    In order to solve this equation that has variables on both sides, you should try to move either one constant term to the other side or one term with a variable to the other side first. Let's add -11x to both sides of the equation (we are carrying out the addition property of equality). Now, you should move a term from the side with more terms to the other side. Let's add 12 to both sides of the equation, so -12+12 will cancel out and equal 0, while 6+12 will equal 18. Finally, divide both sides of the equation by the coefficient of the variable, which is 18. This allows us to isolate the variable. Now, you should have your answer, which is 18/18 (you simplify this :) ) .

Mazyrski [523]
Let's look at work rates per minute.

Together they can paint the wall in x minutes.
Working together, in 1 minute, they do 1/x of the job.

The student who paints the wall in 16 minutes does 1/16 of the job in 1 minute.
The student who paints the wall in 24 minutes does 1/24 of the job in 1 minute.
Together, they do 1/16 + 1/24 of the job in 1 minute, but from above, we see that together, they do 1/x of the job in 1 minute, so 1/16 + 1/24 must equal 1/x. That gives us our equation.

1/16 + 1/24 = 1/x

1/16 * 3/3 + 1/24 * 2/2 = 1/x

3/48 + 2/48 = 1/x

5/48 = 1/x

x = 48/5 = 9.6

Answer: It takes them 9.6 minutes, or about 10 minutes to do the job together.

Anuta_ua [19.1K]

Answer:126 pounds

Step-by-step explanation:

The ratio from dolphins to pound of fish in one day is 1:7

So you have to multiply the ratio on both sides by 18

So you will get 18:126

Which method do you prefer to use to find sums- count by tens and ones, use compatible numbers, or use friendly numbers and adju
Usimov [2.4K]

I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:


Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:


64 ÷ 4 = 16


So, we have used mental arithmetic to solve a more complex problem.
