What is the value of the expression below when w=7 and x=5
3w + 10x

Answer:

The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).

Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.

Now plug everything in the formula.

2(3.14)(2) = 12.56.

The circumference of the trashball is 12.56 in.

The equation of line shown in figure is,

⇒ y = x - 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (4, 0) and (0, -4).

Now,

Since, The equation of line passes through the points (4, 0) and (0, -4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 4 - 0) / (0 - 4)

m = - 4 / -4

m = 1

Thus, The equation of line with slope 1 is,

⇒ y - 0 = 1 (x - 4)

⇒ y = x - 4

Therefore, The equation of line is,

⇒ y = x - 4

So if theres 45 students in total, thats 100% of students, nine of those would be 20%

Answer:The length of the trip is 780 mile

Answer:

To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:

Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.

Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.

Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.

Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.

Use mental math to add the terms, which gives you a result of 15.8.

Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.

Answer: (1, 2)

which means

x = 1

y = 2

Step-by-step explanation:

y = -x + 3

y = 2x

Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.

Substitute.

-x + 3 = 2x

Add x to both sides.

3 = 3x

Divide by 3.

3/3 = x

1 = x

We can put the 1 in for x in either equation.

y = 2x

y = 2(1)

y = 2

Putting x for 1 into the other equation is a good check.

y = -x + 3

y = -1 + 3

y = 2

So the x and y that work in both of these equations is:

x = 1 and y = 2

The form that was asked for was ( , ).

So the answer is

(1, 2).

Answer:The mean goes up from approximately 80.4 to 82.

Step-by-step explanation:

Before adding 101°, the mean i2:

(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57)/12 = 80.4

After adding the value 101°, the mean is:

(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 101)/13 = 82

Step-by-step explanation

1inch snow in am plus 1in snow in pm equals a total of 2in snow for that day.

The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

4x - 5 (2x + 1) = 6x + 1

4x - 10x - 5 = 6x + 1

-6x - 5 = 6x + 1

-5 - 1 = 6x + 6x

-6 = 12x

x = -6/12

x = -1/2

This means,

The equation has one solution.

Thus,

The equation has one solution.

Answer: The correct answer would be

D. an = 4.2n-1

Step-by-step explanation: First, calculate the ratios between each term and the one that precedes it.

8/4=2 ....16/8=2...32/16= 2...

Upon comparing the ratios we see the ratio between each term and the one that precedes it is 2 for all the terms, the sequence is geometric, and the common ratio is r = 2.

Now, we simply need to find the other unknown values in the equation, a1= the first term of the sequence which is 4, Therefore a1=4

Looking at the options provided we see that no further missing quantity can further be found so we put this in the equation provided for a geometric sequence.

We get 4. 2n-1, which is our answer.
