Answer:
"Decrease of 60 dollars"
Step-by-step explanation:
<u>Sales</u>
Monday = 2000
Tuesday = 10% less = 2000*0.9 = 1800
Wednesday = 20% less = 1800 (0.8) = 1440
Thursday =
25% of Monday = 25% * 2000 = 500
Sales increased by 500 on Thursday compared to Wednesday. So Sales were:
1440 + 500 = 1940
So, compared to Monday (2000) , thursday's sales was $60 less
I think is 5/20 and then simplify
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63

Answer:
4900 Litres
Step-by-step explanation:
First we need a common demoninator:
3/7=15/35
Then we subtract the two to figure out how much 420 Litres is:
15/35-12/35=3/35
3/35=420 litres
Divide amount by the numerater for thow much 1/x is.
1/35=140
and multiply by the denomenator to get a full number on your fraction, and therefore a full tank.
140 x 35 = 4900
