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:

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:It doesn't make sense when I try to do it,I even tried a calculator

Step-by-step explanation: IDK?

Answer:

subtract 2.9 from 3.8 you get 0.9

subtract 1.0 from 1.9 you get 0.9

subtract 1.9 from 2.8 you get 0.9

subtract 1.8 from 2.9 you get 01.1

I would say that your answers are E, C, and B.

Answer:

B, C, and E

Step-by-step explanation:

If you subtract 2.9 from 3.8 you get 0.9 so if u apply that to B, C, and E, you could add 0.9 to 0, 1.0, and 1.9 and get the equations:

0+0.9= 0.9

1.0+0.9= 1.9

1.9+0.9= 2.8

so as you can see it all just increases by 0.9 every time.

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.

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.

Answer:

Step-by-step explanation:

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:

Question 1: 15 cups

20% (pineapple juice) = 3 cups, 100/20=5, 5*3 = 15 cups

Question 2:  20 cups
