Write two word problems that can be solved usingthe equation x + 15 = –18.

Word Problem #1:

You are in a submarine at a depth of some unknown value x. The submarine rises 15 feet. After this point, you are able to record the depth to be 18 feet below sea level.

x = original depth

15 = height you rise up

-18 = final depth

x+15 = final depth

x+15 = -18 is the equation we solve to find the value of x

Word Problem #2:

You are in debt to your friend. Debt is represented by negative numbers. For example, writing -2 means you are 2 dollars in debt. If you start off being x dollars in debt, but pay off $15, then you will have a balance of x+15 dollars. If this new final balance is -18, then we can say x+15 = -18

So in short: you go from x dollars in debt to 18 dollars in debt after paying off $15 to your friend.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
