Answer:
15
Step-by-step explanation:
If CD and DE equal, then x+6 = 4x -21
So if you subtract x from both sides and plus 21 to both sides, that would be 3x = 27. Divide by 3 on both sides and you get 9.
Plug in x+6 with 9 and you get 15.

Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6

Answer:
211.1
Step-by-step explanation:
3 isn't greater than or equal to 5 so it will not round up to 2 so your answer will be 211.1
<span> A toy jeep is 12 1/2 inches
Actual jeep is 18 ¾ feet long
before we determine the ratio, let’s convert first each size into the same unit
of measure and decimal points
=> 12 ½ = 25/2
=> 12.5 inches
=> 18 ¾ = 75/4
=> 18.75 feet
Now, let’s convert feet to inches to know the ratio
=> 1 foot = 12 inches
=> 12.5 inches : 225 inches
=> 225 / 12.5
=> 18 inches
thus in every 1 inch of toy car represents 1.5 feet of actual car.
