Question

Use cross products to solve the proportion.
14/21=a/9

Answer 1

Answer:

$\sf\boxed{a=6}}}$

Step-by-step explanation:

Isolate the term of a from one side of the equation.

14/21=a/9

Use cross products.

$\sf{14*9=21*a}$

Solve by a.

$A=\dfrac{14*9}{21}=\dfrac{126}{21}=\boxed{\sf{6}}$

a=6

So, the final answer is a=6.
