Answer:

x=5

Step-by-step explanation:

We can write ratios to help us solve

4x            12 +3

---------- = ------------

3x+1                 12

Using cross products

4x*12 = (3x+1) * (15)

48x = 45x +15

Subtract 45x from each side

3x =15

Divide by 3

3x/3 =15/3

x=5

Answer:

[tex]4x - 13[/tex]

Step-by-step explanation:

Given

Represent the number with x

Required

Translate the statements to expression

First, we need to get triple of x:

[tex]Triple\ of\ x= 3 * x[/tex]

[tex]Triple\ of\ x= 3 x[/tex]

Next is to get the difference between 3x and 13

This is represented as [tex]3x - 13[/tex]

Lastly, Add x to the above:

[tex]x + 3x - 13[/tex]

[tex]4x - 13[/tex]

Hence, the variable expression is 4x - 13

Answer:

4.0

Step-by-step explanation:

Look at the decimal place next to the tenths place. It has a 2 in its place. The rule for rounding is that any number 4 or lower is rounded down. Any number 5 or above is rounded up. The number is 2, which is below 4, so we round down. The tenths place would stay the same because it can't get any smaller. Therefore, 4.028 is rounded down to 4.0

Answer:

[tex]4n-n^2[/tex]

Step-by-step explanation:

I use 'n' as the unknown value, but you can use any letter you want as the variable.

The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.

The square of the number would be n². Squaring a number is multiplying a number by itself.

The phrase 'difference between...' means subtraction.

Putting it together:

"The difference between the product of 4 and a number and the square of the number" would be:

[tex]4n-n^2[/tex]

Answer: [tex]x=-3[/tex]

Simplify both sides of the equation

[tex]1+-2x=-1+8+8x+-8x[/tex]

[tex]-2x+1=(8x+-8x)+(-1+8)[/tex] (Combine Like Terms)

[tex]-2x+1=7[/tex]

Subtract 1 from both sides

[tex]-2x+1-1=7-1\\-2x=6[/tex]

Divide both sides by -2

[tex]-2x/-2=6/-2\\x=-3[/tex]

Answer:

[tex]\Huge \boxed{x=-3}[/tex]

Step-by-step explanation:

[tex]1-2x= -1+8+8x-8x[/tex]

Combining like terms.

[tex]1-2x= 7[/tex]

Subtracting 1 from both sides.

[tex]-2x= 7-1[/tex]

[tex]-2x=6[/tex]

Dividing both sides by -2.

[tex]x=-3[/tex]

Answer:

Answer is 900.

Step-by-step explanation:

To find:

Increase #500 in the ratio 16:10

Solution:

New Number: Old Number = 16:10

We are given the old number as 500.

Let the new number after increase = [tex]x[/tex]

Now, using the above ratio:

[tex]x[/tex]: 500 = 16:10

[tex]\dfrac{x}{500} = \dfrac{16}{10}\\\Rightarrow x = 500 \times \dfrac{16}{10}\\\Rightarrow x = 50 \times 16\\\Rightarrow x = 900[/tex]

Therefore, the increased value of 500 in the ration 16:10 is 900.

Answer:

23 mpg

Step-by-step explanation:

We simply need to evaluate the given function at the speed requested (60 mph):

[tex]f(x)=32-0.15\,x\\f(60)=32-0.15\,(60)\\f(60)=23\,\,mpg[/tex]

First graph the center at (1,2). Then use your given radius to graph four points around the center. One vertical point above and one below the center, and one horizontal point to the right and one to the left of the center. Those points should be:

• (1,5)

• (1,-1)

• (-2,2)

• (4,2)

Then, to the best of your ability, draw a circle connecting those points.

I hope this makes sense. Please let me know if you have any further questions!

The equation of the circle that has a center at (1, 2) and a radius of 3 units will be (x - 1)² + (y - 2)² = 9. The circle is drawn below.

Let r be the radius of the circle and the location of the center of the circle be (h, k).

Then the equation of the circle is given as,

(x - h)² + (y - k)² = r²

The center of the circle is (1, 2) and the radius of the circle is 3 units. Then the equation of the circle is given as,

(x - 1)² + (y - 2)² = 3²

(x - 1)² + (y - 2)² = 9

The equation of the circle that has a center at (1, 2) and a radius of 3 units will be (x - 1)² + (y - 2)² = 9. The circle is drawn below.

Answer:

v = 0.834 m/s or 3 km/h

Step-by-step explanation:

Given that,

Distance between house and playground is 300 meters

If you went 300  metres away in 10 minutes and ran back and  reached in 2 minutes, it means total distance covered by you during whole journey is 300 m + 300 m = 600 m

Total time, t = 10 min + 2 min = 12 min = 720 seconds

Total distance covered divided by total time gives average speed. So,

[tex]v=\dfrac{600\ m}{720\ s}\\\\v=0.834\ m/s[/tex]

or

v = 3 km/h

So, the average speed is 0.834 m/s or 3 km/h.

Answer:

16x

Step-by-step explanation:

80 divided by 5 is 16, so the student can read 16 words per minute. X is the number of minutes.

The average reading rate per minute is 16 words/ min.

and its expression will be [tex]16x[/tex]  

where, [tex]x[/tex] represents the minutes

Answer:

This problem requires you to plug in the values to get an answer.

f(2)=1

f(-6)= 65

Step-by-step explanation:

You need to plug in each value in the equation.

[tex]f(2) = 2^{2} - 4(2) + 5[/tex]

[tex]f(2) = 4 - 8 + 5[/tex]

[tex]f(2) = - 4 + 5[/tex]

[tex]f(2) = 1[/tex]

For f(-6):

[tex]f( - 6) = ( - 6)^{2} - 4( - 6) + 5[/tex]

[tex]f( - 6) = 36 + 24 + 5[/tex]

[tex]f( - 6) = 65[/tex]

Answer:

1/2, 3/6 and 2/4 are equivalent fractions.

Step-by-step explanation:

To know if the fractions are equivalent, their simplest form should be the same.

So we must simplify all the fractions to their simplest form.

To find the simplest form of a fraction, we must divide the numerator and denominator with their GCF (Greatest Common Factor)

So:

1/2 = 1/2

1/3 = 1/3

3/4 = 3/4

3/6 = 1/2 ( The GCF for 3 and 6 is 3)

2/4 = 1/2 ( The GCF for 2 and 4 is 2)

4/10 = 2/5 ( The GCF for 4 and 10 is 2)

Because 1/2, 3/6 and 2/4 has the same simplest form, they are equivalent fractions.

Answer:

Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Answer:

It models exponential growth.

Step-by-step explanation:

7/4 > 1, so f(x) grows at an exponential rate as x increases.

A graph of f(x) is attached below, showing the exponential growth.

Their GCF is 1. They don’t have any others that are the same
