Adrian's mean score for four tests is 64%. He wants to increase his mean to 68% after the fifth test. What does he need to score in the fifth test?

He has to score 84 %

Step-by-step explanation:

64 + 64 + 64 + 64  = 256

5*68 = 340

340 - 256 = 84

(64 + 64 + 64 + 64 + 84)/ 5 = 68

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
