100 / 7.45 = 13.422818791... (7.45 x that number = 100)
13.422818791... x 5.51 = 73.9597315436... (makes 5.51 equal to 7.45, if you know what I mean)
100 - 73.9597315436 = 26.040268456...% (difference between 100(7.45) and 73.95...(5.51)) 
Answer - 26.040268456%
This is my answer. I THINK it is correct but I do not guarantee it. enjoy!

Someone pls answer this it’s so confusing lol

Answer:

<h2>y = \frac{w}{h -  {2c}^{3} }</h2>

Step-by-step explanation:

w = yh - 2yc³

First of all factorize y out of the expression on the right side of the equation

That's

w = y( h - 2c³)

Next divide both sides by (h - 2c³) to make y stand alone

We have

<h3>\frac{y(h -  {2c}^{3}) }{h -  {2c}^{3} }  =  \frac{w}{h -  {2c}^{3} }</h3>

We have the final answer as

<h3>y = \frac{w}{h -  {2c}^{3} }</h3>

Hope this helps you

Anvisha [2.4K]

Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.

<h3>What is the percentage increase of a value?</h3>

It is given by the increase divided by the initial value, and subtracted by 100%.

In this problem:

  • The initial value is of 1.2 mg.
  • The increase was of 1.8 mg - 1.2 mg = 0.6 mg.

Hence the percent increase is given by:

P = 0.6/1.2 x 100% = 50%.
