Answer:
If the poster is enlarged by the scale factor 5/2 then,
length=12×5/2=30ft
And,
breadth=3×5/2=7ft
>>>>correct ans is 7.5 by 30
7.5 feet by 30 feet
Step-by-step explanation:
i believe you would take 12 and divide it by 2 and then multiply it by 5=30. And then do the same for 3. 3 divided by 2 =1.5 and 1.5 multiplied by 5 =7.5
The answer would be 7.5 feet by 30 feet
X = 4
3x=16-4
3x= 12
X=12/3
X= 4
Explanation:
cross multiply
divide both sides by 2
isolate variables
simplify
divide both sides by -6
-2/3(negative two over three)
-1+1/3 we cross multiply,which will be-3+1/3 =2/3
dose that make sense???
