Assuming that there is supposed to be a + sign in front of the 2 and 4; the answer is as follows.
3(x+2)+4(x-5)=10
3x+6+4x-20=10
7x-16=10
7x=16
x=2 2/7
Hope this helps :)
Area= 1/2abSinC where a and b are sides and c is an angle. All sides= 6 inches, all angles= 60°
1/2x6x6xSin(60)= 9√3 in2
E(t) is the elevation Maria is at at t minutes.
The expression to calculate the elevation is 1200 + 40t.
E(t) = 1200 + 40t
E(15) means the elevation Maria is at at time 15 minutes.
E(15) = 1200 + 40(15)
E(15) = 1200 + 600
E(15) = 1800
E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.
This is an incomplete question.
