Answer:

The student's average is 86.6.

Step-by-step explanation:

Since a student is trying to calculate his semester average, and he knows that his test average is an 85, his quiz average is a 79, homework is a 92, and classwork is a 95, if tests and quizzes are worth 30% each , and homework and classwork are worth 20% of his overall average, to determine what is his average the following calculation must be performed:

(85 x 3 + 79 x 3 + 92 x 2 + 95 x 2) / 10 = X

(255 + 237 + 184 + 190) / 10 = X

866/10 = X

86.6 = X

Therefore, the student's average is 86.6.

What value of b will make the expressions −12.8x+b and −3.2(4x−2.1)+2.4 equivalent?
telo118 [61]

- 12.8x + b =  - 3.2(4x - 2.1) + 2.4

Distribute -3.2 through the parentheses

- 12.8x + b =  - 12.8x + 6.72 + 2.4

Cancel equal terms on both sides of the equation

b = 6.72 + 2.4

Add the decimals

b = 9.12

<em>Thus, The expression are equivalent at b = 9.12...~</em>
