Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!
Answer:
Equation: 10x-12=6x-6
X: 3/2 or .5
Perimeter of square and triangle are both 3.
Step-by-step explanation:
Square:
4(2.5x-3) {The four represents the amount of sides}=
10x-12
Triangle:
3(2x-2)=
6x-6
Since they have the same perimeter the equation is
10x-12=6x-6
10x-6x=12-6
4x=6
x=1.5
Square pt 2:
4(2.5(3/2)-3)=
4(3.75-3)=
4(0.75)=
3
Triangle pt 2:
3(2(3/2)-2)=
3(3-2)=
3(1)=
3
Number of ways the second grade students can sit on the first row is 5! = 5P5
Number of ways 15 first grade students can sit in the remaining 20 seats is 20P15
Therefore, required number of ways is 5P5 * 20P15. (option B)
