i have a few problems can you check?

1. which number is 1.92509 rounded to the nearest ten - thousandths?
a 1.9251 b. 1.9250
c. 1.93000 d. 1.90000
i picked a. 1.9251

#6 which of the following is in order from least to greatest?
f. -9, -5, 0, |-2|
g. |-5|, -4, 2, 6.7
h. 1.5, 0.9, -4, -6
i. -1, 0 , -0.3, 7

#7 evaluate -3 - (-9) +4
a. -10
b. -8
c. 10
d. 8
i picked c 10

#8 solve the equation -9x = -72
i got: 8

#9 solve x/5 + 8 = 3
i got: -25

#11 order these fractons from least to greatest
2/5 , 1/3, 3/8

i got: 3/8, 1/3, 2/5

#6 would be f)

rest are correct

Let's go through each of your problems and check your answers:

1. To round the number 1.92509 to the nearest ten-thousandths, we look at the digit in the fifth decimal place. Since it is 0, which is less than 5, we don't need to round up. Therefore, the correct answer is b. 1.9250.

6. Let's compare the given options from least to greatest:

f. -9, -5, 0, |-2| --> |-2| is equal to 2, so the order becomes -9, -5, 0, 2.
g. |-5|, -4, 2, 6.7 --> |-5| is equal to 5, so the order is 5, -4, 2, 6.7.
h. 1.5, 0.9, -4, -6 --> The order remains the same.
i. -1, 0, -0.3, 7 --> The order remains the same.

Comparing all the orders, the correct answer is f. -9, -5, 0, 2.

7. To evaluate -3 - (-9) + 4, we follow the rules of operation (BIDMAS/PEMDAS) and evaluate the expression step by step.

-3 - (-9) + 4 = -3 + 9 + 4 (since double negatives cancel out)
= 6 + 4
= 10

So, the correct answer is c. 10.

8. To solve the equation -9x = -72, we need to isolate x by dividing both sides of the equation by -9.

-9x = -72
x = (-72)/(-9)
x = 8

So, the correct solution is x = 8.

9. To solve the equation x/5 + 8 = 3, we need to isolate x by performing operations that will isolate the variable. Let's solve it step by step:

x/5 + 8 = 3
x/5 = 3 - 8
x/5 = -5
x = -5 * 5
x = -25

So, the correct answer is x = -25.

11. To order the fractions 2/5, 1/3, 3/8 from least to greatest, we can compare them by converting them into fractions with a common denominator.

Multiplying each fraction so that the denominators become 40, we get:
2/5 = 16/40
1/3 = 13/40
3/8 = 15/40

Now, comparing the fractions, the order is 13/40, 15/40, 16/40.

So, the correct order is 1/3, 3/8, 2/5.

Overall, your answers for problems 1, 6, 7, 8, 9, and 11 are incorrect.
