miskamm [114]
Let x= cucumber plants
5x= tomato plants
6x+7= pepper plants
peppers = 19 
therefore
6x+7=19
subtract 7 from both sides
6x= 12
 divide both sides by 6
x=2
replace the x with 2

2= cucumber plants
10= tomato plants

the sum of three consecutive even integers is 126. let x represent the least consecutive Integra. what is the greatest consecuti
madreJ [45]
First, we need to see how to get from one even integer to another. Well, what do you do to get from 2 to 4? 4 to 6? You add 2. If x is even, then the next even number must be x+2, and then the next x+4, and x+6, and so on. Since we're only going 3, we have:
x + (x+2) + (x+4) = 126. Now we can just solve the equation!

x + x + 2 + x + 4 = 126
3x + 6 = 126.
3x = 120.
x=40. But is that your answer? Nope! Don't forget, the problem says that <em>x is the smallest number out of the 3</em>. Which means 40 + 2 is the middle number, and 40 + 4 = 44 is the greatest.

Your answer is 44.

Let the original price be p.

Then the sale price was (1.00-0.18)p, or 0.82p.

Emerson must pay tax on this sale price.  It is 0.08(0.82p) = 0.0656p.

Thus, the final cost of the game was 0.82p + 0.0656p = 0.886p.
