Answer:
Step-by-step explanation:
You simply need to substitute the numbers in the x column into the equations in the topmost row. The answers are the values of a, b, c, d, e, and f.
Look at the filled in cells.
In the x column, we have -2, and the topmost row we have . The answer is given as . This is because
Repeat this for the values that you need to find.
Answer:
What question? We need more context
<u>Reasoning </u><u>:</u><u>-</u>
- & - together will give you +
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
7 1/20 = (7×20)+1 = 140+1 = 141/20.
It will be 7.??
1/20 = 20 into 1.000: 20 goes into 100 5 times, so that's. 0.050
Now tack onto 7 = 7.050
