Rate of change or slope. Hope it helps.
Answer:
AED and BEC
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
AEB + AED = 180.
AEB + BEC = 180.

1 car - 4 wheels
1 motorcycle - 2 wheels
x - number of cars
y - number of motorcycles
so, there are 70 vehicles: x + y = 70
and all togeather they've got 258 wheels: 4*x + 2*y = 258
because each car has 4 wheels, so all car wheels = 4*x,
likewise 2*y for motorcycles
x + y = 70 /* 4
4 x + 2y = 258
4 x + 4 y = 280 (R1)
4 x + 2y = 258 (R2)
2y = 22 /:2 it is R1 - R2
x = 70 - y
y = 11 /motorcycles
x = 70 - 11 = 59 /cars
check:
59 + 11 = 70 ok
59 * 4 + 11 * 2 = 236 + 22 = 258 ok
Answer:
60
Step-by-step explanation:
3 angles , so 180/3=60
Answer:
3022.08 . . . dollars per square meter
Step-by-step explanation:
The slope is multiplied by the factor that changes units:
(280.76 dollars/ft²)×(1 ft²)/(.092303 m²) ≈ 3022.08 dollars/m²
