Can someone help with this?

Answer:

The answer to 28 is D. The answers for question 24 and more are below.

Step-by-step explanation:

24. 5 x 3/4 = 15/4

25. -2 x 8/3 - 16/3 (Multiply the numerator, cannot be divided by the denominator without being a mixed number)

26. 24/72 = 1/3 (simple multiplication and division, in this case both the numerator and denomator multiply each other)

27. 15/12 (again, simple multiplication.)

Answer:

-m - 3n + 12

Step-by-step explanation:

Because we don't know the values of "m" and "n"  the simplest form you can get the equation to be is -m + - 3n + 12

That is because with a negative in front of the parenthesis it's like multiplying by negative 1. So -1 x m, -1 x 3n, and -1 x -12.

Answer: 65

Step-by-step explanation:

Answer: 20 would be in the column for 2, and 60 would be in the column for 6.

Step-by-step explanation:

Answer:

none

Step-by-step explanation:

The first step you have to do is add 15 to both sides

so 12b > 36

next, you want to find out what b is so divide both sides by 12

b>3

As you represent this, you first want to find a line that is greater then three

this would be a because it is the only option that is greater then 3

However, because the dot is closed it can't be A so none of those options are correct

Tips:

if you are having trouble figuring out which lines are which remember that if the variable is on the left side of the equation to look at the sign. if you look at the sign then you see that the way the sign is going is also the way the arrow at the end of the line is going, but this trick only works if the variable is on the left side.

closed circle=≤, ≥

open circle= < , >

Answer:

Step-by-step explanation:

Given function f(x), when you want to find f(4) you just put 4 for every x in the equation of the function.

f(x) = 3x + 5    ⇒    f(4) = 3(4) + 5 = 12 + 5 = 17

g(x) = 2x² - 4   ⇒    g(4) = 2(4)² - 4 = 2•16 - 4 = 32 - 4 = 28

h(x) = -3x - 9   ⇒    h(4) = -3(4) - 9 = -12 - 9 = -21

Answer:

15a + 12

Step-by-step explanation:

3*5a=15a

3*4=12

=15a+12

When rounding, if the digit in the one's place is higher than 5, you round up. If it's lower than 5, you round down.

She's closer to 370m. Since the runner is at 368m and the digit in the ones place is higher than 5, you have to round up to 370. This means the runner is closer to 370m.

All you have to do is put it into you calculator but make sure to use parenthesis.Ex:( 2^-3) x(2^-4) and that will give you your answer.

13. The first six is in the 600th place and the second six is in the 60th place

14. The first four is in the 4000th place and the second four is in the 400th place

15. When the same two digits are next to each other in a multi-digit number, it doesn't mean that they are both in the same place value spot. For example, the number of 4,456 has two fours in it. But the first four is in the 4000th place and the second is in the 400th place.

3. The first five is in the 50th place (or the 10s place) and the second five is in the 5th place (or the 1s place)

4. The first eight is in the 8000th place (or the 1000s place) and the second eight is in the 800ths place (or the 100s place)

5. Yes, that is correct. The first seven is in the 100th place and the second seven is in the 10th place. 100 is ten times more than 10.

6. No, the only difference in the two numbers is the numbers following the two first sixes.

Step-by-step explanation:

6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 = 2176782336

217678336  let me explain

Step-by-step explanation: You have to multiply 6 every 12 times

6 x 6 =36

36 x 6 =216

216 x 6 =1296

1296 x 6 =7776

7776 x 6 =46656

46656 x 6 =279936

279936 x 6 =1679616

1679616 x 6 = 10077696

10077696 x 6 = 60466176

60466176 x 6 = 362797056

362797056 x 6 = 2176782336
