Which value of x satisfies the equation 1/2 (x+ 5/2)= 15/4?

x = 5

Step-by-step explanation:

Given

(x + ) =

Multiply both sides by 4 to clear the fractions

2(x + ) = 15 ← distribute parenthesis on left side

2x + 5 = 15 ( subtract 5 from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

x = 5

Step-by-step explanation:

i solved x using trial and error

1/2 (x+ 5/2)= 15/4

so i tried with 2

1/2 (2 + 5/2)= 9/4

which is too less, so i tried with 7

1/2 (7+ 5/2)= 19/4

which is too big, so i tried with 6

1/2 (6+ 5/2)= 17/4

which is nearly there and i tried with 5

1/2 (5+ 5/2)= 15/4

and it came exactly

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

the answer is 13 cm
