Answer: 18 and 36
Step-by-step explanation:
The scale is 8m for every 2 in and the actual area is 144m2 so we need to covert that into inches. You divide 144 by 8 which = 18 and then multiply 18 x 2 which is equal to 36.
Answer:
4 2/3 units cubed
Step-by-step explanation:
Since they didn't give the 3rd side length, but they gave us one side's area we can just do 3 1/3 times 1 2/5 which gives us 14/3 which then is reduced to 4 2/3 units cubed.
Oh and btw I see that's a khan academy question.
35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
