Step-by-step explanation:
Answer:
1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let
be equal to the cost of 1 haircut.
Let
be equal to the cost of 1 colouring treatment.
<u>1) Form equations</u>
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒ 
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒ 
<u>2) Solve the system of equations</u>
Subtract equation 2 from equation 1 to cancel out y (elimination)
-
⇒ 
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y

Subtract both sides by 94

Therefore, Natalie charges 98 dollars for 1 colouring treatment.
I hope this helps!
C= total cost
d= number of days
r= rental cost
C= r * d
C= rd
Example:
If it cost $10 per day and you rented for 5 days, the total cost would be:
C= ($10)(5)
C= $50
Hope this helps! :)
Answer:
(m⁴-n⁴)
(m²+n²)(m²-n²)
(m²+n²)(m+n)(m-n)
<h3>3)
<u>(m²+n²)(m+n)(m-n)</u> is the right answer.</h3>
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.
<h3>What is the average speed of the train?</h3>
Given that;
- Distance traveled d = 75miles
- Time elapsed t = 46 min
- Average speed s = ?
Average speed = distance traveled / elapsed time
Average speed = 75miles / 46min
Average speed = 1.63 miles per minutes
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.
