Answer 1

Answer:
You should set up an X and Y table. Make time X and Distance Y. (the table is like a cross: on the left top put x and left top put y. Then under the line list the x and y numbers given in order.) Then find the "slope" which is y/x (rise over run) then you get the increase rate of 45 mph. The relation between them would be D=45t

For the first football game of the season, 62732 fans attended. The number of fans at the second game was 469 morw than at the first game. What is the total number of fans that attended the first two games?

Answers

62,732+469=63,201

63,201+62,732=125,933

The first game had 62,732 fans, the second game had 63,201, how I got my answer.

You answerd the question to the first game which was 62,732, but the second game had 469 more than the first, so I added 62,732+469=63,201.

The football team has a total of 50 jerseys. There are 30 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys

Answers

$(medium\ sized)/(total\ number \ of\ jersey)*100\%=\n(30)/(50)*100\%=(3000)/(50)\%=60\%\n\nMedium \ sized\ jerseys\ are\ 60\%\ of\ all.$

Final answer:

60% of the jerseys are medium-sized. This is found by dividing the number of medium-sized jerseys (30) by the total number of jerseys (50), getting a result of 0.6, and then multiplying this by 100.

Explanation:

To find out what percent of the jerseys are medium-sized, you would need to divide the number of medium-sized jerseys by the total number of jerseys and then multiply by 100. Here's the calculation step-by-step:

Divide the number of medium-sized jerseys (30) by the total number of jerseys (50).
The result of this calculation is 0.6.
Multiply 0.6 by 100 to get the percentage.
This gives a result of 60.

So, 60% of the jerseys are medium-sized.

How to solve -2/3 w+5=4

Answers

$- (2)/(3) w + 5 = 4$

Refine:

$5 - (2w)/(3) = 4$

Multiply both sides by 3 :

$3 * 5 -3* (2w)/(3) = 3*4$

Refine:

$15 - 2 w = 12$

Subtract 15 from both sides:

$15 - 2w - 15 = 12 - 15$

$- 2w = -3$

Divide both side by -2 :

$(-2w)/(-2) = (-3)/(-2)$

$w = (3)/(2)$
