Answer:
4 months
Step-by-step explanation:
-Let the number of months it takes for their heights to equal be x and let h(x) be the height after x months.
#For plant 1, we equate height after x months as:
#For plant 2, we equate height after x months and at a constant rate m:
#we equate and solve for rate of growth, m in plant 2 as below:
#We then equate the two heights after x months to solve for x:
Hence, the plants have the same height after 4 months
Y is common to both top and bottom of the fraction so can be cancelled out ( because y / y = 1)
so the answer is 5/23

The answer is 30 cups
Let x be a multiplier. So:
2x + 5x + 9x = 96
16x = 96
x = 96/16
x = 6 cups
Since the number of onion cups is 5x, then 5 * 6 = 30 cups are needed to make 96 cups of salsa.
4 = y - 4
You need to add 4 on each side and you will get 8 which means that y is equal to 8.
4 = y - 4
+4 +4
8=y
