The first step to solving this is to collect the like terms in this equation,, which are all the numbers with an x variable attached to them.
8.5x = -25.5
Now all you need to do to find x is divide both sides of the equation by 8.5
x = -3
This means that in order to make this equation true,, x must be -3.

John has a job selling souvenirs on a football stadium. He earns $10 per game plus $0.25 dollars for each souvenir he sells. How
Ahat [919]

Answer:

He needs to sell 100 souvenirs

Step-by-step explanation:

We want to know the number of souveniers John has to sell

Let the number of souveniers he sold at the game be s

At a rate of $0.25 per souvenier, the amount earned on souveniers for s souveniers will be:

0.25 \times s =0.25s

Now, if we added this to the amount he earns per game, we will have the total $35 earned for working at one game.

Thus, mathematically:

0.25s + 10 = 35 \\ 0.25s = 35 - 10 \\ 0.25s = 25 \\ s =  \frac{25}{0.25}  \\ s = 100

a swimming pool 25m by 10m has a concrete border all round. Find the area of the concrete border if it is 2.5m wide at the sides
Ksju [112]
So from what I understand, you would multiply 10m by 5m for the width to get 50m squared, and multiply the 50 by 2 to get 100m for both sides of the width for the pool. Next the length. Multiply 25m by 2.5m to get 62.5m squared. Once again, mutiply it by 2 for both side lengths of the pool to get 125m. Last, add 125m and 100m to get 225m for the concrete border of the pool.
