Ok, let's settle this with a simultaneous equation...
0.25 * X + 0.10 * Y = 12.05
X + Y = 59
------
This means that:
X = 59 - Y
Which means that:
0.25 * (59 - Y) + 0.10 * Y = 12.05
0.25 * 59 - 0.25 * Y + 0.10 * Y = 12.05
Y (0.10 - 0.25) = 12.05 - 0.25 * 59
-0.15 * Y = -2.7
Y = (-2.7)/(-0.15)
Y = 18
---------
X + Y = 59
Therefore:
X + 18 = 59
X = 59 - 18
X = 41
-------------
There are 41 quarters and 18 dimes.
Answer:
0.786 Liters
Step-by-step explanation:
Rule:
1 mL = 0.001 L
So,
786 milliliters = 0.786 liters.
2/3 as many tables as chairs means 3/2 as many chairs as tables. So you can make the equation 4t-95=(3/2)t. Solving for t, the amount of tables, gets you 38 and there were originally 4 times that amount of chairs in the hall so there must have been 152 chairs at first.
Answer:
well it should be 20%
Step-by-step explanation:
80% of 100 is well, 80
