Answer:
20
Step-by-step explanation:
To work out the average, you add all the terms and divide that by the number of terms there are.
64 + 63 = 127
127 ÷ 2 = 63.5
The answer is 63.5.
However, because these are only two consecutive integers, you just add 0.5 to find the average. e.g: average of 2 and 3 = 2.5, average of 3 + 4 = 3.5, average of 6 + 7 = 6.5 etc... Remember, this only works if there are only two integers and they are consecutive.
The answer is 15.
Using the distance formula you’d get. Sqrt(-2-7)^2+(-10-2)^2
Sqrt(-9)^2+(-12)^2
Sqrt(81+144)
Sqrt(225)
D=15
Answer:
f(3) = 7
Step-by-step explanation:
f (x)=x + 4
Let x=3
f (3)=3 + 4
f(3) = 7
Answer:
because angles on a straight line add up to 180 degrees substract (180-110), step 2; you will get 70 degrees afterwards the angle y is perpendicular it's 90 degrees.step 3;add (90+70) you get 160 .step 4;then substract (180-160) you get your answer as 20 degrees
