6) Solve for x. 2/3 (x + 7) = 10 A)22 B)8 C)- 1 /3 D)41/ 3

Amiraneli [1.4K]

For this case we must find the value of the variable "x" of the following equation:

$\frac {2} {3} (x + 7) = 10$

We multiply by 3 on both sides of the equation:

$2 (x + 7) = 30$

We divide between 2 on both sides of the equation:

$(x + 7) = 15\\x + 7 = 15$

We subtract 7 on both sides of the equation:

$x = 8$

Solve by using Pythagorean Theorem, a= 5, b= x-1, and c=x

charle [14.2K]

The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.

Step-by-step explanation:

The given is,

a = 5

b = x - 1

c = x

Step:1

Pythagorean theorem is,

$a^{2} + b^{2} = c^{2}$ ................................(1)

( It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides )

From the given values the equation (1) becomes,

$5^{2} + (x-1) ^{2} = x^{2}$

( $(a-b)^{2} = a^{2} + b^{2} -2ab$ )

25 + ( $x^{2}$ + 1 - 2x ) = $x^{2}$

25 + 1 -2x = 0 ( ∵ Eliminate $x^{2}$ in both sides)

26 = 2x

x = 13

Step:2

From the values of x,

a = 5

b = ( 13 - 1 ) = 12

c = 13

Result:

The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
