Step-by-step explanation:
<u>Step 1: Define</u>
5 - 7(2 - x) = 31 - 4(2x - 5)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5 - 14 + 7x = 31 - 8x + 20
- Subtract/Add: -9 + 7x = -8x + 51
- Add 8x on both sides: -9 + 15x = 51
- Add 9 to both sides: 15x = 60
- Divide 15 on both sides: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 5 - 7(2 - 4) = 31 - 4(2(4) - 5)
- (Parenthesis) Multiply: 5 - 7(2 - 4) = 31 - 4(8 - 5)
- (Parenthesis) Subtract: 5 - 7(-2) = 31 - 4(3)
- Multiply: 5 + 14 = 31 - 12
- Add/Subtract: 19 = 19
Here we see that 19 does indeed equal 19.
∴ x = 4 is the solution to the equation.
You suppose to make the equation add each other I pretty sure so it be A.
Given:
The function are:
To find:
The function (f-g)(x).
Solution:
We have,
We need find (f-g)(x).
On combining like terms, we get
Therefore, the correct option is B.

Answer:
1200 copies
Step-by-step explanation:
We can use ratios to solve
480 copies x copies
------------------ = -------------
4 minutes 10 minutes
Using cross products
480* 10 = 4x
Divide each side by 4
4800/4 = 4x/4
1200 =x
