To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Explain the mistake 3/6 + 1/3 = 4/9
Shkiper50 [21]

Answer:

The answer should be 5/6

Step-by-step explanation:

The problem just adds both the numerator and the denominator which is something you can't do. You have to find the least common denominator, which in this case is 6, and change the numerator as the denominators have been changed. So 1/3 becomes 2/6. 3/6 + 2/6 = 5/6

Where mBD =70° and mCA = 170°
Nookie1986 [14]

Answer:

m∠BPD = 120

mBC + mAD = 120°

Step-by-step explanation:

according to intersecting chord theorem: The measure of the angle formed by two chords  that intersect inside the circle is \frac{1}{2} the sum of the chords' intercepted arcs.

m∠BPD = \frac{1}{2} (M∠BD + M∠CA)

             = \frac{1}{2}  (70 + 170)

             =  \frac{1}{2} (240)

m∠BPD = 120

We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°

mBC + mAD = 360 - ( 70 + 170 )

                     = 360 - 240

mBC + mAD = 120°
