First round the numbers to the nearest hundred.
339 --> 300
123 --> 100
Add them together.
300 + 100 = 400
Now add the tens places.
339 --> value of second 3 = 30
123 --> value of 2 = 20
30 + 20 = 50
Now add the ones.
9 + 3 = 12
Add all of these numbers together for your final number.
400 + 50 = 450
450 + 12 = 462
339 + 123 = 462
It is $0.65 because 6 divided by $9.30 is $0.645 and that rounds up to $0.65 :)
Answer:
x = -8
Step-by-step explanation:
5(x - 1) = -45
5x - 5 = -45
add 5 to each side of the equation:
5x = -40
divide both sides by 5:
x = -8
