Answer:

let x be the number of roses  and y the number of daisies

x+y= 9 ( flowers)

3*x will be the cost of the roses

2*y will be the cost of daisies

then 3x+2y= 25 $ ( the cost of the 9 flowers)

therefore the 2 equations

x+y= 9

3*x+ 2*y= 25

solution of the two equations:

we multiply the 1st equation by 2

2x+ 2y= 18

3x+2*y= 25

2nd equation minus 1st equation  we will have:

x= 7 therefore y=2

Answer:

3r+2d=25

r+d=9

r=7 d=2

Step-by-step explanation:

use second equation and solve for d then

3r+2(9-r)=25

3r+18-2r=25

r=25-18

r=7

if r+d=9 and r=7 THEN d=2

Will bought 3 college textbooks. One cost 32$, one cost 45$, and one cost 39$. What is the average price of his book?
Damm [24]

Answer:

The average of all textbooks is $38.60.

Step-by-step explanation:

Here's why to calculate average we do sum of all numbers divided by the number of numbers, for example if we average 2 and 3, we do 2+3 divided by 2. Which happens to be 2.5. Now for this problem we divide the sum by 3.

Therefore getting our answer of $38.60.

92.96 as a fraction
nikklg [1K]
To change a decimal to a fraction you need to first place the decimal over 1. Next, for each number behind the decimal, you will multiply by a multiple of 10. Since there are 2 numbers behind the decimal, it's 100. Therefore, 
92.96 x 100 = 9296
1 x 100= 100


Your new fraction is 9296/100. Now we simplify it. I'm going by 2's so it may take a bit. 
Simplifying it twice by 2's your answer would be:

2324/25
