Answer:
5
Step-by-step explanation:
-x + 3y= 18
X= 3
-(-3)+3y =18
3 + 3y= 18
Subtract 3 from both sides.
3y = 15
Divide by 3 on both sides.
Y= 5
Answer:
108 feet²
Step-by-step explanation:
Well we can just multiply the corresponding sides of Quadrilateral ABCD to fit Quadrilateral EFGH.
Line EF is 42 feet
Line FG is 18 feet
Line GH is 18 feet
Line HE is 30 feet
The perimeter of Quadrilateral EFGH is
30+18+18+42=
30+36+42=
66+42=
108 feet²
Answer:
x = 125
Step-by-step explanation:
4 hrs : 200 mi
2.5 hrs : x mi
4/2.5 = 1.6 hrs
200/1.6 = 125 mi
x = 125 mi
72 + 74 is 146.
The angle sum of a triangle is 180.
180 - 146 is 34.
