Dan ate brunch at a restaurant. The bill came to $87. If he left 15% tip, how much was the tip?

it would be 6xy and -16xy.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

here try this one

3a-24=0
