Answer:

The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. The first term of the ratio is measured in cents; the second term in ounces. You can write this rate as 69¢/12 ounces or 69¢:12 ounces.

Twice a number, added to seven, is the same
eduard

Answer:

Your number is -10

Hope this helps :)

Step-by-step explanation:

Let x be the number

 

Twice a number is 2x

Added to 7 means + 7 so 2x + 7

Is means =

2x+7=

 

At this point I have to assume you mean

"is the same as three subtracted from THE SAME number"

Otherwise, rather than a number, we end up with the

equation of a line....

 

2x + 7 = x - 3   subtract x from both sides

x + 7 = -3        subtract 7 from both sides

x = -10

 

Your number is -10

 

Check:  2x+7 = x-3

           2(-10) + 7 = -10-3

           -20+7 = -13

            -13 = -13

            The answer fits the parameters of the problem.

Use the diagrams at the right to find the trigonometric ratio
zzz [600]
Hi, It is simple:

Sin(A) = a / c

Cos(A) = b / c

Tan(B) = b / a

Sin(J) = j / i

Cos(K) = j / i

Tan(K) = k / j


This are the answers
