Answer:
x = -11
Step-by-step explanation:
0.2(20x + 10) = -42
4x + 2 = -42 Distribute 0.2 to the numbers in the paranthesis
4x = -44 Add 2 to both sides
x = -11 Divide 4 from both sides
Answer:
The answer is -0.5
Step-by-step explanation:
Divide both side by the numeric factor on the left side then solve
27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)
27pi=84.823
rounded, 84.82
