The area is the same, regardless of how you find it. It is the product of base length and height measured perpendicular to that base.
.. 15*8 = 10*AX
.. AX = 15*8/10 = 12

3/3 would be your answer in exact form.
7% of 350 is 24.5. So the answer is $374.5
Answer:
40-9x+4x+5=
45-5x
You can't do anything else because the variables are different.
the number of cups of red Lin needs is 27 cups
Explanation:number of parts of red = 3
number of parts of yellow = 2
the ratio of red to yellow = 3:2
when lin's number of cups of yellow = 18
let the number of cups of red = x
3 red = 2 yellow
x red = 18 yellow
cross multiply:
3(18) = 2(x)
54 = 2x
divide both sides by 2:
54/2 = 2x/2
x = 27
Hence, the number of cups of red Lin needs is 27 cups
