Answer:
y = 2x
Step-by-step explanation:
Use Rise over Run. The rise(up/down) is 2 and the run(sideways) is 1. The slope is going up, not down so the 2 is positive. So, it is positive 2/1, which you can write as 2.
Answer: The speed of the current is 1.5 km/h .
Step-by-step explanation:
Let x = speed of current and y = speed of canoe.
Since ,
As per given , we have
Adding (1) and (2) , we get
Put value of y in (1) , we get
Hence, the speed of the current is 1.5 km/h .
(nx + py) / (x + y) = z, solve for p
nx + py = z(x + y)
py = z(x + y) - nx
py = zx + yz + nx
p = (zx + yz + nx) / y
Seems like the price goes up each year, so I'd say 7 years
Step-by-step explanation:
let total pizzas = y
so
32/100 x y = 64
y= 64× 100/32
= 200 pizzas
