Answer:

t = 130s

Step-by-step explanation:

s = 3.9 * 10^{7} km

v = 3 * 10^{5} km/s

t = ?

t = \frac{s}{v}

t = \frac{3.9 * 10^{7} km}{3 * 10^{5}km/s }

t = 130 s

Given the equation 2(3x − 4) = 5x + 6, solve for the variable. Explain each step and justify your process.
blagie [28]
2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.

Solve (x - 5)2 = 3.
Deffense [45]

Answer:

x = 5±√3

Step-by-step explanation:

Equation: (x-5)² = 3

Step 1: Take the square root of both side of the equation

√(x-5)² = ±√3

x-5 = ±√3

Step 2: add 5 to both side of the equation

x-5+5 = 5±√3

x = 5±√3

Hence, from the options above, the right answer is

B. x = 5±√3
