Given Equations :
✿ 2x + y = 20 ------------------ [1]
✿ 6x - 5y = 12 ----------------- [2]
Multiplying Equation [1] with 5, We get :
⇒ 5(2x + y) = 5(20)
⇒ 10x + 5y = 100 -------------- [3]
Adding Equations [2] and [3], We get :
⇒ (10x + 5y) + (6x - 5y) = 100 + 12
⇒ 16x = 112
⇒ x = 7
Substituting x = 7 in Equation [1], We get :
⇒ 2(7) + y = 20
⇒ 14 + y = 20
⇒ y = 20 - 14
⇒ y = 7
So, The Solution for the Given System of Equations is : (x , y) = (7 , 7)
Answer:
Step-by-step explanation:
Probability of winning a game = 0.34
a) Probability of winning two games simultaneously = .34 x .34 =.1156
b) Probability of winning 3 games in a row = .34³
c) Probability of winning three chess games in a row and failure in the fourth = .34³ x ( 1-.34)
c)
Answer:
The scale factor is 4/3 or 1.333...
Step-by-step explanation:
We're trying to find how can A go to B
Example: 16 --> 12
16 Divided by 12 = 4/3
÷
This will work with other numbers too.
