surface area as follows:

S = 2πrL + 2πr² = 2(3.14)(6.8)(14.2) + 2(3.14)(6.8)²

The first term accounts for the curved surface area of the cylinder and the second term accounts for the two circular bases. Calculate each part and sum them to estimate the total surface area. To compare to the provided options, we can round to the nearest whole number.

.1 Option D) Surface area of cylinder 923 in².2 Option (B)√41 3.Option (D) 5/13 4.Option (D) 4. 5Option (c)y = 2x + 1.  6 Option (c)53/72

To find the surface area of a cylinder with radius r = 6.8 inches and height h = 14.2 inches, we use the formula for the surface area of a cylinder:

Surface Area = 2πr(h + r)

First, calculate the lateral surface area:

Lateral Surface Area = 2πrh = 2 * 3.14 * 6.8 * 14.2

Lateral Surface Area ≈ 607.04 square inches

Next, calculate the area of the two circular bases:

Area of bases = 2πr² = 2 * 3.14 * (6.8)^2

Area of bases ≈ 290.66 square inches

Now, add the lateral surface area and the area of the bases to get the total surface area:

Total Surface Area ≈ 607.04 + 290.66 ≈ 897.7 square inches

Comparing this with the given options, the closest estimate is:

D) 923 in²

Using the Pythagorean Theorem

To find the distance between points A and B, assuming a right triangle with legs of length 2 and 3:

Distance = √(2² + 3²) = √(4 + 9) = √13

Answer:

468

Step-by-step explanation:

If the first term of a geometric series and the common ratio are known, then the sum of the infinite series is

                a

s      = --------------

               1 - r

In this particular case we have:

               156

s      = -------------- = 156/(1/3) = 468

               1 - 2/3

The sum of an infinite geometric series with a first term of 156 and a common ratio of 2⁄3 is 468. This is computed using the formula [tex]S = a / (1 - r).[/tex]

The sum of an infinite geometric series can be found by using the formula [tex]S = a / (1 - r)[/tex], where 'S' is the sum of the series, 'a' is the first term of the series, and 'r' is the common ratio. In this case, the first term 'a' is 156 and the common ratio 'r' is 2⁄3.

Substituting these numbers into the formula, we get: S = 156 / (1 - 2/3) . After calculating this expression, we find the sum of the series to be 468. Therefore, the sum of the infinite geometric series with a first term of 156 and a common ratio of 2⁄3 is 468.
