Ryan’s backyard is filled up ¼ with snow, he’s expecting another ½ of snow to come. In the meantime, Ryan uses his shovel to shovel away ⅛ of the snow in his backyard. How much snow is left in his backyard? How much snow will be left in his backyard if the snowstorm hits?

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

$12. that is my answer.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
