My question is what is the answer to this question when
7p+5 when p=12

240 soldiers were transferred to the other camp. Let's assume the number of soldiers transferred to the other camp is "x." we can solve for the unknown variable representing the number of soldiers transferred.

Initially, the food provision was planned for 800 soldiers for 35 days. This means that the total food supply is equal to 800 soldiers multiplied by 35 days, which gives us a total of 28,000 soldier-days of food.

After some soldiers were transferred, the remaining soldiers had enough food to last for 50 days. So the food supply for the remaining soldiers can be calculated as the product of the number of remaining soldiers and the number of days, which gives us (800 - x) * 50 soldier-days of food.

Since the amount of food remains the same, we can set up the following equation:

\(28,000 = (800 - x) * 50\)

Now, let's solve this equation to find the value of x, representing the number of soldiers transferred to the other camp:

\(28,000 = 50 * 800 - 50x28,000 = 40,000 - 50x50x = 40,000 - 28,00050x = 12,000x = 12,000 / 50x = 240\)

By setting up the equation based on the total food supply for the initial and remaining soldiers, we can solve for the unknown variable representing the number of soldiers transferred. In this case, 240 soldiers were transferred to the other camp.

Answer:

$2.

Step-by-step explanation:

What the question is asking you to do, is to make an algebraic expression. First, we will start with what she had, which was $32. Next, it says that "after 6 rides, she had $20 left." The words "left" or "left over" imply subtraction in an equation. So, now we will put together what we have.

32 - 6r.

To explain the r, in algebra letters called variables represent mystery numbers that you have to solve and figure out. Anytime that you see a variable next to a number, it means you need to multiply the mystery number by the base number, which is 6 in this situation. We will use the letter r in this situation for rides. Now we will fit the 20 into the equation. So, we will now solve and complete the equation.

32 - 6r = 20.

First, subtract 32 from both sides of the equation to cancel out the +32. Doing this will balance the equation.

32 - 6r = 20

-32         -32

             -12

Because of the subtraction sign in front of the 6, it is now negative. We now also need to cancel out that -6 to find the answer of r.

- 6r = -12

-6      -6

And, a negative divided by a negative equals a positive, so:

r = 2.

Step-by-step explanation:

all you do is add the numbers to get the total.

The result suggests that the mean wake time might have really reduced since the values barely fall above 100 min as in before treatment with a high degree of confidence. thus , the drug is effective.

Confidence interval is written in the form as;

(Sample mean - margin of error, sample mean + margin of error)

The sample mean represent x , it is the point estimate for the population mean.

Margin of error = z × s/√n

Where s = sample standard deviation = 21.8

n = number of samples = 17

Now the population standard deviation is unknown and the sample size is small, hence, we would use the t distribution to find the z score

then the degree of freedom, df for the sample.

df = n - 1 = 17 - 1 = 16

Since confidence level = 99% = 0.99, α = 1 - CL = 1 – 0.99 = 0.01

α/2 = 0.01/2 = 0.005

Therefore the area to the right of z0.005 is 0.005 and the area to the left of z0.005 is 1 - 0.005 = 0.995

the t distribution table, z = 2.921

Margin of error = 2.921 × 21.8/√17

= 15.44

The confidence interval for the mean wake time for a population with drug treatments will be; 90.3 ± 15.44

The upper limit is 90.3 + 15.44 = 105.74 mins

The lower limit is 90.3 - 15.44 = 74.86 mins

Answer:

Step-by-step explanation:

First, we need to find the difference between the price that he sold the shares for and the price that he bought them at: (67.68-60.65) = 7.03

That means that there was a gain of $7.03 per share for Archie.

That being said, since Archie bought 100 shares, we can multiply that number by 100 to find the total gain from selling the shares:

(7.03x100)= 703

The answer then is:

Archie gained $703 from selling all of his shares.

Answer:

x is equal to -34/16

Step-by-step explanation:

Hey there!

In order to solve for x, we need to first simplify everything

After simplifying, it will look like this:

\((4x^2+14x+16)-7x+14=4x^2-4-9x\)

Now you can simplify by combining like terms

\(4x^2+7x+30=4x^2-9x-4\)

You can cross out \(4x^2\) from both sides and then simplify even more by again combining like terms

\(16x+34=0\\16x=-34\\x=-34/16\)

So x is equal to -34/16

To solve the given equation, let's simplify and expand both sides:

\(\displaystyle\sf (2x+1)(2x+6)-7(x-2)=4(x+1)(x-1)-9x\)

Expanding the brackets:

\(\displaystyle\sf (4x^{2}+13x+6)-7x+14=4(x^{2}-1)-9x\)

Simplifying further:

\(\displaystyle\sf 4x^{2}+13x+6-7x+14=4x^{2}-4-9x\)

Combining like terms:

\(\displaystyle\sf 4x^{2}+6x+20=4x^{2}-9x-4\)

Subtracting \(\displaystyle\sf 4x^{2}\) from both sides:

\(\displaystyle\sf 6x+20=-9x-4\)

Bringing all the variables to one side and the constants to the other side:

\(\displaystyle\sf 6x+9x=-4-20\)

\(\displaystyle\sf 15x=-24\)

Dividing both sides by \(\displaystyle\sf 15\) to solve for \(\displaystyle\sf x\):

\(\displaystyle\sf x=-\frac{24}{15}\)

Simplifying the fraction:

\(\displaystyle\sf x=-\frac{8}{5}\)

Therefore, the solution to the equation is \(\displaystyle\sf x=-\frac{8}{5}\).

The fractional part of 70/28 is 35/14 i.e., 2.5

Percentage:

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100

28 of 70 can be written as:

=> \(\frac{28}{70}\)

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

\(\frac{28}{70}\) × \(\frac{100}{100}\)

=> (28 × 100) /70 ×\(\frac{1}{100}\)

=> 40/100

The translation direction is 5 units to the left.

To determine the translation direction and number of units, we can compare the original coordinates of point Q (Q(5, 4)) with the new coordinates of Q' after the translation (Q'(0, 4)).

By comparing the x-coordinates, we can see that the x-coordinate of Q' is smaller than the x-coordinate of Q, which means the triangle was translated to the left.

By comparing the y-coordinates, we can see that the y-coordinate of Q' is the same as the y-coordinate of Q, which means there was no vertical translation.

Therefore, the translation direction is 5 units to the left.

To find the number of temperatures in the set, we can divide the sum of the temperatures by the mean temperature.

Number of temperatures = Sum of temperatures / Mean temperature

In this case, the sum of temperatures is given as 2,516 and the mean temperature is given as 74 degrees Fahrenheit.

Number of temperatures = 2,516 / 74

Calculating the division:

Number of temperatures ≈ 34.05

Since we cannot have a fraction of a temperature, we need to round the result to the nearest whole number. Therefore, there are approximately 34 temperatures in the set.

2 = |3x|

−4/5x + 1/25 = 0

3x = 4 − x

Answer

Step-by-step explanation:

This has to be equal to something in order to solve it. I'm going to guess that it is equal to 0

(3x-15)(2x+7) = 0

That means that

3x - 15 = 0

3x = 15

x = 15/3

x = 5

or

2x + 7 = 0

2x = - 7

x = -7/2

x = - 3.5

The only other thing I can think of that this could equal is multiplying the two binomials together.

3x * 2x = 6x^2

3x*7 = 21x

-15*2x = - 30x

-15 * 7 = - 105

6x^2 - 7x - 105

But that does not solve for x.
