I know that the scale factor is 2 and the missing value for x is 30
This is because 10*2=20
5*2=10
And 15*2=30
And what they’re multiplying by is 2 which is the scale factor
Answer:
i dont understand the question
Putting this in mathematical terms
(-5)x/2-5=-55
Multiplying throughout by ‘-1’
(5x)/2+5=55
5x/2=50
x=+20
Thus 20 is the required value of x.
