Answer:
is the median for both of them .
Step-by-step explanation:
Answer: Mark has 28 marbles while Don has 85 marbles.
Step-by-step explanation:
Let x represent the number of marbles that Mark has.
Let y represent the number of marbles that Don has.
If Don has 1 more than 3 times the number of marbles Mark has, it means that
y = 3x + 1
The total number of marbles is 113. It means that
x + y = 113- - - - - - - - - - - - 1
Substituting y = 3x + 1 into equation 1, it becomes
x + 3x + 1 = 113
4x + 1 = 113
4x = 113 - 1 = 112
x = 112/4
x = 28
y = 3x + 1 = 3 × 28 + 1
y = 85
Answer:
It has 2 solutions
Step-by-step explanation:
Solution 1
-17(y - 2) = -17y + 64 - 17(y - 2)
Solution 2
-17y + 64 - 17(y - 2) = -17y + 64
To calculate for mass, simply multiply molar weight (MW)
and number of mols. The molar weight (MW) is in units of mg / mmol. Therefore
the mass is:
mass = (158 mg / mmol) (0.25 mmol)
mass = 39.5 mg
Answer:
39.5
Answer:
14 meters ^2
Step-by-step explanation:
formula: A=(h<em>b*</em>b)/2
A=(4*7)/2
A=(28)/2
A=14
