Answer:
1000 rounded to the nearest ten is:
1000
Step-by-step explanation:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

answers
question 1 = -0.5
question 2 = 6 - 3y
question 3 = 3x + 6
question 1
to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation
(x + 1)/3
= (-2.5 + 1)/3
= (-1.5)/3
= -0.5
question 2
to solve this, distribute the 1/2 through the parentheses
(1/2) * (4 − 6y + 8)
= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)
= 2 + (-3y) + 4
= 6 - 3y
question 3
to solve this, distribute the 3 through the parentheses
3(x + 2)
= (3 * x) + (3 * 2)
= 3x + 6
<em>note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions</em>
