Answer:
5% of his coins is 7
Step-by-step explanation:
140 X 0.05 = 7
The ratio 2 to 5 means there are 2 cats and 5 dogs but the 5 to 2 ratio means there are 5 cats and 2 dogs.
Any of the 11 man can be chosen, and combined with any of the 8 women.
Assume we select man1. The selected committee can be:
(m1,w1), (m1,w2), (m1,w3), (m1,w4), (m1,w5), (m1,w6), (m1,w7), (m1,w8),
so there are 8 committees selections with man1 in them.
we could repeat the same procedure for the remaining 10 men, and get 8 committees where each of them is a member.
so there are 11*8=88 ways of choosing 1 man and 1 woman.
Answer: 88
2x*2 + 6x + 80
First we have to use distribution property
2(x*2 + 3x + 40)=0
Divide 2 to both sides
X*2 + 3x + 40=0
Multiply -1
-x*2 -3x-40=0
Add two numbers to get 3x
Multiply same two numbers that you add to get 40x*2
Add
-8x+5x= -3x
Multiply
-8x . 5x= -40x*2
-x*2-8x+5x-40
(X*2-8x) + (5x-40)
X(x-8)+ 5(X-8)
Common factor
(X-8)(x+5)
This would help you!
