I believe that it might be 15x+9
Answer:
A= 40
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3/4 (2a-6)+1/2=2/5(3a+20)
(3/4) (2a) + (3/4) (-6) + 1/2 = (3a) + (2/5) (20)
(distribute)
3/2a + -9/2 + 1/2 = 6/5a + 8
(3/2 a) + ( -9/2 + 1/2 ) = 6/5a + 8 (Combine like terms)
3/2a + -4 = 6/5a + 8
3/2a -4 = 6/5a+8
Step 2: Subtract 6/5a from both sides.
3/2a - 4 - 6/5 a = 6/5a + 8 - 6/5 a
3/10 a - 4= 8
Step 3: Add 4 to both sides.
3/10a -4 +4 = 8 + 4
3/10 a = 12
Step 4: Multiply both sides by 10/3
(10/3) * (3/10a) = (10/3) * (12)
a = 40
5.18 lbs - 3.76 lbs = 1.42 lbs

6 computer R not working
24 Computers in total
Turn into fraction
6/24 (6 Top) (24 bottom)
Then simplify by 6
6 Divided By 6 is 1
24 Divided By 6 is 4
1/4 (1 top) (4 bottom)
Convert to decimal= 0.25
Move Decimal Point to the right two times
And that would get you 25%
