Lane is 10 times Mels age. If the difference in their age is 27, how old is Mel?
Answers
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
27 = L - M
27 = 10M - M
27 = 9M
M = 3
L = 10M = 10(3) = 30
Lane is 30 years old
Mel is 3 years old

Answer: 39 and 83
Step-by-step explanation:
Let's assume the smaller number is represented by 'x' and the larger number is represented by 'y'.
According to the given information, we have two equations:
Equation 1: x + y = 122
Equation 2: 3x - 34 = y
We can solve this system of equations to find the values of 'x' and 'y'.
Substituting Equation 2 into Equation 1, we get:
x + (3x - 34) = 122
Combining like terms:
4x - 34 = 122
Adding 34 to both sides:
4x = 122 + 34
4x = 156
Dividing both sides by 4:
x = 39
Substituting the value of 'x' back into Equation 1:
39 + y = 122
Subtracting 39 from both sides:
y = 122 - 39
y = 83
Therefore, the smaller number is 39 and the larger number is 83.

i... There are 13 spade cards and then 3 other aces since there are 4 suits of cards so 16/52 or about 0.30769 or 30.8% rounded
ii....There are 2 reds of each card in a standard deck along with 2 blacks so there would be 2 red kings which would be a 2/52 chance or about 0.0384 or 3.8% rounded
iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded
iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded

If so, multiply using FOIL:
First: wx * wx = w^2x^2
Outside: wx * -y^2 = -wxy^2
Inside: -y * wx = -wxy^2
Last: -y^2 * -y^2 = y^4
Combine w^2x^2 - 2wxy^2 + y^4
Answer:
