Karla can buy guppies for $0.90 each at the corner pet store. If she has $13.50, how many guppies can she buy? 
pshichka [43]

All we have to do here is divide $13.50 by $0.90 to figure out how many guppies she can buy

$13.50 ÷ $0.90 = 15

Therefore, Karla can buy <u>15 guppies</u> with $13.50

Hope this helps you

Brainliest would be appreciated

The midpoint of a segment is (−6,−5) and one endpoint is (1,3). Find the coordinates of the other endpoint.
Evgen [1.6K]
C. (-13,-13)
You take the x of the midpoint and equal it to the formula of the midpoint so it will be -6 = 1+x/2 so 1st you times 2 by 6 because you wanna get rid of 2 so it will -12 Then when you move 1 so x is alone it will be -1 so -12-1= -13
Same thing for y
