5/6 because she already picked a blue tile. it makes the grey tile to be picked.
X= -2/5 + y/5 solve for x by simplying both sides of the equation, then isolating the variable
Answer:
I = V/R
Step-by-step explanation:
V = IR
Divide by R on both the sides,
I = V/R
12 more than 8.2 times a number n is the same as “8.2n + 12”.
Answer:
The answer to your question is k = -3233
Step-by-step explanation:
Data
x₁, x₂ are the roots
Equation l x² - 8x + k = 0
Equation ll 3x₁ + 4x₂ = 29
k = ?
Process
1.- Write another equation
x₁ + x₂ = - 8
2.- Solve the system of equations by elimination
3x₁ + 4x₂ = 29 Equation l
x₁ + x₂ = -8 Equation ll
-Multiply equation ll by -3
3x₁ + 4x₂ = 29
-3x₁ - 3x₂ = 24
0 + x₂ = 53
-Find x₁
x₁ + 53 = -8
x₁ = -8 - 53
x₁ = -61
2.- Find k
(x₁)(x₂) = k
(53)(-61) = k
k = -3233
