Answer:
x = -1.5
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.2x + 1 = 1.6x + 3.1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 0.2x on both sides: 1 = 1.4x + 3.1
- Subtract 3.1 on both sides: -2.1 = 1.4x
- Divide both sides by 1.4: -1.5 = x
- Rewrite: x = -1.5
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitution: 0.2(-1.5) + 1 = 1.6(-1.5) + 3.1
- Multiply: -0.3 + 1 = -2.4 + 3.1
- Add: 0.7 = 0.7
Answer:
So 3x = x +8 is your equation
We adjust the equation to isolate the x and we end up with 2x = 8
We have to isolate the x even more to turn it into x = 4.
So our final answer is x = 4
Answer:
The regular price for 1 pound of flour was $ 1.29
Step-by-step explanation:
Price Percentage
$ 16.24 90
x 100
***************************
90 * x = 16.24 * 100
90x = 1,624
x = 1,624/90
x = 18.05
Now, let's calculate the price of each bag of flour, this way:
Price of each bag = 18.05/7
Price of each bag = $ 2.58 (rounding to the next cent)
Finally, we can calculate the regular price for 1 pound of flour:
Regular price for 1 pound of flour = 2.58/2
Regular price for 1 pound of flour = $ 1.29
