= 49π
= 153.938040026 → 154 cm²
Answer:
A. 1
Step-by-step explanation:
3(x+1)=-2(x-1)+6
3x+3=2x-2+6
x+3=4
x=1
Answer:

Negative numbers are always less than positive numbers. 3/10 is less that 1/4:
Making the answer c.
Answer:
1/2
Step-by-step explanation:
to solve this equation you must find the greatest common factor or gcf to make the denominators the same
that happens to be 6
so
-4 5/6 + 5 2/6
then you add
you can break them up at add them like this
(-4 + 5) + (-5/6 + 2/6)
1 + -3/6
-3/6 is also -1/2
1 + -1/2
1/2
that is your answer
