I JUST NEED POINTS
30 times .4=12
30-12=18
The sales price would be $18
Answer:
112
Step-by-step explanation:
use substitution method:
make 2 equations:
44 = 2(l+w) l=w+6
plug in l:
44 = 2 (w+6+w)
combine like terms:
44 = 2(2w+6)
distribute:
44 = 4w + 12
get 4w alone:
44 = 4w + 12
-12 -12
__________
32 = 4w
Divide to get w alone :
32 = 4w
__ __
4 4
w=8
plug w in:
l = w + 6
l = 8 + 6
get l alone on one side:
l = 14
plug l and w in an are equation:
14 x 8 = 112
Answer:
40 L
Step-by-step explanation:
20% empty is the same as 80%full
.8f = .2f + 24
subtract .2f from both sides
.6f = 24
divide both sides by .6
f = 40
