Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.
hope it helps u
To solve for x, the first thing to do is to distribute the 4 to (x-2). When you do this, you should get 4x-8=4x+10
Then, subtract 4x from both sides and then you are left with -8=10. Because -8 is not equal to 10, meaning the equation you are left with is not a true statement, the answer to this would be that there are no real solutions.
Answer:
Function: C = 500 / n
Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.
Step-by-step explanation:
1. Cost per share, C, with respect to the number of contributors, n is
C = 500 / n
So, with 5 contributors, the price is $100 per share. $100 = 500/5
2. C= $20
20= 500 / n
20 * n = 500 * n
20n = 500
n= 25
She already has 5 contributors, so she needs 20 more.
=10(4+13x-5)
=10(-1+13x)
=-10(13x)
=-130x
You would divide negative 3 (-3) from both sides to keep the c by itself. When you divide a positive by a negative it becomes negative.
Dividing 15 by -3 would equal -5, so c = -5
