Answer:
127.2 litres
Step-by-step explanation:
Let x be the number of 80% strawberry juice( in litres ) mixed with 6 litre of 20% strawberry juice mixture to obtain 55% strawberry juice,
∵ Resultant mixture = (6+x) litres,
Since, strawberry in x litres + strawberry in 6 litres = strawberry in resultant mixture
⇒ 80% of x + 20% of 6 = 55% of (60+x)
⇒ 80x + 20 × 6 = 55(60+x)
⇒ 80x + 120 = 55 × 60 + 55x
⇒ 80x = 3300 + 55x - 120
⇒ 80x - 55x = 3180
⇒ 25x = 3180
⇒ x = = 127.2
Hence, 127.2 litres of 80% mixture should be mixed.
Answer:
x =20
Step-by-step explanation:
6% of x = 1.2
Change percent to decimal form
.06x = 1.2
Divide each side by .06
.06x / .06 = 1.2/.06
x =20
Answer:
The value of y by itself in the equation x+2y=10 is
Step-by-step explanation:
Given equation is x+2y=10 -------- (1)
To find y with given equation as below :
Equation (1) implies that x+2y=10
Subtracting the above equation by x we get
x+2y-x=10-x
x-x+2y=10-x
2y=10-x
Dividing by 2 on both sides we get
Therefore the value of y is
Therefore the value of y by itself in the equation x+2y=10 is
