6. x = 16; it's a scalene triangle
7. x = 45; it's a right triangle.
Answer:
6 pieces
Step-by-step explanation:
4/4 - 1/4 = 3/4
(3/4) / (1/8) = (3/4) * (8/1) = 24/4 = 6
30 ft = 5mi
X mi = 45.5mi. (Cross multiply)
5x= 45.5•30
5x= 1365
X= 1365/5
X= 273
Map: 273 ft
Answer:
(1,40) equation: y=40x
(2,50) equation: y=25x
(4,70) equation: y=17.5x
(7,80) equation: y=11.43x
does not represent a proportional relationship because they all have different equations.
