X - 2y = -10 --> x = 2y -10
3x + 5y = 25 --> 3(2y-10) + 5y = 25 --> 11y - 30 = 25 --> 11y = 55 --> y = 5
x = 2y -10 --> x = 2(5) -10 --> x =10 -10 --> x =0
Answer (0,5)
Answer:
Infinite amount of solutions.
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Regular + Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
6y + 4 - 3y - 7 = 3(y - 1)
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms: 3y - 3 = 3(y - 1)
- Distribute 3: 3y - 3 = 3y - 3
- Subtract 3y on both sides: -3 = -3
Here we see that there will be infinite amount of solutions. We can plug in any number <em>y</em> and it will render the equation true.

You are bisecting angle BAC with pencil and compass.
The answer is :
23 3/8 can be written as 23.375
Answer:
$55.13
Step-by-step explanation:
50 * 1.05 = 52.5
<em>We do this step twice because the interest is for </em><em>2 years.</em>
52.5 * 1.05 = 55.125
<em>This rounds up to 55.13, your final answer!</em>
