In math
"is" means equals (=)
"of" means times (x)
x is 25% of 104
x = 25% x 104
x = .25 x 104
x = 26
He was 26 years old
THE SECOND ONE IS YOUR ANSWER!!
PLEASE GIVE BRAINLIEST!!
The ordered pair is a solution of x - y = 2 and 3y - x = 8 is (x, y) = (7, 5)
<h3><u>Solution:</u></h3>
Given two equations are:
x - y = 2 and 3y - x = 8
<em><u>To find: orderes pair i.e (x, y)</u></em>
Let us consider:
x - y = 2 ------- eqn 1
3y - x = 8 --------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "x" and "y"</u></em>
On rearranging eqn 2, we get
-x + 3y = 8 ------ eqn 3
Add eqn 1 and eqn 3
x - y = 2
-x + 3y = 8
(+) ---------------
0 + 2y = 10
2y = 10
<h3>y = 5</h3>
Therefore from eqn 1,
x - y = 2
x - 5 = 2
x = 5 + 2 = 7
<h3>x = 7</h3>
Thus the ordered pair to the given equations are (x, y) = (7, 5)
Answer:
Option B.
Step-by-step explanation:
There are 13 cards of club and 13 cards of spade in a standard deck of playing cards.
Total cards in a deck of playing cards = 52
The probability of choosing first card is club P₁ = 
The probability of choosing second card is spade = P₂ = 
Probability = P₁ × P₂
The probability of choosing one club and one spade is 
.
