Answer:
35
Step-by-step explanation:
1. Write the equation
y = 1.245x - 3.684
2. Set y = 40, since that is the cost of the songs he purchased.
40 = 1.254x - 3.684
3. Add 3.684 to both sides
43.684 = 1.254x
4. Divide by 1.254
x = 35.0875502
Answer:
36
Step-by-step explanation:
i think im right about this
V = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.
Answer:
x = +-sqrt(3) and they are the actual solutions
Step-by-step explanation:
x^2/ (2x-6) = 9/(6x-18)
get a common denominator of 6x-18
x^2/ (2x-6) * 3/3 = 9/(6x-18)
3x^2/ (6x-18) = 9/(6x-18)
since the denominators are the same, the numerators must be the same
3x^2 = 9
divide by 3 on each side
x^2 = 3
take the square root of each side
sqrt(x^2) = +-sqrt(3)
x = +-sqrt(3)
i think its C im half of one hundered % sure its that
