2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)

To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.

In your class, you have scores of 66, 74, 71, and 81 on the first four of five tests. To get a grade of Upper C, the averag

Ludmilka [50]

Answer:

A score of greater than equal to 128 and less than 188 will get a grade of Upper C

Step-by-step explanation:

We are given the following in the question:

Scores:

66, 74, 71, 81

Let x be the score on fifth test.

$\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

To get a grade of Upper C, the average of the first five tests scores must be greater than or equal to 70 and less than 80.

$70 \leq \text{Average} < 80$

The fifth test counts as two tests.

Putting the values we get:

$70 \leq \dfrac{66 +74+71 + 81+ x}{6} < 80\\\\420 \leq 292 + x < 480\\420 -292 \leq x < 480 - 292\\128 \leq x < 188$

Thus, a score of greater than equal to 128 and less than 188 will get a grade of Upper C

artcher [175]

Lets first take out the GCF of the numbers, we get

3 ( 4a^2 - 12ab + 9b^2)

= 3 ( 2a - 3b)(2a - 3b)
