(5 + 7x + 6)/2 = 3x + 9
7x + 11 = 6x + 18
7x - 6x = 7
x = 7
EF = 3x + 9
= 3(7) + 9
= 21 + 9
= 30
Answer:
49.2°
Step-by-step explanation:
To solve for x you'll need to find the cosine of x°.
To find the cosine you will need to divide the adjacent side to it by the hypotenuse.
cos x°= 
Using a calculator to solve you'll get that x ≈ 49.2°
Answer:
the last on bottom right :)
Step-by-step explanation:
1/2 of 2 is 1
1/2 of 10 is 5...
5:1
I'm gonna assume that the 5s are $.
To find the mean, add all the numbers, then divide by the number of data points (5).
(2426+2463+1451+2154+1119)/5 = 1922.6
To find the median, put the data in order from least to greatest, then find the middle data point.
1119 1451 2154 2426 2463
To find the range, subtract the largest from the smallest:
2463-1119 = 1344
