Let's create an equation
Move variable to L.H.S and change its sign
Similarly, move constant to R.H.S and change its sign
Calculate
Change the sign on both sides of the equation
Hope this helps..
Best regards!!
The formula for area of a trapezoid is: 1/2 (b1+b2) h
b1=10
b2=10·2=20 because it stated the side parallel is twice as long as the side above
h=10/2=5 because the height is half as long as the give side length
area of the trapezoid is: 1/2 (10+20) 5
(5·10)·5
50·5
area of the trapezoid is 250 in²
Let the marks of the students in class 1 be
the average of these 12 marks is 90, so
which means
similarly, let
be the marks of the students in the second class,
so
which means
The 32 students averaged:
The answer is 7, 2(7x5) + 2(4x7) + 2(5x4) = 166
5k^2 = 25 ^ 3 = 15625
5k^6 = 15625
Hope this helps
