10. Jack and Dion sold a total of 33 appliances for their store. Dion sold 3 less than twice as
many appliances as Jack sold. How many appliances did each person sell?
Equation
Jack sold
and Dion sold
appliances.

Let x = amount of appliances Jack sold

Let y = amount of appliances Dion sold.

We need to construct a system of equations to solve this problem

33 = x + y

y = 2x - 3.

Let's solve this system of equations by substitution.

33 = x + (2x - 3). Combine like terms.

33 = 3x - 3. Add 3 to both sides.

36 = 3x. Divide both sides by 3

12 = x. Plug this value into one of our original equations.

33 = 12 + y.  Subtract 12 from both sides

y = 21

Jack sold 12 appliances and Dion sold 21 appliances.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
