Four consecutive even integers are such that the sum of the second and fourth is 76. What is the sum of the first and third integers?

Answer:

Below

Step-by-step explanation:

● x-20 = y+20 (1)

● 2(y-22) = x+22 (2)

This is a system of simulataneous equations

Let's simplify the expressions first

● x -20 = y + 20 (1)

Add 20 to both sides

● x -20 + 20 = y+20 +20

● x = y + 40 (1)

● 2(y-22) = x+22 (2)

● 2y - 44 = x +22

Substrat 22 from both sides

● 2y-44-22 = x+22-22

● 2y -66 = x (2)

This is the new system:

● x = y+40 (1)

● x = 2y-66 (2)

Substract (2) from (1)

● x-x = y+40-(2y-66)

● y+40-2y+66 = 0

● -y +106 = 0

● y = 106

Replace y with 106 in (1)

● x = y +40

● x = 106+40

● x = 146

So the solutions are (146,106)

Answer: The measure of angle 1 is 39 degrees,the measure of angle 2 is 78 degrees and the measure of angle 3 is 63 degrees.

Step-by-step explanation:

We will represent the measure of angle 1 by x because it is unknown.

It says that the measure of angle 2 is twice angle 1   so we could represent that as  2x  and the measure of angle 2  is 15 less than angle 3 and we could also represent that by  2x - 15.

Now we know they all add up to 180 so add them up and set them equal to 180 and solve for x.

x + 2x + 2x -15 = 180  

5x - 15 = 180

      +15   +15

5x = 195

x = 39  

If x is equal to 39 then the measure of angle 1 is 39 degrees and the measure of angle 2 is twice that so 2(39) = 78   which also gives us the measure of angle 2 as 78.

For angle 3 it says that it has to be 15 less than the measure of angle so  subtract 15 from  78 to find the measure of angle 3.

78 - 15 = 63   The measure angle 3 is 63 degrees. Now add the measures all together to see if they equal 180 degrees .

Check:

39 + 78 + 63 = 180

  180 = 180

Answer:

D

Step-by-step explanation:

The area of a rectangle is given by the formula:

[tex]A=\ell w[/tex]

So, we are given that the area is:

[tex]x^3-5x^2+3x-15[/tex]

And the width is:

[tex]x^2+3[/tex]

And we want to find the length. To do so, first substitute the expressions into the equation:

[tex]x^3-5x^2+3x-15=(x^2+3)\ell[/tex]

Thus, to find the length, divide by (x²+3):

[tex]\displaystyle \ell = \frac{x^3-5x^2+3x-15}{x^2+3}[/tex]

We can factor the numerator:

[tex]x^3-5x^2+3x-15[/tex]

From the first two terms, factor out a x².

From the third and fourth terms, factor out a 3:

[tex]=x^2(x-5)+3(x-5)[/tex]

Combine:

[tex]=(x^2+3)(x-5)[/tex]

Putting this back:

[tex]\displaystyle \ell = \frac{(x^2+3)(x-5)}{x^2+3}[/tex]

Cancel:

[tex]\ell =x-5[/tex]

Hence, our answer is D.

5 represent calories from other ingredients

c= 5 1/2 grams

Step-by-step explanation:

Total calories=c grams of carbohydrates + other ingredients

Total calories in granola bite=27

The equation 4c + 5 = 27 represents the relationship between these quantities

1. 5 represent calories from other ingredients

2. Priya said that neither 8 nor 3 could be the solution to the equation

4c + 5 = 27

When the solution is 8

4(8)+5=27

32+5=27

37 =27

Solution 8 gives a higher calories than total calories

When solution is 3

4(3)+5=27

12+5=27

17=27

Solution 3 gives a lower calories than total calories

3. Solution to the equation

4c + 5 = 27

Subtract 5 from both sides

4c+5-5=27-5

4c=22

Divide both sides by 4

c=22/4

=5 2/4

=5 1/2

c= 5 1/2 grams

Step-by-step explanation:

To find the number of hours it takes to cook 3 kilograms of meat, we must fist find the rate of the ration we have:

12 : 5

= 12 / 5

= 2.4

This means that if you mulitply this by the value of the weight of meat, you'll get the amount of time it takes to cook that amount of meat.  We can do ths is find the time it takes to find the hours it takes to make 3 ilograms of meat:

x : 3

x = 3 * 2.4 = 7.2

x : 3

= 7.2 : 3

I takes 7.2 hours to cook 3 kilograms of meat.  You can use this process to find all the other hours based on the weight.

Step-by-step explanation:

First I figured out the area of the square which is 18×18=324

Then I found out the are of the circle which is 254.47, so 324 - 254.47 = 69.53

Then there are 4 times the shaded are so divided by 4, so 69.53  ÷ 4 = 17.3825

PLEASE GIVE BRAINLIEST!

