In an​ orchestra, 22 people can play stringed​ instruments, 17 can play​ brass,15 and can play percussion.​ Further, 8 of the performers can play both strings and​ brass, whereas 7 can play both strings and percussion. If no one can play all three types of​ instruments, what are the maximum and minimum numbers of people in the​ orchestra? ​(Hint​: Consider expressing the numbers in some of the regions of your diagram in terms of a single​ unknown, say​ x.)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

answer: about 22.67
