Answer:
k=0.106383
Step-by-step explanation:
Let's solve your equation step-by-step.
12=4.7k+11.5
Step 1: Flip the equation.
4.7k+11.5=12
Step 2: Subtract 11.5 from both sides.
4.7k+11.5−11.5=12−11.5
4.7k=0.5
Step 3: Divide both sides by 4.7.
4.7k
4.7
=
0.5
4.7
k=0.106383
Answer:
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.
Use the quadratic formula with a = 2, b = -5, and c = 1
x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a
x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)
2(2)
x = 5 ± √17
---------

x = 5 + 1√17 OR x = 5 + -1√17

Answer: x = 5 + 1√17 OR x = 5 + -1√17

The three sides have the same length
Answer: 25 songs
Step-by-step explanation:
Cuz 1 song = 0.99
And total = 24.75
So if we divide the total by the per song cost = how many songs she downloaded
24.75/ .99 = 25
