Answer:
6.66 liters
Step-by-step explanation:
34% of one liter would leave 66% of the liter left, and if you were to add the other 6 liters to it, you would get your answer.
Answer:
c = 34
Step-by-step explanation:
x²+19x+c=0
(x + a) (x + b) = x² + (a + b) x + ab
a + b = 19
a - b = 15
a = 17
b = 2
c = ab = 34
Answer: cup is $2.55
Saucer $0.55
Step-by-step explanation:
Cost of cup and saucer is $3.10
Let the cup be x
And saucer be y
I.e
X+y= 3.10......equation 1
Cup which is X is $2 more than the saucer
I.e x=2+y......equation 2
Substitute for X in equation 1
(2+y)+y=3.10
2+2y=3.10
2y=3.10-2
2y=1.10
Y=1.10/2
Y=$0.55
Substitute for y in equation 2
X=2+y
X=2+0.55
X=$2.55
Therefore
The cup is $2.55
The saucer is $0.55
