Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4
Step-by-step explanation:
Answer:
2, 3, 6
Step-by-step explanation:
Assume the first integer is
.
then we have the sequence for the 6 numbers:
their sum equals 519. so we have the equation
now solve it.
now that we know the value of
, we can find the sequence of the integers:
Answer:
No
Step-by-step explanation:
2*37 equals 74
(2*3)*7 is a different case. You first have to do what is inside the parentheses. 2*3 is 6. 6*7 equals 42. You wouldn't distribute in this case, because of the multiplication position and PEMDAS.
Hope this helps!
