x for 2 pointquestion y for 4 point question
x+y=40
2x+4y=100
x=40-y
80-2y+4y=100
2y=100-80
2y=20
y=10
x=40-10=30
Answer:
Give us the shaded region
Step-by-step explanation:
Answer:
C. 120
Step-by-step explanation:
area of trapezoid = (base1 + base2)h/2
area = (10 cm + 6 cm) * 15 cm/2
area = 16 cm * 15 cm / 2
area = (240 cm^2)/2
area = 120 cm^2
The answer is A. 50
2x + 40 = 140
2x = 140 - 40
2x = 100
x = (100 / 2 )
x = 50
