In order to solve this equation, let's write it out in number form:

-3 - x = -10

In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the -3 by adding 3 to both sides:
-3 + 3 - x = -10 +3
-x = -7

Because there are negatives on both sides, you can simply cancel them out:

x = 7

A cooler contains 4.5 gallons of water and is filling up at a rate of 0.1 gallons per second. A second cooler contains 7 gallons

denpristay [2]

The equation that can be used to determine when each cooler would contain the same amount of water is 4.5 + 0.1t = 7 + 0.25t

<h3>When the coolers would have the same amount of water?</h3>

Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t

Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t

Where t represents seconds

When they have the same amount of water, the two above equations would be equal

4.5 + 0.1t = 7 + 0.25t

Combine similar terms

7 - 4.5 = 0.1t - 0.25t

2.5 = 0.75t

Hence the equation that can be used to determine when each cooler would contain the same amount of water is 4.5 + 0.1t = 7 + 0.25t

The Band Booster club sells beverages for $1.26 and candy for $1.09 at home games. Their goal is to have total sales of $181.59

natima [27]

Amount times cost=profit

profit beverages=x times 1.26 or 1.26x
profit candy=y times 1.09 or 1.09y

the total profit is profit beverage plus profit candy or 1.26x+1.09y
they want total profit of 181.59

so
181.59=1.26x+1.09y is the answer in standard form
usually, we want whole numbers, but that's fine
