6x the number.

Step-by-step explanation:

"Twice a certain number" means that you are multiplying that number (x) by 2.

The resulting number would be 6x greater than the original number.

$55 per gallon. 1 gallon covers 100sqft. What is the price per sqft?
marta [7]

the price is 0.55$ per square foot

Step-by-step explanation:

We can solve the problem by using the rule of three.

In fact, we know that:

1 gallon covers an area of 100 ft^2

While the price per gallon is

$55 per gallon

This means that the price per 100 ft^2 is $55, since 1 gallon cover 100 ft^2

Therefore, to find the price per square foot, we can write

\frac{55}{100}=\frac{x}{1}

WHere x is the price per square foot. Solving for x,

x=\frac{55}{100}=0.55\$

So, the price is 0.55$ per square foot.

PLEASE I REALLY NEED HELP!
vagabundo [1.1K]

Answer:

\frac{3}{28}

Step-by-step explanation:

Probability (P) is calculated as

P = \frac{requiredoutcome}{count}

The first required outcome is a red sweet from a total of 3 + 5 = 8

P( red) = \frac{3}{8}

There are now 2 red left and a count of 7, since 1 has been eaten, thus

P( second red ) = \frac{2}{7}

P( red and red ) = \frac{3}{8}  × \frac{2}{7} = \frac{6}{56} = \frac{3}{28}
