The value of y is 18.46 when x=10 and z = 26
Step-by-step explanation:
The direct proportion is denoted as:
y∝x
And the inverse proportion will be denoted as:
y∝1/z
combining both
y∝ x/z
When the symbol of proportionality is removed, the proportionality constant is introduced

Given
y = 32 when x=4 and z = 6
Putting the values

So the equation will become:

Putting x=10 and z= 26

Hence,
The value of y is 18.46 when x=10 and z = 26

Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.
