3C+2F=22
3C +2F-2F = 22-2F
3C = 22 - 2F
3C÷3 = 22÷3- 2F÷3
C= 22/3-2F/3
3C+2F=22
3C-3C +2F = 22 -3C
2F = 22 - 3C
2F÷2 = 22÷2 - 3C÷2
F= 11-3C/2

It is impossible to solve for 2 unknown variables in an equation. In order to solve this, you must think mentally.

What two numbers can you add to make 22?
A good example is 15 and 8.

Can 15 and 8 be divided into smaller numbers?
Yes.

15/3 = 5
8/2 = 4
   ^
   Notice how I'm dividing by the coefficient? *3*c and *2*f

So C can be 5 and F can be 4.

3(5) + 2(4) = 22
15 + 8 = 22
22 = 22

Brut [27]

Answer:

Step-by-step explanation:

The total angle of a circle is 360

If you divide that angle into six parts, you are basically multiplying by 1/6.

You multiply the total angle measure of the circle by 1/6 (or divide it by 6) to get the answer which is the 2nd blank.

1/6 * __360_ = __60__

Shureka Washburn has scores of 67​, 68​, 76​, and 63 on her algebra tests. a. Use an inequality to find the scores she must make
mash [69]
Average=(total number)/(number of items)
given that the final exam counts as two test, let the final exam be x. The weight of the final exams on the average is 2, thus the final exam can be written as 2x because any score Shureka gets will be doubled before the averaging.
Hence our inequality will be as follows:
(67+68+76+63+2x)/6≥71
(274+2x)/6≥71
solving the above we get:
274+2x≥71×6
274+2x≥426
2x≥426-274
2x≥152
x≥76

b] The above answer is x≥76, the mean of this is that if Shureka is aiming at getting an average of 71 or above, then she should be able to get a minimum score of 76 or above. Anything less than 76 will drop her average lower than 71.

Answer:

the capacity of the airplane be 200 passengers

Step-by-step explanation:

According to the question, the data provided is as follows

Number of passengers in an airplane = 180

Capacity = \frac{9}{10}

Based on the above information

Let us assume the capacity of the airplane be x

So the equation would be

\frac{9}{10} \times x = 180\\\\\\x = \frac{1,800}{9}

So x = 200

Therefore the capacity of the airplane be 200 passengers

We simply applied the above equation so that the capacity of the airplane could come
