26

Answer: 26

Step-by-step explanation:

4(x-y)+2

Lets plug in 7 for x and 1 for y

4(7-1)+2=4(6)+2

4*6=24

24+2=26

26 is the answer

Answer:

x = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (9[tex]\sqrt{2}[/tex] )²

2x² = 162 ( divide both sides by 2 )

x² = 81 ( take the square root of both sides )

x = [tex]\sqrt{81}[/tex] = 9

The difference in the lowest amount of water and the highest amount of water students drank is 1/2

From the complete question (see attachment for line plot), we have:

Least = 1/8

Highest = 5/8

The difference is then calculated as:

Difference = Highest - Least

This gives

Difference = 5/8 - 1/8

Evaluate

Difference = 4/8

Simplify

Difference = 1/2

Hence, the difference in the lowest amount of water and the highest amount of water students drank is 1/2

Answer: You can save 15% or more on car insurance when you switch to Geico

Step-by-step explanation:

The difference in sale prices between the two stores is $4.5.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Given that, a $30 sweater is on sale for 20% off at Kohls.

Here, sales price = 30-20% of 30

= 30-20/100 ×30

= 30- 0.2×30

= 30-6

= $24

The same $30 sweater is on sale at Macy's for $5 off the price.

Here, sales price = 30-5% of 30

= 30-5/100 ×30

= 30- 0.05×30

= 30-1.5

= $28.5

So, difference in price = 28.5-24

= $4.5

Therefore, the difference in sale prices between the two stores is $4.5.

hi

if it's intersect, then :  

4x-10 = -4x+8

-10-8 = -4x-4x

 -18  = -8x

 -18/-8 = x

   18/8 = x

   9*2 /4*2 = X

   9/4 = X

So X is  9/4   then y  is  :   4( 9/4) -10 =  9-10 = -1  

Lines intercept at   (  9/4 ; -1)

Answer:

<B=119

Step-by-step explanation:

Each line of the triangle is straight, meaning they add up to 180. Additionally, all the angles of the triangle add up to 180. Using that, you can find the measure of each angle.

For <C;

180-112=68

So <C=68

For <A;

180-51-68=61

So <A=61

To make sure that all these angles add up correctly;

51+68+61=180

For <B;

180-61=119

So <B=119

Answer:

If all of the observed values in a sample are close to the sample mean, the standard deviation will be small (i.e., close to zero), and if the observed values vary widely around the sample mean, the standard deviation will be large. If all of the values in the sample are identical, the sample standard deviation will be zero.

Answer:

x=65

Step-by-step explanation:

That is the answer.

There were 18 one point shots and 37 two point shots.

Step-by-step explanation:

Let the number of one point shots be x and the number of two point shots be y .

So we have the system:

x + y = 55

x + 2y = 92

Subtract the first equation from the second, we get:

0 + y = 92 - 55 = 37.  

y = 37.

From equation 1 we have x = 55 - y

therefore x = 55 - 37 = 18.

Answer:

it is B 70° because if you add 40° + 70° = 110°

so then you need to subtract that from 180°.

180° - 110° = 70°

The measure of angle x is 150 degree.

The definition of "supplementary" in mathematics relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles.

As, the angle adjacent to 70° angle

= 180- 70

= 110°

Now, the angle supplement to x

x = 180 - (40+ 110)

x = 180 - 150

x = 30

So, the measure of angle x is 150 degree.
