Answer:
x = 42 - 4
x = 38
Step-by-step explanation:
Given that :
Initial number of plane models = x
Number of additional models built = 4
Total number of planes = 42
Total = initial amount + additional amount
42 = x + 4
Make x the subject
42 - 4 = x + 4 - 4
x = 42 - 4
X + 4 = 42
X = 42 - 4
X = 38
8.) (10 / 5) × 100% = 200%
9.) <span> </span>40 x 100<span> / </span>60<span> = </span><span>66.666666666667</span>
10.) 9% × 80 = (9/100) × 80 = 7.2

Answer:
I don't get it really, sorry.
Step-by-step explanation:
This question is very difficult to understand because of the wording, is there anything else, such as any multiple choice answers or any more information that I could use to assist in your question. As I read it, it says 1 cm : 100 km. And the distance between those two would be 1160 miles. 1160/100=11.6, and 11.6≈11.6 so yes, I dont know what to say. The question answers the answer. Let me know if you understood something that I didn't understand and we can go from there. Hope I could be of some help, even know I don't know what to say.
