Answer:
7.54 (.54 part repeats)
Step-by-step explanation:
Divide 83 by 11, because a fraction can be a division problem (fraction bar represents division)

System of Linear Equations entered :
[1] 3x - y = 19
[2] 8x - 5y = 20
Graphic Representation of the Equations :
y + 3x = 19 -5y + 8x = 20
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 3x - 19
// Plug this in for variable y in equation [2]
[2] 8x - 5•(3x-19) = 20
[2] -7x = -75
// Solve equation [2] for the variable x
[2] 7x = 75
[2] x = 75/7
// By now we know this much :
x = 75/7
y = 3x-19
// Use the x value to solve for y
y = 3(75/7)-19 = 92/7
Solution :
{x,y} = {75/7,92/7}
Answer:
5 miles.
Step-by-step explanation:
Because area is just length times width so in that sense 20/4 is 5 :)
Answer:
x = - 2, x = 12
Step-by-step explanation:
Given
x(x - 6) = 4(x + 6) ← distribute parenthesis on both sides
x² - 6x = 4x + 24 ← subtract 4x + 24 from both sides
x² - 10x - 24 = 0
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 12 and + 2, since
- 12 × 2 = - 24 and - 12 + 2 = - 10, thus
(x - 12)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 12 = 0 ⇒ x = 12
x + 2 = 0 ⇒ x = - 2
