36 x 62 = 2232
Answer:
x = 3
Step-by-step explanation:
95 + 85 + 100 + 27x -1 = 360
280 + 27x - 1 = 360
279 + 27x = 360
27x = 81
x = 3
Double check your work:
95 + 85 + 100 + 27(3) - 1 = 360
95 + 85 + 100 + 81 -1 =360
360 = 360
Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
Answer: The graph is a solid line. The test point (0,0) does not satisfy the inequality.
Explanation:
The line is solid because it is less than or EQUAL TO. The test point does not satisfy because if you replace y and x with 0, it will not be true. 0 is not less than or equal to -3, therefore (0,0) does not satisfy the inequality.
Answer: ∡RSQ and ∡TSQ
Supplementary angles are angles that add up to 180 degrees. We can see in the picture that both angles are located on the same line, and no other angles are involved, so they must equal 180.
We can also use the process of elimination:
- ∡RSQ and ∡UVS are congruent because they are consecutive angles.
- ∡RSQ and ∡WVX are also congruent because they are alternate exterior angles.
- ∡RSQ and ∡TSV are also congruent because they are vertical angles.
