Answer:
6, 1, 8, -16
Step-by-step explanation:
For each input we divide it by 2 and then add 3 to get the output:
6/2+3=3+3=6
-4/2+3=-2+3=1
For each output we subtract 3 and multiply it by two to get the input:
(7-3)*2=4*2=8
(-5-3)*2=-8*2=-16
Answer:
Easy, all you have to do is add em all together 80+70=150 and 2+6=8 so 150+8=158
Step-by-step explanation:
He can split his pop into in whole mLs any n glasses such that n is a divisor of 30, namely any n in {1,2,3,5,6,10,15,30}. The fraction in each glass is then 1/n.
Answer:
The answer to your question is the first rain lasted 40 hours and the second rain lasted 30 hours.
Step-by-step explanation:
Data
1st 15 ml/h = x
2nd 30 ml/h = y
Total time = 70 h and 1500 ml
1.- Write 2 equations
First rain + second rain = 70 h
x + y = 70 (I)
15x + 30 y = 1500 (II)
2.- Solve equations by elimination
Multiply first equation by -15
-15x - 15y = - 1050
15x + 30y = 1500
0x + 15y = 450
y = 450 / 15
y = 30 h
x + 30 = 70
x = 70 - 30
x = 40 h
3.- Conclude
The first rain lasted 40 h and the second rain lasted 30 h.
Step-by-step explanation:
f(x) = 4x - 7
f(2) = 4(2) - 7
f(2) = 8 - 7 => 1
