The range is just the distance between the biggest number
and the smallest one.
The biggest number on that list is 350 .
The smallest number on that list is 75 .
The range is from 75 to 350, or a distance of 275 .
X=2W+1-1/Y
YOU SUBTRACT 2/Y TO START TO GET X ALONE.
WHICH WOULD MAKE IT 2X=4W+2-2/Y.
THEN YOU MUST DIVIDE BOTH SIDE BY TO FINISH GETTING X ALONE WHICH WOULD GIVE YOU YOUR ANSWER
Answer:
x = 26
Step-by-step explanation:
There are two numbers and average is the sum of a certain amount of numbers divided by the same amount.
21 × 2 = 42
42 - 16 = 26
x = 26
The first one is correct :-)
Answer:
25
Step-by-step explanation:
Since triangle DBC is isosceles, angles DBC and DCB must be congruent. Angle BDC is 40 so the sum of the measures of the aforementioned angles must be 180 - 40 = 140; divide that by two and you get that the measure of angle DBC is 70. Angles DBC and ABD are supplementary, as they lie on a straight line, so we can deduce the measure of angle DBA is 180 - 70 = 110. The measure of angle DAB is 180 minus the measures of angle DBA and ADB, we figured out angle DBA is 110 degrees and the problem tells us angle ADB is 45 degrees, so we can subtract to get the measure of angle DAB to be 180 - (110 + 45) = 25.
