What is the value of x in the equation 2(x+3)=4(x-1) a.1 b.2 c.3 d.5

5

Step-by-step explanation:

2(x+3)=4(x-1)

2x+6=4x-4

6=4x-2x-4

6=2x-4

2x=6+4

2x=10

x=10/2

x=5

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
