Answer:

$x=-\frac{1}{5}$

Step-by-step explanation:

you combine like terms and set equal to zero you get $50x+10=0$ then subtract the 10 and divide by 50 it would give you a $-\frac{10}{50}$ which simplifies to be $-\frac{1}{5}$

If Sam buys 200 stickers at $10 and sells them for $.25 each how much is he making?

Alex17521 [72]

First you will need to multiple 200 by .25 to see how much money Sam will make.
200 x .25 = $50
now you need to subtract that price by 10 because he spent $10 to get the stickers.
50 - 10 = $40
Sam is making $40 off the stickers.
let me know if you have any other questions

The foul lines of a baseball field intersect at home plate to form a right angle. A batter hits a fair ball such that the path o

liraira [26]

Answer:

The angle formed between the first base foul line and the path of the baseball is 63°.

Step-by-step explanation:

This is not a difficult problem. We only need to remember the measure of a right angle, which is 90°. Now, recall that the path baseball divides the right angle in two angles, and we know the measure of one of them.

In the attached figure the black lines are the foul lines of the baseball field, and the blue line is the baseball path. In green is the given angles and colored red is the wanted angle.

So, the sum of the angles α and β is 90° and we know the measure of the angle α: 27°. So,

α + β = 90° .

Then,

β = 90° - α = 90° - 27° = 63°.
