Answer:

Between 19 and 55, inclusive

Step-by-step explanation:

70 < Average < 79 (inclusive)

4×70 < sum < 4×79 (inclusive)

280 < sum < 316

280 < 92 + 84 + 85 + X < 316

280 < 261 + X < 316

19 < x < 55

Fourth score can be between 19 and 55, inclusive

oee [108]

Answer:

x = 2.95

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

0.45 plus 9x equals 27

0.45 + 9x = 27

<u>Step 2:  Solve for x</u>

0.45 + 9x - 0.45 = 27 - 0.45

9x / 9 = 26.55 / 9

x = 2.95

Answer:  x = 2.95
