Suppose that y varies directly with x and inversely with z and y = 28 when x = 32 and z = 8. write the quation that models the r

WITCHER [35]

Given that y varies directly with x and inversely with z, then:
a] Equation that models the relationship
y=kx/z
where k is the constant of proportionality, given by:
k=yz/x
k=(28×8)/32
k=7
The equation that models the relationship is:
y=7x/z

b]
find y when x = 12 and z = 3
The value of y will be given:
y=(7×12)/3
y=28

The product of a number and -2/3 is -9/10 (20 Points) What is the number?

poizon [28]

Answer:

$\large\boxed{n=\dfrac{27}{20}}$

Step-by-step explanation:

$\text{Let}\ n\ \text{is a number.}\\\\\text{The product of a number and}\ -\dfrac{2}{3}\ \text{is}\ -\dfrac{9}{10}:\\\\-\dfrac{2}{3}\cdot n=-\dfrac{9}{10}\\\\-\dfrac{2n}{3}=-\dfrac{9}{10}\qquad\text{change the signs}\\\\\dfrac{2n}{3}=\dfrac{9}{10}\qquad\text{cross multiply}\\\\(2n)(10)=(3)(9)\\\\20n=27\qquad\text{divide both sides by 20}\\\\\dfrac{20n}{20}=\dfrac{27}{20}\\\\\boxed{n=\dfrac{27}{20}}$
