Answer:
= - 
Step-by-step explanation:
Given
=
( cross- multiply )
2(a - b) = 3(a + 2b) ← distribute parenthesis on both sides )
2a - 2b = 3a + 6b ( subtract 3a from both sides )
- a - 2b = 6b ( add 2b to both sides )
- a = 8b ( divide both sides by 8 )
-
a = b ( divide both sides by a )

<span>Given:
family travelled 25 miles in 30 minutes or 50 miles /hr
current time 3.00 pm.
total distance=225 miles.
solution:
speed = distance * time
time = distance/spedd
= 225/50
time = 4.5 hours.
reaching time= 3 hours +4 hour 30 minutes= 7.30 pm</span>
Answer:
B
Step-by-step explanation:
To find how many hours she worked you must divide $65 by $5 and B is the only equation where you can do that.
For the answer to the question above asking to s<span>olve 1/2(4x + 6) = 1/3(9x - 24) with and without using the LCD of the fraction.
The problem is simple.
just multiply 1/2 to 4x + 6 which will result to 2x+3
same method on the 1/3 to 9x - 24 and it will result to 3x-8
2x+3 = 3x - 8
3x-2x = 8+3
then the answer will be x= 11</span>
