Question

x varies directly as y and x= 15 when y= 12. Find x, when y is 4. pls solve I will mark you brainlliest​

Answer 1

Answer:

x = 5

Step-by-step explanation:

It is given that x is directly proportional to y

so if we remove the sign of proportionality we will get a constant. let the constant be 'k'

now, acc. to the question

x = ky

now put the initial values of both x and y

i.e. 15 = k × 12

k = 15/12

k = 5/4

now make another equation putting y = 4 and the value of k 5/4

so, it becomes

x = 5/4 × 4

x = 5