Answer:

shaded area = 17.38 cm²

Step-by-step explanation:

given:

diameter of circle = 18 cm and = side of square

π = 3.142

shaded area = ( Area of square - Area of circle ) x 1 / 4

Area of square = s² = 18² = 324 ²cm

Area of circle = π d² / 4

                       = 3.142 (18²) / 4

                       = 254.5 cm²

therefore, shaded area = ( 324 cm² - 254.5 cm² ) * 1/4

                                       = 17.38 cm²

Answer: To simplify this problem you combine the like terms in the equation (numbers with the same variables.)

Demo: 12r + -4r = 8r

Answer:

8r + 14s - 7T

Step-by-step explanation:

Hello!

We have to make sure the terms are like terms before we add them.

Like terms are terms with the same variable so we can add r's with r's, t's with t's, etc.

There are two r's and two s's so we can simplify those

12r - 4r = 8r

5s + 9s = 14s

Now put these all together with the T in the original equation to get the answer

8r + 14s - 7T

The equation formed using the given data is 195 = x + 12 and your final score is 183 points.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say your final score is x

Given that,

Your final score x is 12 points less than your friend's final score.

So,

x = friend final score - 12

Now,

Friend final score = 195

So,

x = 195 - 12

x + 12 = 195

195 = x + 12

Now,

x = 195 - 12 = 183

Hence "The equation formed using the given data is 195 = x + 12 and your final score is 183 points".

Answer:

D

Step-by-step explanation:

So we have the equation:

[tex]ax+by+c=0[/tex]

First, let's convert this to slope-intercept form.

Subtract ax from both sides:

[tex]by+c=-ax[/tex]

Subtract c from both sides:

[tex]by=-ax-c[/tex]

Divide everything by b:

[tex]y=-\frac{a}{b}x-\frac{c}{b}[/tex]

We are told that a>0, b<0, and c>0.

In other words, a is positive, b is negative, and c is positive.

The slope of the equation is -a/b.

Since a is positive and b is negative, we will have:

-(+)/(-).

The negatives will cancel out. Therefore, our slope will be positive.

Since our slope is positive, our line must be upwards sloping. Eliminate answers A and C.

Also, our y-intercept is:

-c/b.

c is positive and b is negative. Thus, similarly:

-(+)/(-).

Again, the negatives cancel. This means that the y-intercept must be positive.

Out of B and D, the graph that has a positive y-intercept is D.

D is our answer :)

The perimeter of the triangle is calculated by adding the values of the three sides.

In this case, the values of the individual sides are expressed algebraically.

We can still add them, however, taking into consideration like terms.

Perimenter of triangle = (4.1p+4.4q) + (6.4p-5.1r) + (1.3r+6.3q)

Perimeter = 4.1p + 6.4p + 4.4q + 6.3q -5.1r + 1.3r

Now we have grouped them, we can add the different groups separately

Perimeter = 10.5p + 10.7q - 3.8r

Answer:

$122.28

Step-by-step explanation:

Give the following :

Insurance worth = $240,000

Price sold = $225

P(survival) = 0.999572

P(death) = 1 - 0.999572 = 0.000428

If she survives, insurance firm makes $225

If she dies, insurance firm pays $240,000, hence the company losses :

$(225 - 240,000) = $−239775

Expected value (E(x)) = sum of P(i) * X(i)

E(x) = (P(survival) * profit made) + (P(death) * loss incurred)

E(x) = (225 * 0.999572) + (0.000428 * −239775)

= 224.9037 - 102.6237

=$ 122.28

Answer:

$773.3587

Step-by-step explanation:

The probability that the female survives = 0.999572

therefore, probability that female dies = 1-0.999572 = 0.000428

if the female survives the insurance company makes = $225

x=$250

If the female dies the insurance company pays $240,000.

So, the amount with the company = 240000-225 = $ 2390775

Therefore Expected value = 250(0.999572)-2390775(0.000428)= $773.3587

im not sure how the data should be interpreted but here is the distribution. It goes up by .416

Step-by-step explanation:

the average of the first 8 games is 24

the average of the 12 games is 24.416

The mean of the data of the given basketball player will increase if she scored 24, 22, 27, and 28 points in her next four games.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Given that the number of points scored by a basketball player in the first eight games is 15, 35, 18, 30, 25, 21, 32, and 16. Therefore, the mean of the first 8 games is,

Mean = (15 + 35 + 18 +30 + 25 + 21 + 32 + 16)/8

          = 176/8

          = 22

Now, the player scored 24, 22, 27, and 28 points in her next four games. Therefore, the mean will be,

New Mean = (15 + 35 + 18 +30 + 25 + 21 + 32 + 16 + 24 + 22 + 27 + 28)/12

                  = 277 / 12

                  = 23.0833

Hence, the mean of the data of the given basketball player will increase if she scored 24, 22, 27, and 28 points in her next four games.
