Answer:
x = 3
Step-by-step explanation:
3x = 13-4
=> 3x = 9
=> x = 3
I think the answer is 5, if you divide 7.5 by 1.45 you get 5.2 or 5.17 so approximately 5.
Answer:
No real solution
Step-by-step explanation:
First off I'm assuming that the 1 or -1 at the begging is just the problem number:
First you distribute on both sides
36 - 18x - 3 = 4 - 18x + 30
Then combine like terms
33 - 18x = 34 - 18x
Then rearrange the terms by adding 18x to both sides and subtracting both sides by 33. You should get:
0 = 1
When you add positive 18x it cancels the -18x out. And 34 - 33 is 1. Obviously, zero cannot equal 1 so there is no real solution
Answer:
10/ 3
Step-by-step explanation:
3 × (48 xy) × 5/ (54 x y) × 4
3 × 48x y x 5/ 54 xy × 4
12 × 5/ 18
2 × 5 / 3
10/ 3
hope it helps!
It is the second one :1 is not in the domain of f*g
