= 10
6/10 = 3/5
Simply divide the numerator and denominator of 6/10 by 2. 6/10 is the same as 3/5.
The GCF of 8x and 40 is 8
The cross products of the proportion are equal.
According to the question, Sonny's equation can be written as follows.
16/x = 48/15
Now, the variable x is replaced by the constant 5. So the equation can now be written as follows.
16/5 = 48/15
When two fractions are equal to one another as shown above, the constants are cross multiplied with one another in order to form an equation.
16*15= 48*5
The values of both the products are equal which is 240.
Therefore, because the cross products of the proportion are equal.

Answer:
(A) x=-28
Step-by-step explanation:
237 -6x = 405 [note that 6*(-x) is (-6x)]
-6x = 168 [subtract 237 from both sides]
x = -28 [divide both sides by (-6)]
