Answer:
1
Step-by-step explanation:
To answer the question, divide the amount of fiber taken during breakfast by the total allowable amount then multiply by 100%. This gives us,
(66 / 25) x 100% = 264 %
Thus, the answer is 264%. The answer clearly shows that the fiber taken so far is much more than the total allowable fiber intake.
eq^2: 7x=84 divide 84 by 7 which is 12.
therefore x is equal to 12. Then
1) take that 12 you got in equation 2 and substitute in equation 1 which is:
7x-12y=180
7(12)-12y=180
84 -12y=180
-12y=180-84
-12y=96 ............divide both sides with -12
-y=8 (×-1) both sides
y= -8
therefore 7(12)-12(-8)=180
see how it do it in the picture and hope it helps you..
Answer: 40 students.
Step-by-step explanation:
To solve this problem you mmust apply the steps shown below:
1. You know that there is a total of 100 students, then you can say that the 100% is 100 students.
2. Then, to calculate how much would 40% be, you must multiply 100 students by 40% which you rewrite as a decimal by dividing it by 100, as following:
40%/100=0.4
Then 40% of the students would be
100 studens*0.4=40 students
