5 0

Hello there! Using the rules of addition, we can identify that when adding a positive to a negative number, the result shifts toward the positive side but takes the sign of the greater number. It will be demonstrated in this problem to simplify how problems like this are solved:

Step 1: Rewrite the problem

-14 + 7 = ?

Step 2: Since we’re adding 7 to a negative number, that means the negative number decreases by the quantity it’s being added by.

This means we would have to really subtract 7 from 14 to get 7.

Step 3: Keep the sign of the greater number

Since 14 is greater than 7, we will keep the negative sign in accordance.

Step 4: Simplify

-14 + 7 = -7

Using the rules of addition, we will find that -14 + 7 = -7. If you need additional help, let me know and I will gladly assist you.

Answer:

- 7

Step-by-step explanation:

note that

+ (- ) = - ( adding a negative is equivalent to subtraction )

- (- ) = + ( subtracting a negative is equivalent to addition )

then

7 + (- 14) = 7 - 14 = - 7

A sports team played 100 games last season. Did this team win at least half of the games it played last season? (1) The team won

Lelechka [254]

Answer:

Insufficient data.

Step-by-step explanation:

Given,

Total number of games = 100,

(1) The team won 60% of its first 65 games last season.

So, the number of winning games in 65 games = 60% of 65

$=\frac{60\times 65}{100}$

$=13\times 3 = 39$

But we do not know about the data for last 35 games,

Thus, the data is insufficient.

(2) The team won 60% of its last 65 games last season.

So, the number of winning games in last 65 games = 60% of 65 =39,

Thus, the total winning games = 45 + 45 = 90,

But we do not know about the data for first 35 games,

Thus, the data is insufficient.

When we combined both (1) and (2) statements,

we found that the maximum number of games won by the team = 39 + 39 = 78,

But there is a overlap of 30 games,

i.e. an unknown number will be subtract from 78 to find the exact number of winning games.

Hence, even after combining statements (1) and (2),

The data is insufficient.

Scientists found that the body of a male consists of 3.58×10^-4 lbs of zinc. What is the number written in standard notation?

notka56 [123]

Answer:

The number is 0.000358 lbs.

Step-by-step explanation:

Scientists found that the body of a male consists of $3.58 \times 10^{-4}$ lbs of zinc.

This is a scientific way of writing a number.

For, example 0.0023, a number in normal or standard notation can be scientifically written as $2.3 \times 10^{- 3}$ .

So, in our case, the number is $3.58 \times 10^{-4}$ lbs and we have to write this number in standard notation.

Then the number is 0.000358 lbs. (Answer)
