Answer:
Step-by-step explanation:
For problem 4, lets use Angles C and D as variables (so C and D)
33 + 6D = C
C + D = 180
Rearrange and solve.
33 + 6D = 180 - D
33 = 180 - 7D
-147 = -7D
D = 21 and C is = 159 (You can use your equations to check this.
For problem 5 let's think of small bowls as X and medium bowls as Y
x + y = 150 bowls
4x + 6y = 764 oz
solve with these equations and you find
4x + 6(150-x) =764
4x + 900 - 6x = 764
-2x = -136
x = 68, and you can plug that into x + y = 150 to solve for y which is 82
