There are 50 parking spaces because 10×5=50
Answer:

Step-by-step explanation:
We can use either angle, but I'm going to use the one on the bottom. So, in order to find x, we need to use tangent. One side we know is the adjacent, and the side we don't know is the opposite, therefore we need tangent. Here's the equation:

Obviously, we can't have a root in our denominator, so we need to get rid of it somehow. Here's how:
We multiply the denominator of the fraction by
.
multiplied by itself is simply 2. Try it! We also want to multiply the numerator by
, but there isn't really a number we can use with that, so we'll just add it to the side. The equation you have now is:

Let's try to work this out now. Since the denominator is 2, we have to multiply both sides by it to find x.


We can plug 2 in for the x in the numerator now:

2 and 2 cancel out, so you get 1 in both the numerator and denominator. That's how we get our answer of 
Also, because this is a 45-45-90 triangle, you don't really have to do all that work. If it's a 45-45-90 triangle, both legs should be the same length. :)
Answer:
the slope is -4/5 and the y-intercept is 0
Step-by-step explanation:
Answer:
D; x -y = 22
3x + 2y = 246
Step-by-step explanation:
Let us have the bigger number as x and the smaller as y
The difference between the two is 22
Thus, we have it that;
x - y = 22
twice the smaller number; 2(y) added to thrice the larger 3(x) equals 246
3x + 2y = 246
So we have the two equations as;
x -y = 22
3x + 2y = 246
Answer:
The answer is 3
Step-by-step explanation:
The answer is 3 because the number with x is always the slope.
