If your chemistry grade is broken down so that 70% of it is exams, 20% is a lab, and 10% is homework, and your average scores out of 100 points in each area are:

exams 85
labs 75
homework 96
calculate your weighted average.

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice

Need this asap if anyone can i would be very grateful. if you could show workings that would really

Iwill give you ! what is the measure of ∠v ?
