Answer:
Solution:
Explanation:
The goal is to solve the system by substitution following these steps:
- 1. Isolate the variable with the smallest coefficient, moving the term with the lowest coefficient so that it is alone one one side
- 2. Divide by the coefficient
- 3. Substitute
- 4. Solve
This is the application of those steps to the given system:
<u>1. Isolate the variable with the smallest coefficient:</u>
<u>2. Divide both sides by the coefficient</u>
<u>3. Substitute</u>
- 3 × [2 - 5D] / 2 + 4D = 5
<u>4. Solve</u>
- Distributive property: multiply 3 with each term inside the brackets
(6 - 15D) / 2 + 4D = 5
- Distributive property: divide each term inside the parenthesis by 2:
3 - 15D/2 + 4D = 5
- Move the number 3 to the right side (addition property of equality)
- 15D/2 + 4D = 5 - 3
- Combine like terms (add the fractions on the left and the constant terms on the right)
[- 15D + 8D] / 2 = 2
[-7D] = 4
D = - 4/7
C = [2 - 5D] / 2 = [2 - 5 (-4/7) ] / 2
C = [2 + 20/7] / 2
C = [14 + 20] / 14
C = 34 / 14
C = 17 / 7
Solution:
Answer:A powder is an assembly of dry particles dispersed in air. If two different powders are mixed perfectly, theoretically, three types of powder.
Explanation:
It channels erode wider fed by many tributaries and has more discharge and is less steep
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
