Each person payed $175
First add the cost up:
$900 on transportation + $500 hotel room= $1400 total
8 people paying $1400 means divide 1400 by 8 to see how much one person payed.
1400/8 = 175
Each person payed $175
0.00305 and 8920000...if the exponents are negative 3 and 6
Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5.
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.
G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
20 times
This is just simple division. Do 8 divided by 0.4 and you should get 20
Hope this helps!
