Answer:
f(x) = 25.50x Roberto can buy 7 video games
Step-by-step explanation:
Each game is $25.50 which in math means it has an "x"
So if x=1 then 25.50x says that 1 video game is $25.50
Set up the equation:
200 = 25.50x (divide both sides by 25.50 to isolate the x)
200/25.50 = 7.84
x = 7.84
You can't have 0.84 of a video game, so Roberto can only buy 7 of them.
Answer:
0.25
Step-by-step explanation:
As a decimal, 0.25
As a fraction, 1/4
As a percentage, 25%
Given: 5x – 4 + 13x = 5
Combine like terms in the given expression.
⇒ (5x + 13x) – 4 = 5
⇒ 18x – 4 = 5
By addition property of equality, add 4 on both sides to equal to the expression.
⇒ 18x – 4 + 4 = 5 + 4
⇒ 18x = 9
By division property of equality, divide 18 on both sides to equal the expression.
⇒ 
By symmetric property of equality, both sides are equal
⇒ 
Hence,
.
