Answer:
There are 47.12 liters in 12.4 gallons of gasoline.
Option C is correct option.
Step-by-step explanation:
Total Gasoline bought = 12.4 gallons
We are given:
1 gallons = 3.8 liters
So.=, we need to find how many liters in 12.4 gallons of gasoline
1 gallon = 3.8 liters
12.4 gallon = 3.8*12.4
= 47.12 liters
So, there are 47.12 liters in 12.4 gallons of gasoline.
Option C is correct option.

9. Sobre o estudo de equações, escreva V para as afirmações verdadeiras e F para as falsas.
a) ( ) A expressão 17 - 4x + 25 representa uma equação.
b) ( ) O número 23 representa um dos membros da equação -9x + 4 = 23.
c) ( ) Na equação x + 4 = 3x + 20, a incógnita é x.
d) ( ) A equação 3y - 15 = 0 não tem segundo membro.
Answer:
$5x + $4y ≤ $120
let x = 10
y = 5
$70 ≤ 120
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater or equal to
≤ means less than or equal to
the total amount Shanley has is $120. She can spend less than this amount or the amount exactly. So, the inequality sign to be used is ≤
$5x + $4y ≤ $120
let x = 10
y = 5
(50) + 20 ≤ 120
$70 ≤ 120
