Answer:
850 but im not sure lol
Step-by-step explanation:
645 + 225 = 870
1,320 - 870 = 450
450 + 350 = 800
800 + 50 = 850
He can round 0.85 up, because its over .50.
He can round 15.92 up, because it is also over .50.
16 + 1 = 17 is the estimate.
Answer:
59.25 < hb ≤ 86.25 (also = 59.3 < 1dp ≤ 86.2 to 1dp)
Step-by-step explanation:
60- 0.75 = human height therefore 59.25 < h ≤ ? then to find greatest height we subtract again 87 - 0.75 = 86.25 and fill in 59.25 < h ≤ ? = 59.25 < h ≤ 86.25 and should we show inhes to 1 dp we keep lowest rounded up 59.3 < 1dp ≤ 86.2 as lowest bound is 59.15 < lb ≤ 86.15 = 59.25 < hb ≤ 86.25
Just plug in and solve
5x − 3y − z → <span>5(-2) − 3(2) − (-3)
</span>5(-2) − 3(2) − (-3) → -10 - 6 +3
-10 - 6 +3 → -16 + 3
-16 + 3 = -13
answer is -13
