First, add 139+184=323.
Then multiply 170 to 3 to get the total number of points he must get to achieve that average.
170 multiplied to 3 gives you 510.
Then subtract 500- (139+184)= 187. This is the number of points Ben must get in his third game to have an average of 170

Answer:

187

Step-by-step explanation:

Were gonna start by writing an equation (139+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 187. Hope this helps.

Answer:

3)  x = 15; 95 and 85      4)  x = 12; 98 for both angles

Step-by-step explanation:

2x + 65 + 3x + 40 = 180       Set the equations equal to 180

5x + 105 = 180                      Combine like terms

     - 105  - 105                      Subtract 105 from both sides

5x = 75                                  Divide both sides by 5

x = 15

Plug 15 into both equations

2(15) + 65 = 95

3(15) + 40 = 85

4)  5x + 38 = 9x - 10             Set the equations equal to each other

  - 5x          - 5x                    Subtract 5x from both sides

 38 = 4x - 10

+ 10       + 10                         Add 10 to both sides

48 = 4x                                  Divide both sides by 4

12 = x

Plug 12 into both equations

5(12) + 38 = 98

9(12) - 10 = 98

Now, he wants to wrap it with wrapping paper. If the length of the shoebox measures 10 in, the width measures 5 in, and the heig
julia-pushkina [17]

The amount of wrapping paper he need to cover the shoebox is 190 square inches

<h3>Surface area of a box</h3>

The formula for calculating the surface area of a box is expressed as:

SA = 2(lw + wh + lh)

where

l is the length

w is the width

h is the height

Given the following parameters

l = 10in

w = 5in

h =3in

Substitute

S = 2(10*5 + 5*3 + 10*3)

S = 2(50+15+30)

S = 2(95)

S = 190 square inches

Hence the amount of wrapping paper he need to cover the shoebox is 190 square inches

Estimate √92 to the nearest integer.
Art [367]

Answer: 10

Step-by-step explanation:

This is because if it was 9, then 9^2 would be 81 and 10^2 would be 100. 81 is 11 numbers a way from 92, while 100 is 8 numbers from 92, making 10 the <u>closest</u> estimate.
