HELP ME PLEAS!!A strool will need 678 masks for the students. If each package has 12 masks, how many packages will they need to buy
55 packages
56 packages
57 packages
58 packages

57 packages.

Step-by-step explanation:                                                                                               Just do 678 divided by 12 on a piece of paper or your calculator (or your head). The answer will be 57. You may ask, why? The answer is actually 56.5. Don't let B fool you. Since 56.5 is more than 56, B is wrong. However,  you can take the remaining masks and store them in the 57th package. So C is correct.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
