Question

Consider this formula. z = y x If z = 4.0 and y = 8.4 , what is the value of x ? Express your answer to the tenths place (i.e., one digit after the decimal point). x =

Answer 1

Answer:

x=2.1

Step-by-step explanation:

$z=\frac{y}{x}$

we are given with values z = 4.0 and y = 8.4

Substitute the given values in the equation and solve for x

Plug in 4.0 for z  and 8.4 for y in the equation

$z=\frac{y}{x}$

$4.0=\frac{8.4}{x}$

multiply x on both sides

$4.0x=8.4$

divide both sides by 4.0

$x=\frac{8.4}{4.0}=2.1$

x=2.1
