Two customers went to a flower shop to buy roses and daisies. Each bunch of roses costs the same amount, and each bunch of daisies costs the same amount. The first customer paid $62.00 for 3 bunches of roses and 4 bunches of daisies.
The second customer paid $60.00 for 2 bunches of roses and 5 bunches of daisies.
What was the cost, in dollars, of each bunch of roses?

(A) $8.25

(B) $9.50

(C) $10.00

(D) $12.00

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
