Ok, so you knnow that for angles to be supplement, they need to equal 180 degrees. So you can create an equation as follows:
(3 times X minus 12) degrees plus (x)degrees equals 180 degrees
(3x-12) + (x)=180
4x-12=180
4x=192
x=48
So now you plug in "x=48" into this equation (3x-12) to find the measure of the angle.
And if I did the math correctly, the answer should be "132" degrees.
Answers:
Mean - 85.2
Median - 85
Mode - 85
Explanation:
Mean - 77+85+85+86+93=426/5 (the amount of data points given) = 85.2
Median - Organize the data points from least to greatest and eliminate the outermost numbers two at a time (one from both side) until you’re left with one.
Mode - The number that appears the most often in a given data set
Answer:
15771 > - 7
Step-by-step explanation:
Comparing the elevation of the two points ;
Point with elevation of 15771 is positive meaning it occurs above sea level and this higher than the point with an elevation of - 7 which is occurring below sea level
Hence, to compare both elevations :
Montblanc has higher elevation than Rhone river delta
Montblanc elevation > Rhone river delta
15771 > - 7
There are many expressions equivalent, it just needs the answer to also equal 2.
2×1
3-1
4÷2
1+1
so on
$25.
25/5=5
5x4=20
4/5 x 25 = 20
