Ok, for this one...  see the picture

Step 1:  Find angle R by adding angle Q and P then subtract from 180 (all angles add to 180).  That gives us R angle of 70 degrees.

Step 2:  Find angle QRX by subtracting angle R from 180 (the 2 angles that make up the straight line will add to 180).  180 - 70 = 110 degrees.

Step 3:  Find y by setting the equation to the answer we found in step 2.
y + 25 = 110
y = 85 degrees

Check out the picture.  It should help.

Five friends split a $65.20 bill at a restaurant . They also each left $2.75 for the tip. How much money did each person pay in
kvv77 [185]
You start by doing 65.20 (the bill) divided by 5 (the amount of people paying)
65.20 / 5 = 13.04 

Then you add 13.04 (how much each person paid towards the bill) and 2.75 (the amount of money each person left as a tip) 
13.04 + 2.75 = 15.79

Each person paid $15.79

Sam is planting a garden that measures
nikitadnepr [17]

Answer:

63.7 feet

Step-by-step explanation:

We can re-write the width and the length both as rational numbers:

- Width: w=6.5=\frac{65}{10}

- Length: L=9.8=\frac{98}{10}

So now we can find the area of the garden by multiplying width and length:

A=wL=\frac{65}{10}\cdot \frac{98}{10}=\frac{65\cdot 98}{10\cdot 10}=\frac{6370}{100}=63.7
