Answer:
x>-1
Step-by-step explanation:
for plates she can buy 3 and for cups she can buy 2
both multiply up to 24
x=70
when added together, verticle angles equal 180 degrees.
2x-10+x+20=180
3x-10+20=180
3x-30=180
3x=210
4y^2 + 2 - 2 = 38 - 2 (subtract both side by 2)
4y^2 = 36
Divide by 4:
y^2 = 9
y =
y = 3
