Step-by-step explanation:
How much is 84 out of 105 written as a percentage? Convert fraction (ratio) 84 / 105 Answer: 80%
Question 18
The answer is 4 days.
Because,
Kevin =3×n
Anita =4+ (2×n)
Equating the two equations.
3n=4+2n
3n-2n=4
n=4
Question 19
When the solution is (4,1), it means the value of y=1 and x=4.
The answer is;
y=x-3
y=-3x+13. Since when the values of x and y are substituted they satisfy the system.
Question 20
The system has no solution.
This is because the line are parallel and they do not intersect to give a solution.
C. grades in courses because it depends on how much the students study to get their grades
where is the question sir??
Answer:
a=8 b=6
Step-by-step explanation:
Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100
so a^2+b^2=100
8^2+6^2=100
64+36=100 ✔
and since A is longer than B, a=8, b=6
