$30/2=$15.
She charges $15 for one hour
Therefore, she must charge $75 for 5 hours
<h3>The solution as an ordered pair is (x,y) = (2,2)</h3><h3>x = 2 and y = 2 pair up together.</h3>
===============================
Work Shown:
4x+2y = 12
4x+2( y ) = 12
4x+2( 2x-2 ) = 12 ... replace y with 2x-2
4x+2( 2x ) + 2( -2 ) = 12 ... distribution rule
4x+4x-4 = 12
8x-4 = 12
8x-4+4 = 12+4 ... add 4 to both sides
8x = 16
8x/8 = 16/8 ... divide both sides by 8
x = 2 is the first part of the answer
Use x = 2 to find y
y = 2x-2
y = 2(2)-2 ... replace x with 2
y = 4-2
y = 2 is the second part of the answer
Answer:
A
Step-by-step explanation:
Since each star is worth 50 points, if 5 stars are zapped that would convert to 250 points. Each level the number of stars increase by 5, level 6 would have 45 stars and so on.. With level 10 having 65 stars to complete.
Eight less than the product of 2 and a number x is: 2x-8
