The average will always be 48. No matter what the numbers are, they will equal 144 and there will always be 3 numbers so you divide 144 by 3 and that equals 48.
Answer:
2⁹
Step-by-step explanation:
Using the rule of Indices:
aⁿ x aˣ = aⁿ⁺ˣ
Hence: 2²⁺³⁺⁴
= 2⁹
M∠DAB + m∠ABC = 180°
m∠DAB + 72° = 180°
Subtract 72° on both sides.
m∠DAB = 180° - 72°
m∠DAB = 108°
Your final answer is B. 108°
Answer:
85°
Step-by-step explanation:
The exterior angle of a triangle is=sum of the opposite interior angles
So
? °=45°+40°
Answer:
-5/6
Step-by-step explanation:
A great way to divide fractions is to use the "leave it, change it, flip it" method. You leave the first fraction as it is, change the division sign to a multiplication sign, and flip the second fraction so you get the reciprocal. Like this:
-5/7 ÷ 6/7
-5/7 x 6/7
-5/7 x 7/6
Then you multiply through. First -5 x 7, -35, and then 7 x 6, 42, to get -35/42. Because both of these are divisible by 7, we can simplify to get -5/6.
