First, we should change the first two into percentages to make ordering them easier-

Do 21/25, which equals .84 ; you then move the decimal a couple places to get 84. That’s 84%.

Next, do the same steps to find the percentage of 25 out of 27; you would get 92.6 (rounded from 92.59)

So, knowing the percentages of those two, you can now order them from greatest to least, which would be as following:

25/27, 92%, 88%, and 21/25.

Hope that helped!

A physically active adult weighing 185 pounds needs to consume about 2830 calories per day in order to maintain his or her weigh
Vitek1552 [10]

Answer:

A maximum of 990 calories per day should come from simple sugar.

Step-by-step explanation:

Given:

Calories consumed per day = 2830

A nutritionist recommends that no more than 35​% of those calories should come from simple sugars.

Let the number of calories come from sugar be x;

Hence,

x\leq 35\% \ of \ given \ calories

x \leq \frac{35}{100}\times 2830\\\\x\leq 0.35\times 2830\\\\x\leq 990.5

From above we can say that x should be less than or equal to 990.5 hence we can say x is 990 calories

Hence A maximum of 990 calories per day should come from simple sugar.

Write the equation in function form<br> 6y - 4x = 24
k0ka [10]

Answer:

f(x) = (2/3)x + 4

Step-by-step explanation:

An equation in function is found by isolating y, and changing "y" to "f(x)".

Isolate y by moving everything else to the other side

What is done to one side must be done to the other

6y - 4x = 24

6y - 4x + 4x = 24 + 4x          (add 4x to both sides. -4x +4x cancels out)

6y = 24 + 4x

6y/6 = 24/6 + 4x/6             (divide both sides by 6)

y = 4 + (2/3)x          (simplify)

y = (2/3)x + 4        (rearrange to a familiar format "y=mx+b")  

f(x) = (2/3)x + 4        (replace y with f(x))

There are 165 laptops and desktop computers in a lab. There are 9 more laptops than desktop computers. What is the total number
Alina [70]

Answer:

87

Step-by-step explanation:

Let d = number of desktops.

Let a = number of laptops.

a + d = 165

a = d + 9

d = a - 9

a + d = 165

a + a - 9 = 165

2a - 9 = 165

2a = 174

a = 87

Answer: 87

Solve this equation. (3x+10)−(2x−9)=43
Rus_ich [418]

Answer: X = 24

Step-by-step explanation:

Move all terms to the left:

(3x + 10) - (2x - 9) - 43 = 0

Get rid of all the parenthesis:

3x + 10 - 2x - 9 - 43 = 0

Add all the numbers and all variable:

x-24 = 0

Move all terms containing x to the left and all other terms to the right:

x = 24
