Answer: If you're not vegetarian, then you do not eat beef.

Step-by-step explanation:

Dismiss the 'if' and 'then':

- you do not eat beef

- you're not vegetarian

Now, all you have to do is switch their places:

- you're not vegetarian

- you do not eat beef

Now add the 'if' and 'then' back:

If you're not vegetarian, then you do not eat beef.

To answer this question you would need to solve this inequality. The first step would be to combine all three terms on the left-hand side of the greater than symbol. By doing this you would have 50w > 250. To solve this inequality divide both sides by 50. The answer is w > 5. In words, this means the number of walnuts per spoonful is greater than five.

On Saturday, Tom is paid $12.75 an hour plus a Saturday bonus of $25. Sara is paid $11.75 an hour plus a bonus of $29. For how l

iVinArrow [24]

Answer:

They must work for more than 4 hours for Tom's bonus to be greater than Sara's

Step-by-step explanation:

Tom pay: 12.75x+25

Sara pay: 11.75x+29

Tom>Sara = 12.75x+25>11.75x+29

subtract 25 both sides

12.75x>11.75x+4

subtract 11.75x both sides

x>4

Answer:

The length of the shortest piece is $1\textrm{ ft}$ .

The length of the medium-sized piece is $3\textrm{ ft}$ .

The length of the longest piece is $7\textrm{ ft}$ .

Step-by-step explanation:

The five-step method is GUESS method.

Given:

Length of copper wire, $L=11\textrm{ ft}$

Length of longest piece is 6 feet longer than the shortest one.

Length of the medium-sized piece is 3 times the shortest one.

Unknown:

Length of longest, medium-sized and shortest pieces of wire.

Let the length of shortest piece be $x$ feet.

Therefore, the length of longest piece is equal to $6+x$ .

And, length of the medium-sized piece is equal to $3x$ .

Evaluate:

Sum of lengths of longest, medium-sized and shortest pieces of wire is equal to the total length of wire. So,

$6+x+x+3x=11\\5x+6=11\\5x=11-6\\5x=5\\x=\frac{5}{5}=1$

Substitute and Solve:

Now, we have, $x=1$ .

Substitute 1 for $x$ and solve for each sizes of wire pieces. This gives,

Length of shortest piece = $x=1\textrm{ ft}$

Length of medium-sized piece = $3x=3(1)=3\textrm{ ft}$

Length of longest piece = $6+x=6+1=7\textrm{ ft}$

Therefore, the lengths of shortest, medium-sized, and longest pieces are $1\textrm{ ft}$ , $3\textrm{ ft}$ and $7\textrm{ ft}$ respectively.
