In the year 2000 Detroit, Michigan had a population of 1,144,646. What is this population rounded to the nearest hundred thousand?

Answers

Answer 1

Answer: Step one is to find which number is in the hundred thousand's place. We can count right to left to find this out. 6 is obviously in the ones place, then 4 in the 10s, 6 in the 100s, 4 in the 1,000s, 4 in the 10,000s, and finally, a 1 in the hundred thousands. Now we know that the second one in the number, 1,144,646, is in the hundred thousands place. Look at the number right behind it, 4. If the number is 5 or higher, round up, if 4 or lower, round down. Since it's 4, you'd round it to 0, and round all the numbers behind it to 0. Your answer is 1,100,000

HelpIf 40 - x < 3x, then the solution is....
A. x < 20
B. x > 20
C. x > 10
D. x < 10
Thanks!

Answers

40 - x < 3x

Simplify both sides of inequality:

−x + 40 < 3x
Subtract 3x on both sides:

−x + 40 − 3x < 3x − 3x−4x + 40 < 0

Divide both sides by -4:

-4x/-4 < -40/-4

x > 10

C. x > 10

Solutions for 40 - x < 3x

To find the answer we have to solve the equation 40 - x < 3x.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

1) The first step is to add x to each side
40 < 3x+x

2) Next you simplify 3x+x. To simplify 3x+x you add the x to 3. 3x+x = 4x
40 < 4x

3) Divide both of the sides by 4
$(40)/(4)$ < x

4) Simplify the fraction $(40)/(4)$ to 10. You simplify it to ten because 40 ÷ 4 = 10.
10<x

5) Answer
x= > 10

The correct choice is C.
