Answer:
Total length after 33 days will be 117 miles
Step-by-step explanation:
A construction crew is lengthening a road. The road started with a length of 51 miles.
Average addition of the road is = 2 miles per day
Let the number of days crew has worked are D and length of the road is L, then length of the road can represented by the equation
L = 2D + 51
If the number of days worked by the crew is = 33 days
Then total length of the road will be L = 2×33 + 51
L = 66 + 51
L = 117 miles
Total length of the road after 33 days of the construction will be 117 miles.
Because the number has to have no greater divisors other than one or itself
The system of equations provides a unique solution(one solution) at (-0.6, 1.6).
<h2>Given to us,</h2>
<h3>Equation 2</h3>
As we already have the value of y from equation 1, substitute its value in equation 2,
<h3>Equation 1,</h3>
substitute the value of x in equation 1,
As we can see the system of equations provides a unique solution(one solution) at (-0.6, 1.6).
