Question

A number g is decreased by 23 and then
multiplied by 1/2 The result is 8 more than
twice the number g.

Answer 1

A. -13

The equation would be

(G-23)1/2=2g+8

Multiply by 2 on both sides to get rid of the fraction

G-23=4g+16

subtract g from both sides

-23=3g+16

Subtract 16 from both sides

-39=3g

Divide 3 from both sides

g=-13

Answer 2

A number g is decreased by 23 and then multiplied by 1/2 The result is 8 more than twice the number g. Then the value of g is -13.

How to estimate the value of g?

From the given information the equation would be

$\frac{(g-23) \cdot 1}{2}=2 g+8$

Multiply both sides by 2

$\frac{(g-23) \cdot 1}{2} \cdot 2=2 g \cdot 2+8 \cdot 2$

Simplifying the above value, we get

g-23 = 4g+16

Add 23 to both sides, we get

g - 23 + 23 = 4g + 16 + 23

Simplify

g = 4g + 39

Subtract 4g from both sides

g - 4g = 4g + 39 - 4g

Simplify

-3g = 39

Divide both sides by -3

$\frac{-3 g}{-3}=\frac{39}{-3}$

Simplifying the above equation, we get

g = -13

Therefore, the correct answer is option A) -13.
