Answer:

x=4

Step-by-step explanation:

-8-x=x-4x

Combine like terms

-8 -x =-3x

Add x to each side

-8 -x+x = -3x+x

-8 = -2x

Divide each side by -2

-8/-2 = -2x/-2

In an experiment, Plant 1 receives 10 grams less food than Plant 2. Plant 2 receives 3/5 the amount that Plant 3 receives. If Plant 3 receives 30 grams of food, how many grams of food does Plant 1 receive?

Answers

Well if plant 2 receives 3/5 of plant 3, which is 30 grams. You multiply 3/5 by 30 and you should get 18 grams. Now that is plant 2, and since plant one receives 10 grams less you just subtract 10 from 18 and you get 8.
Plant 1 receives 8 grams of food.

Final answer:

To determine the food received by Plant 1, first calculate Plant 2's food based on Plant 3's amount (30 grams * 3/5), yielding 18 grams. Then, subtract 10 grams (because Plant 1 gets 10 grams less than Plant 2) to find that Plant 1 gets 8 grams of food.

Explanation:

To solve this problem, we start by finding out how much food Plant 2 receives. Since Plant 2 gets 3/5 of the food that Plant 3 receives, and we know that Plant 3 gets 30 grams, we find out Plant 2's food amount by doing a multiplication of 30*(3/5), giving us 18 grams.

Next, we need to consider how much Plant 1 receives in comparison to Plant 2. The problem states Plant 1 gets 10 grams less than Plant 2. So, if Plant 2 receives 18 grams, then Plant 1 must receive 18 - 10 = 8 grams.

In summary

Plant 1 receives 8 grams of food based on the data provided in the problem.

If Julie needs 3 1/4 cups of oat meal how many 1/4 cups of oatmeal will she use ?

Answers

Basically, you divide 3 1/4 by 1/4. To do that, you have to change the mixed number into an improper fraction. 3 1/4 as an improper fraction is 13/4. I was able to find that since you simply just multiply the denominator by the whole number, 4 x 3, which is 12, then add 12 to the numerator, 1, which is 13. Finally, the improper fraction is 13/4 (the denominator stays the same). Now, we can divide the fractions. One rule about fractions: dividing them is the same as multiplying them with the reciprocal of the other. Like say for example, the reciprocal of 1/5 is 5/1. 

Let's solve:

13/4 divided by 1/4 =
13/4 x 4/1 = At this point, you just multiply them straight across.
52/4 = It's not simplified since both can still be divided. So, you simplify by finding the greatest common multiple of 52 and 4, which is 4. 52 divided by 4 = 13; 4 divided by 4 = 1. 
52/4 = 13/1 = 13 (any numerator with the denominator of one is a whole number when simplified)

So if Julie needs 3 1/4 cups of oatmeal, she will use 13 of 1/4 cups of oatmeal. Answer's 13. :) I really hope I helped!
