We need more details to answer. You did forget to mark ST as 16 but I see no problem with the NQ. NQ should be self-similar to SU.

Thats about 9:12. She should have enough information for them to be self-similar because you can find angle S by adding angle T and U together and subtracting 180 by the sum of those numbers.

I am not sure what the question is asking though specifically so can you provide more info

Using the weighed mean formula, it is found that Mara's average for the course was of 68.6.

<h3>What is the weighed mean?</h3>

The weighed mean is given by the <u>sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights</u>.

In this problem, the weights are as follows:

A quiz has a weight of 1.

A test has a weight of 2.

The final examination has a weight of 4.

Hence, her weighed mean is given as follows:

$M = \frac{2(65 + 62 + 60) + (61 + 96 + 80 + 89) + 4(65)}{6 + 4 + 4} = 68.6$

Mara's average for the course was of 68.6.

The first equation has a slope of 1 and a y-intercept of 2.

The second equation has a slope of -1 and a y-intercept of 3.

The two lines cross at the point (0.5, 2.5), which is the solution to the system of equations.
