Answer:
The answer is D.
Step-by-step explanation:
It is given that Gabriella swims 2 laps for 1 minute. So in order to find how many minutes did he swim for each lap, you have to divide it by 2 :
2 laps = 1 minute
2 laps ÷ 2 = 1 minute ÷ 2
1 lap = 1/2 minute
= 30 seconds
Test :
Gabriella swim 1/2 min per lap. So if he swim 2 laps, you have to multiply it by 2 :
1/2 × 2 = 1 minute
Answer: Three plus Five equals Eight or 3= a · 5= 5a
Step-by-step explanation:
Answer:
It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!
14r+20<14r+16 or 8−10r>15−9r
14r+20<14r+16
14r+20−14r<14r+16−14r(Subtract 14r from both sides)
20<16
20−20<16−20(Subtract 20 from both sides)
0<−4
8−10r>15−9r
−10r+8>−9r+15(Simplify both sides of the inequality)
−10r+8+9r>−9r+15+9r(Add 9r to both sides)
−r+8>15
−r+8−8>15−8(Subtract 8 from both sides)
−r>7
−r/−1 > 7/−1(Divide both sides by -1)
r<−7
Ur answer is:
r < - 7 OR 0 < - 4
