Let’s go!
You combine like terms then complete the multi step equation.
So you would get 5+2n=29
So that equals 17 :)
Given:
Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.
He is only allowed to work 13 hours total per week.
He wants to make at least 65 dollars.
To find:
The system of inequalities to represent this situation.
Solution:
Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.
He is only allowed to work 13 hours total per week. It means sum of x and y must be less than or equal to 13.

He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.

Number of hours can not be negative.
.
Therefore, the required system of inequalities contains some equations,
and
.
Consider the number 50,540.We have to determine the significant figure.
Significant figures are the digits that carry meaning contributing to its measurement resolution. It excludes the leading and trailing zeroes.
The first zero in the 50 is considered to be a significant number, while the second zero (in the 540) is not significant number.
The second zero is a called a placeholder zero. It can be removed by converting the number into scientific notation.
Answer:
v = - 1
Step-by-step explanation:
Collect like terms on the right side of the equation
3 = - 3v ( divide both sides by - 3 )
v =
= - 1
A+ny = n
a = n-ny
a = (1-y)n
a/(1-y) = n
