Let x be the money Antonio has.
Let y be the money Dominic has.
x-18=y (here, I just put in the equation)
Since we are not given any information about the money that Dominic has or Antonio has, we would have to create an equation that would fit all the situations.
Hope I helped :) <span />

why does so many people want to play fortnite anyone got cold war or modern warfare?
Step-by-step explanation:
If it's just the 7 that's repeating, let
<em>x</em> = 0.1777...
Then
10<em>x</em> = 1.777...
100<em>x</em> = 17.777...
100<em>x</em> - 10<em>x</em> = 17.777... - 1.777...
90<em>x</em> = 16
<em>x</em> = 16/90 = 8/45
If both 1 and 7 are repeating, let
<em>x</em> = 0.171717...
Then
100<em>x</em> = 17.171717...
100<em>x</em> - <em>x</em> = 17.171717... - 0.171717...
99<em>x</em> = 17
<em>x</em> = 17/99

Answer:
Step-by-step explanation:
Let x be the random variable representing the algebra test scores of the students. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 81.5
σ = 5.1
the probability that a student scores below 76.4 is expressed as
P(x ≤ 76.4)
For x = 76.4
z = (76.4 - 81.5)/5.1 = - 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
For x = 8
z = (8 - 6)/1 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.159
Therefore, the number of students that scored below 76.4 is
0.159 × 130 = 21 students
