(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
Answer:
Step-by-step explanation:
First, you need to find the GCF of both denominators.
That would be 21.
You would need to multiple the 7 in 4/7 by 3, to get to 21. That means you would also have to multiply 3 by the 4. You should get 12/21.
Do you same thing to 1/3.
After that you should get the 2 factions, 12/21 and 7/21
12/21 + 7/21 = 19/21
There isn't anyway to simplify it, meaning the final answer is 19/21.

Hello!
Equation D. t = 12c shows how many bottles of water Josh bought.
Explanation:
The first three equations would NOT give you the answer, because if you divide, you'll find out how many bottles are in each case.
If you subtract and add, it'll also result in the wrong answer, so D is the right equation.
