Answer:
2/5 of iron
Step-by-step explanation:
∵ 3/4 cup of oatmeal contains 1/10 of iron.
∴ 1 cup of oatmeal will contain
=2/5 of iron
Solve the following system:
{3 x - 5 y = 7 | (equation 1)
{10 y - 4 x = 16 | (equation 2)
Swap equation 1 with equation 2:
{-(4 x) + 10 y = 16 | (equation 1)
{3 x - 5 y = 7 | (equation 2)
Add 3/4 × (equation 1) to equation 2:
{-(4 x) + 10 y = 16 | (equation 1)
{0 x+(5 y)/2 = 19 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + 5 y = 8 | (equation 1)
{0 x+(5 y)/2 = 19 | (equation 2)
Multiply equation 2 by 2:
{-(2 x) + 5 y = 8 | (equation 1)
{0 x+5 y = 38 | (equation 2)
Divide equation 2 by 5:
{-(2 x) + 5 y = 8 | (equation 1)
{0 x+y = 38/5 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{-(2 x)+0 y = -30 | (equation 1)
{0 x+y = 38/5 | (equation 2)
Divide equation 1 by -2:
{x+0 y = 15 | (equation 1)
{0 x+y = 38/5 | (equation 2)
Collect results:
Answer: {x = 15
{y = 38/5 or 7.6 decimal
I believe its 838 inches squared
Hello!
First you have to find the area of the floor
To do this you multiply the sides
4 * 4 = 16
Next you find the area of the rug which is a circle
The equation for this is A =

r is radius
Put in the values you know

A = 7.07
Subtract this by the area of the floor
16 - 7.07 = 8.93
The answer is 8.93m squared
Hope this helps!
