Hey there,
380 miles = 14 gallons
1 miles = 14 / 380
= 7 / 190
418 miles = 7 / 190 x 418
= 15.4 gallons.
Hope this helps :))

Remember
we can do anything to an equation as long as we do it to both sides
try to isolate the variable
you have 2 types
x+b=c
x/b=c
fior the first type, minus b from both sides to get
x=c-b
for the second, multiply both sides by b to get rid of the fraction to get
x=cb
also remember that -x times -1=x
b.add 25 to both sides
-a=20
multiply -1
a=-20
c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32
d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150
e. multiply both sides by 12
-l=144
multiply b y-1
l=-144
Answer:
exponents first then multiply and subtract after
Step-by-step explanation:
the answer is 5
Simplify the following:
3 x + 2 y + x + 3 y
Grouping like terms, 3 x + 2 y + x + 3 y = (2 y + 3 y) + (3 x + x):
(2 y + 3 y) + (3 x + x)
2 y + 3 y = 5 y:
5 y + (3 x + x)
3 x + x = 4 x:
Answer: 5 y + 4 x
