Answer:
y = 5/9x - 37/3
Step-by-step explanation:
5x - 9y = 8
-9y = -5x + 8
y = 5/9x - 8/9
- When a line is parallel, the slope remains the same.
y = 5/9x + b
-9 = 5/9(6) + b
-9 = 10/3 + b
-37/3 = b

let AB = E
⇒ (AB) (7 m) = (1.75 m) ( BC + AB)
(AB) (7 m) = (1.75 m) (1.5 m + AB)
= 2.625 m² + (1.75 m ) (AB)
(AB) (7 m - 1.75 m) = 2.625 m²
∴ AB = 2.625 m² ÷ (5.25 m)

⇒ the length of AB is 0.5 m</span>
Answer:
Step-by-step explanation:
10/4=2.5
8/2.5=3.2
3.2 hours
Its the second one. With (1+0.3)25 multiply 25 by 1 and then multiply 25 by 0.3 and add both answers. With 25+0.3(25) you still multiply 25 by 0.3 and you add 25.
