Answer:
x = -19
Step-by-step explanation:
-3= 12x-5(2x-7)
Distribute
-3= 12x-10x+35
Combine like terms
-3 = 2x +35
Subtract 35 from each side
-3-35 = 2x+35-35
-38 = 2x
Divide each side by 2
-38/2 = 2x/2
-19 =x
first you divide14 and 5 and you get 2.8 then you turn 2.8 into 2 8/10
2 8/10 is your answer
4/10 cookies so that is 2/5 or 40% :)
Answer: abe
Step-by-step explanation: start at origin and is proportional
The height of the smaller rectangle, let us say is 5
5 x 4 = 20
(multiply height of rectangle to scale factor)
the length is 4
4 x 4 = 16
(multiply length of rectangle to scale factor)
to find larger factor, divide smaller with larger
16/20 = 1/4
scale factor should be 1/4
multiply 20 with 4
perimeter of larger should be 80
hope this helps
