One bag of rice that weighs 4.5 pounds will have enough rice if a recipe calls for 60 ounces of rice. (1 pound = 16 ounces)
dimulka [17.4K]

Answer:

Step-by-step explanation:

Since the bag of rice is 4.5 pounds, and there are 16 ounces per pound, multiply 16 x 4 = 64. Now what is half of 16? 8! So divide 5/8 = 0.625.

So in the end, yes the bag of rice will have enough rice. Here's my math:

16 x 4 = 64

5 / 8 = 0.625

So, you will have 64.625 ounces of rice which is plenty for your recipe!

(Please help I don't know how to do this)
mihalych1998 [28]

Answer: See step-by-step below.

Step-by-step explanation:

First we need to solve the equation, 16x + 16x - 1 = 10.

16x + 16x - 1 = 10

32x-1 = 10

Whatever we do on one side, we have to do on the other.

So, we will add 1 to both sides.

32x - 1 + 1 = 10 + 1

Simplify.

32x = 11

x = 11/32

So, 22x = 22(11/32)

= 121/16

 =  7 9/16

What is the anwser to 5/10 - (-8/10)? I really need to know if this fraction would be a negitive?
balandron [24]
<u><em /></u>Subtracting a negative number really means to add it

Here's addition:
(1) + (1) = 2
(1) + (-1) = 0
(-1) + (-1) = -2
(-1) + (1) = 0

Here's subtraction:
(1) - (1) = (1) + (-1) =0
(1) - (-1) = (1) + (1) = 2
(-1) - (-1) = (-1) + (1) = 0
(-1) - (1) = (-1) + (-1) = -2


Here's your problem specifically:

(5/10) - (-8/10)

(5/10) + (8/10)

*since they have the same denominator, that stays the same, and you only have to add up numerators

(5 + 8)/10

13/10

<u><em>answer is 13/10 . . . it's positive</em></u>
