Step-by-step explanation:
Step 1: Define Equation
6n + 7 = 55
Step 2: Solve for n
Subtract 7 on both sides: 6n = 48Divide 6 on both sides: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 6(8) + 7 = 55Multiply: 48 + 7 = 55Add: 55 = 55Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.

what type of solution is y=5x+4+5x-2
The type of solution to the given simultaneous equations is no solution
What is the solution to the simultaneous equations?When it comes to linear simultaneous equations as given in the question, there are different types such as; one solution, no solution or infinitely many solution.
We are given the simultaneous equations;
y = 5x + 4 ---(1)
y = 5x - 2 ----(2)
Using elimination method, subtract eq 1 from eq 2 to get;
0 = -2 - 4
0 = -6
0 cannot be equal to -6 and as such there is no value of x that makes the simultaneous equations true. Thus, the type of solution to the given simultaneous equations is no solution

in exercises 13–17, the position d of a bicyclist (measured in kilometers) is a linear function of time t (measured in minutes). at time t
The position of the bicyclist at t=8 minutes is 3.2 km
Speed is the rate of change of position of an object in any direction.
position the way in which something or someone is placed or arranged.
when time t = 6 position d = 5
when time t = 5 position d = 2
when time t = 8 position d = x
therefore we can say
8 / x = 5 / 2
x = 8 * 2 /5
= 3.2 km.
Hence the position of the bicyclist at t=8 minutes is 3.2 km.

The coordinates of the point

The coordinates of the point that is 3 / 10 of the way from point A to point B is C(x, y) = (0.9, - 3).
How to find the coordinates of a point within a line segment
In this problem we find a line segment whose endpoints are known: A(x, y) = (- 3, - 6), B(x, y) = (10, 4), and of which we need to find a point C such that it is 3 / 10 of the way from point A to point B, whose exact location can be found by means of the line segment formula:
C(x, y) = A(x, y) + (3 / 10) · [B(x, y) - A(x, y)]
C(x, y) = (- 3, - 6) + (3 / 10) · [(10, 4) - (- 3, - 6)]
C(x, y) = (- 3, - 6) + (3 / 10) · (13, 10)
C(x, y) = (- 3, - 6) + (3.9, 3)
C(x, y) = (0.9, - 3)
The coordinates of the point that is 3 / 10 of the way from point A to point B is C(x, y) = (0.9, - 3).
