**Answer: 7/8**

**Step-by-step explanation:**

**Answer:**

1.72973 oz/serving. Perhaps round to 1.73 oz, although there is only 1 sig fig in "4-pound bag." But the problem states "exactly."

**Step-by-step explanation:**

We want oz/serving, so let's convert the pounds of rice to total ounces of rice:

We are told that 16 oz = 1 pound. Make that a conversion factor: (16 oz/1 pound)

(4 pounds)*((16 oz/1 pound) = 64 ounces

We are told that 4 pounds (64 ounces) makes 37 servings. So:

(64 ounces)/(37 servings) = 1.72973 oz/serving

**Answer:**

just keep in mind am not sure if the answer 6:15:20

**Step-by-step explanation:**

now we have ab= 2 : 5

and bc= 3 : 4

so b is the common one between them so multiply both of the b together which will give u 15 so now we have b = 15

to get a multiply 2 by 3 to get 6 so a = 6

to get c multiply 4 by 5 to get 20 so c = 20

now I hope that its correct and that u understood

**Answer:**

-7x(x + 4)

**Step-by-step explanation:**

Not sure exactly what you're doing with this, but I know you're not solving it for x because there's no " = " there so I am assuming you're simplifying it as much as possible. I'm going with that.

First thing is to distribute through the parenthesis by multiplying 4x by 3x and then 4x by -7 to get:

Now combine like terms to get

The last thing you could do now is pull out what's common between each of those terms which is -7x. When you do that, you're left with

-7x(x + 4)
