Answer:
$8.75 left
Step-by-step explanation:
30 - 5^2 x
= 30 - 25 x
if x = 0.85 then
30 - 25 (0.85)
= 30 - 21.25
= 8.75
She has $8.75 left
L=W-2LW=35 substitute in W-2 for L(W-2)(W)=35W2 -2w -35=0(W-5)(W-7)=0therefore w=7 and L=5
Answer:

Step-by-step explanation:
velocity of river with respect to ground = 4 mi/h south

Velocity of swimmer with respect to river = 2 mi/h east

According to the formula of relative velocity


Where, V(S,G) be the velocity of swimmer with respect to ground, it is true velocity of swimmer.
