The Least Common Multiple (LCM) will calculate when they are watered on the same day.
LCM of 4 and 7 is 28.
Answer: They will be watered together every 28 days.
Answer:
2 oldies and 6 new releases
Step-by-step explanation:
let x equal number of oldies
let y equal number of new releases
2x + 4y = 28
x + y = 8
x = 8 - y
2(8 - y) + 4y = 28
16 - 2y + 4y = 28
2y = 28 - 16
2y = 12
y = 12/2
y = 6
x = 8 - y
x = 8 - 6
x = 2
0.3% = 0.003..." of " means multiply
0.003(200) = 0.6 <==
0.85% = 0.0085
0.0085(600) = 5.1 <==
what u can do to turn the percents to decimals is divide by 100.
0.3 / 100 = 0.003 and 0.85 / 100 = 0.0085
or u can move the decimal two spaces to the left
The correct answer is 200 .
