How to do this with steps ??

Are 9, x,x,49 in proportion??

Answer 1

Solve numeric proportions such as 4/5 = 20/x. Identify the variable, in this case as “x.”

Cross-multiply by multiplying the numerator in the first fraction by the denominator in the second fraction and the denominator in the first fraction by the numerator in the second fraction.

Set up a new equation. Place the number you multiplied with the variable directly next to the variable, followed by an equal sign. Write the product of the other numbers on the right side of the equal sign. For example, in 4/5 = 20/x, the new equation becomes 4x = 100 after cross-multiplication.

Answer 2

SOLUTION;
9:x::x:49

or,9/x=x/49

or,x^2=49*9

or,x^2=441

or,x= √441=21

so x is 21 ans.
