Answer:
The solution is n=1
Step-by-step explanation:
I hope you mean
4/5n-3/5=1/5n
if so then here's the solution
5n×4/5n-3/5×5n=1/5n×5n
4-3n=1
4-1=3n
3n=3
n=1
Answer:
Step-by-step explanation:
Total cost
C (x) = 35+ 60x
Where,
Fixed cost= $35
Variable cost = 60x
x= number of hours of work
Total cost is the addition of fixed and variable cost
C (x) = 35+ 60x
C(5)= 35 + 60(5)
= 35 + 300
=335
C(5) = 335
C(5) = 335 is Olivia's total cost of hiring the electrician
x=5 is the electrician's number of hours of work
35= fixed cost of hiring the electrician
60(5) = 300 is the variable cost of hiring the electrician for 5 hours
An equivalent statement is CD overbar congruent to EF overbar.
What is a line segment?
The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.
Here,
Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.
So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.
Hence, An equivalent statement is CD overbar congruent to EF overbar.

When subtracting a number from a negative (like question one) the subtraction sign will now be an addition sign.
1.
6-(-7)=13
For question 2, its simple subtraction. If you subtract a negative from positive, it'l be a negative.
2.
-3 - 3= -6
3.
-15 - 23 = -38
Now we combine my previous explanations. Subtracting a negative from a negative will be like adding (like in question 4)
4.
-9 - (-5)= -4
5.
5 - (-15)=20
6.
78-(-17)=95
Extra Info:
When adding a number (doesnt matter if positive or negative) to a negative it will turn into subtraction.
Examples:
6+(-9)=-3
-9+(-9)= -18
Answer:
2,7
