Answer:
18
Step-by-step explanation:
There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical music, 13.
4 + 3x = 13
3x = 9 . . . . . subtract 4
x = 3 . . . . . . divide by 3

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.
like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18
18 students like two types of music only.
Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Totally doable. Just break it into 2 shapes rectangles and triangles.
Rectangles: A=bh
so: 83×60
now since there are 3 rectangles with the same parameters multiply your answer by 3
put aside the rectangles.
Triangles:A= 1/2×b×h
so: A= 1/2 ×82× 76
Then multiply your answer by 2 since there are 2 triangles.
This will give you the answer 3116.
Now all that's left is to add the area from the rectangles and the area from the triangles.
Part 2 for your previous question. The third picture is called the Pythagorean theory. The equation is a squared + b squared =c squared. So take the meausurment of the "a" side and square it. Do the same with "b". Next add those two together then square root the answer.
Refer to the next picture. That was an example.
I think it’s 74 bc I got it right but your might be different
Circle area = PI * 13^2
circle area = 530.93
