Answer:
34.06=20+0.19m
Step-by-step explanation:
The 20 dollars is a one-time thing so we don't need a variable for that. The 0.19 per mile does because the cost will depend on how many miles you drove (I used the variable 'm' but you could use a different letter). Altogether the bill costs 34.06 so that will go on the opposite side of our equal side.
34.06=20+0.19m
First we need to isolate 0.19m to find the number of miles the customer drove, and we can do that by subtracting 20 on each side.
34.06-20=20-20+0.19m
14.06=0.19m
Now we divide 0.19 because 0.19 is multiplied to m and division is the opposite operation
m=74
This means that the customer drove 74 miles.
3/4 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (4)(12)
3x = 48
x = 48/3
x = 16
now notice this.....12/16 reduces to 3/4....probability's are nothing but equivalent fractions

Answer: 2(x+3)</h3>
Explanation:
x = number of coins Liam has in his bag
Each bag Mia has is 3 greater than x.
So x+3 is the number of coins in one bag for Mia. Two such of her bags gives 2(x+3) = 2x+6 coins.
