7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6
(-24z^2) / (6z)
Simplifies to -4
Answer:
A) 5 7/10 =7/2 = 3.5
B) 5 28/33 = 140/33 = 4.24...
this one is correct - C) 5 26/33 = 130/33 = 3.93...
D) 5 39/50 = 39/10 = 3.9
5.78 =5 71/90
5.78 =5 26/33
2-4 is -2 and -5 times -2 is 10 divided by 2 is 5 and 5 +3 is 8. and 8 times 3 is 24. PEMDAS
