25% off means the new price of the item is 75% of the originl price ( 100% - 25% = 75%)
Multiply the original price by 75%:
20 x 0.75 = 15
The sale price is £15
Answer:
C.)
Step-by-step explanation:
4x -20x -5b -x +2=-17x -8
-17x-5b+2=- 17x-8
+17x +17x
-5b +2= -8
-2 -2
-5b = -10
b= 2
hope this helps.
D=rt
c=speed of current
r=speed in still water
t=time
d=72
72=3(r+c)
72=4(r-c)
expand
divide top equation by 3 and bottom by 4
24=r+c
18=r-c
add them equations
42=2r+0c
42=2r
divide both sides by 2
21=r
sub back
18=r-c
18=21-c
minus 21 both sides
-3=-c
3=c
speed of current is 3
speed of ship is 21
