Answer: 12<5x+4
Step-by-step explanation:
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
Step-by-step explanation:
Function is a process that associates to each element of a set X a one element of a set Y.

Answer:
Step-by-step explanation:
Ok, let's do this step by step....
Let's first simplify the x's:
Then we breakdown the 54 as 2 * 27 then simplify with the 10 above.
Now, we can rewrite this as the following and solve the bottom part:
The solution is
