a- y=8
b- y=-94
c- y=28
d- y=27
Step-by-step explanation:
multiply the denominator with the mixed number then add the numenator
4 × 2 +1 /4
= 8 + 1/4
= 9/4
again for mixed fraction
divide the numenator by denominator and put the quotient in the front side and remaining in numenator
13/7
= quotient = 1 , remaining = 6
4.5x+7.05y=$43.65
x+y=8
Timed 4.5 for both side to get
4.5x+4.5y=36
4.5x+7.05y=43.65
-
4.5x+4.5y=36
=
2.55y=7.65
y=3 pounds
x=5 pounds. Hope it help!
Answer:
<h2>
2.4 Litres of water</h2>
Step-by-step explanation:
80% of (3 litres)
You can take 3 litres to be 3000 ml which is how I solved it.
<h2>
OPTION 1</h2><h2>
_________</h2>
80/100 x 3000
=2400 or 2.4 litres
The same can go with not taking ml which you can just use litres
<h2>
OPTION 2</h2><h2>
_________</h2>
80/100 x 3
=2.4 litres
I used the ml since I do not need the calculator for that one and it is faster to calculate.
