Find two consecutive even integers such that twice the second is the same as 186 less than the first integer.​
Alisiya [41]

Step-by-step explanation:

let the 2 integers be x and x + 1

2(x + 1) + 186 = x

2x + 188 = x

x = -188

therefore the 2 integers are -188 and -187

9 - 1.8 = 7.2

The sale price of the DVD is $7.20.

Your school is selling granola bars for a fundraiser. They purchased 1250 granola bars and paid a delivery fee of $25. The total
MariettaO [177]
Hello!

First we have to define a variable.

Let x stand for the price of a granola bar

Then we have to make our equation

1250x + 25 = 800

This is the equation because the price for all the granola bars and delivery was $800

Now we solve it

Subtract 25 from both sides

1250x = 775

divide 1250 from both sides

x = 0.62

The cost for a granola bar is $0.62 or 62 cents

Hope this helps!
