1/7 the speed of a cheetah is 10 mph because an average cheetah can run 70 miles per hour. This means time to do some division. Envision the denominator of 1/7 (7) as 70 and then the numerator (1) should be 10. Divide 70 by 7 should be 10. Hope this helps.
Part A: subtract 30 from both sides to get -vp<45. Then divide both sides by -v and flip the signs to get p>45/-v
Part B: subtract 3w from both sides to get -6r=30. Then divide -6 by both sides to get 3w/-6-5=r
I think it's just determining what the negative means. Negative with the x axis means to the left (because the left side is negative). Negative with the y axis is down (because the down side is negative.) So once you know that, it's obviously D because both are negative.
I hope that helped!

Answer:
Step-by-step explanation:
AT first, draw the reference line, which are given. If I take PQ as base, I won't need to draw PQ line as reference.
I took PQ(5.5cm) as base. Then, take 4.8cm in your compass by centering at point Q. Draw an arc. Then take 4.2 cm in your compass from the reference line which you have drawn and then centre at point P and draw an arc. Both the arcs will meet at one point. Then join the lines to form the Triangle PQR
