6/x=27
times both sides by x
6=27x
divide both sides by 27
6/27=x
2/9=x
the missing number is 2/9
5x + 10 = -4x - 17
+4x +4x
5x + 4x = 9x
9x + 10 = -17
-10 -10
-27
9x = -27 9x/9 = -27/9
x = -3
Direct variation is of the form y=kx (inverse variation is of the form y=k/x)
Answer:
congruent angles have same number of shape and size
A = 1/2h(b1 + b2)
A = 1/2*9.28(10.5 + 21.1)
Using calculator
A = 146.624 square cm
