Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 2/3x + 4
2x - 3y = -12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 3(2/3x + 4) = -12
- Distribute -3: 2x - 2x - 12 = -12
- Combine like terms: -12 = -12
Here we see that -12 does indeed equal -12.
Therefore, our <em>x</em> would equal infinite amount of solutions.
<u>Step 3: Graph systems</u>
<em>Check the systems.</em>
We see that the 2 lines are the same.
Answer:
Step-by-step explanation:
when you are taking (4/10) and dividing it by 2. you have a fraction over a fraction. if you remember what you do to the top part of the equation you do to the bottom. so we want to get rid of dividing by 2. (multiple by the reciprocal) the reciprocal of 2 is 1/2. that will cancel out the bottom part of the equation but what you do to the bottom you have to do to the top. so, (4/10) * 1/2 is the same as (4/10) divided by 2. hope that makes sense. it's much easier to write out then type math...
Answer:
15 Poses
Step-by-step explanation:
SInce he can teach 30 poses in 60 minutes and if the class time is cut by half then the poses are cut by half. Look below.
Minutes : 60/2 = 30 minutes
Poses : 30/2 = 15 poses
