Answer:
1 is not a linear equation
2 is a linear equation
Answer:
$4
Step-by-step explanation:
16(1/4) = 4
For this, we need to find the lowest common multiple of 10 and 8
multiples of 10 : 10,20,30,40,50
multiples of 8 : 8,16,24,32,40
so the LCM of 10 and 8 is 40
therefore, they will both flash at the same time again in 40 seconds.
Answer:
Step-by-step explanation:
This question is about the benefits of estimation.
1300/13 is easy and results in 100.
1287/13 can be approximated by 1300/13: 1287/13 ≈ 100.
Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.
So: 1287/13 = 1300 - 13 = 1287. A nice bit of mental math!
They lose 4 yds on each of 3 plays......3 * -4 = -12
then they complete a 9 yd pass.....+ 9
-12 + 9 = -3 <== their change in yardage
