Answer:

To subtract a number from another number, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number

Step-by-step explanation:

(i) Evaluate (+6) – (+2)

= (+6) + (-2) (charging the sign of the number to be subtracted and then adding)

On subtracting smaller number 2 from bigger number 6; we get 6 – 2 = 4

Since, the sign of bigger number is + (positive)

= +4 or 4

Therefore, (+6) – (+2) = 4

(ii) Evaluate (+5) – (-3)

= (+5) + (+3) (charging the sign of the number to be subtracted and then adding)

We know, to add a positive (+ ve) number to a positive (+ ve) number, the numbers should be added and positive sign should be attached to the sum obtained.

= +8

Therefore, (+5) – (-3) = 8

Help Me Please I need help
Neko [114]

Answer:

Step-by-step explanation:

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} )

y = mx + b

~~~~~~~~~~~

(4, 5)

( - 6, 15)

m = (15 - 5) / ( - 6 - 4 ) = - 1

y - 5 = ( - 1)( x - 4 )

y =<em> (- 1) </em>x + <em>9</em>

Which steps should be taken to solve the equation
Leviafan [203]

Answer:

Remove 1 x-tile from both sides.

Remove 3 unit tiles from both sides.

Step-by-step explanation:

2x + 3 = x + 5

First we want all the variables on one side

Subtract x from each side so Remove 1 x-tile from both sides.

x+3 = 5

Now we need to get all the constants on the same side

Subtract 3 from each side so Remove 3 unit tiles from both sides.

x = 5-3

x=2

on the football team, two out of every seven players are seniors. if the team has 84 players, how many are not seniors.
zaharov [31]

There are 60 players on football team that are not seniors.

Step-by-step explanation:

<u>Method 1:</u>

Given

Total students = 84

Also given that

2 out of 7 are seniors

Which is 2/7

So in order to find the total number of seniors we will multiply the whole number of students to 2/7

Senior\ students = \frac{2}{7} * 84\\= 24

So there are 24 seniors on the football team.

Players that are not seniors = 84 - 24 = 60

There are 60 players who are not seniors.

<u>Method 2:</u>

We can divide the total number by 7, to get how many sets of 7 players will be there

= 84/7 = 12

Now,

Multiplying 12 with 2 will give us the number of seniors in football team.

12*2 = 24 seniors

So,

Not seniors =84-24 = 60
