Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
If 40% of the cameras are digital, that means 60% of them are not digital.
If 60% of all cameras is 24, then 20% is 8, making 40% 16 cameras.
Answer:
x=1 2/3y-1/3z hope this helps!
Step-by-step explanation:
5y=3x+z
-z -z
5y-z=3x
/3 /3
1 2/3 - 1/3z=x
x=1 2/3y-1/3z
6 gallons are lost every 30 second so .2 gallons are lost every second
