-3/2
Step-by-step explanation:
you can use the rise over run method to find the slope of this line
The answer is c
The are of the trapezoid is c bc that’s the answer I got and it was right
30b + 100u = 900
5b + 25u = 200....multiply by -6
------------------
30b + 100u = 900
-30b - 150u = - 1200 (result of multiplying by -6)
------------------add
-50u = - 300
u = 6 <== upgrated phones sold
30b + 100u = 900
30b + 100(6) = 900
30b + 600 = 900
30b = 900 - 600
30b = 300
b = 10 <== basic phones sold
Measure the lengths of the runways in inches and then times your answer by 700 and then round that answer.
