Slove:33/29=46/x. Try to find the answer.

Tju [1.3M]

Answer:

$x=40\frac{14}{33}$

Step-by-step explanation:

we have

$\frac{33}{29}=\frac{46}{x}$

Solve for x

Multiply in cross

$(33)(x)=(46)(29)$

Divide by 33 both sides (Division Property of Equality)

$x=46(29)/33$

$x=\frac{1,334}{33}$

Convert to mixed number

$x=\frac{1,334}{33}=\frac{1,320}{33}+\frac{14}{33}=40\frac{14}{33}$
