A) 30 pages
Step-by-step explanation:
No of pages = 75
Aman coloured 60 % of the pages= 75 *60/100= 45
Prakash coloured 75 - 45 = 30 pages
Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
Answer:
It has to be 25 it is the middle number
Hello!
Let's put this as a system of equations.
r= 8+g
r+g=14
Let's plug our r value into the second equation and solve for g.
8+g+g=14
8+2g=14
Now we subtract 8 from both sides.
2g=6
We divide both sides by 2.
g=3
Therefore, he has 3 green peppers.
I hope this helps!
Answer:
Step-by-step explanation:
The expression is
x^2 - 4
This is a quadratic expression.
To find the solution, we will equate the the expression to zero. It becomes
x^2 - 4 = 0
Add 4 to the left hand side of the equation and the right hand side of the equation. It becomes.
x^2 - 4 + 4 = 0 + 4
x^2 = 4
Take square root of the right hand side of the equation and left hand side of the equation. It becomes
√x^2 = √4
x = ± 2
x = 2 or x = - 2
