Hello!

First, set a variable for "spending $2 each day". This is important as the number of days passed is not set, and it varies, so we need a variable for it. Say d = number of days passed.

Now, write out the equation. The first thing we want to write is "You had $150". This can be represented by just writing out the number 150.

Our equation now: 150

Finally, add the variable. This would be "you are spending $2 each day". For this, you must subtract 2 times d from 150.

Our final equation: 150 - 2d

Hope this helps!

as a fraction of 180, m < 1 = 1/ (1 + 3 + 2) * 180 = 1/6  * 180  = 30 degrees

m < 2 = 3*30 = 90 degrees

and m < 3 = 30*2 = 60 degrees

anygoal [31]

Answer:

Sqrt of 160

Step-by-step explanation:

The distance, try to think it as a triangle, so you will find out that the distance equals the sqrt of(8-(-4))^2 + (9-5)^2, so it will be sqrt of(144+16) which is sqrt of 160, so the answer will be sqrt of 160
