Answer: The Tree is 28 ft tall
How do we know this. To solve this problem we can use proportions.
4 → 3.5
x → 24.5
So now our unit number can be found doing 24.5 ÷ 3.5 = 7 So x ÷ 4 must also equall 7.
We can make equation: x ÷ 4 = 7
Know we can use our knowledge of finding x.
x = 7 × 4
x = 28
The tree is 28 ft tall.
Lets check our answer!
4 → 3.5
28 → 24.5
4 * 7 = 28
3.5 * 7 = 24.5
Step-by-step explanation:
i think its the first onne not sure
45 + 35x = 40x
45 = 40x - 35x
45 = 5x
45/5 = x
9 = x <=== they are the same cost at 9 nights
Answer:600m
Step-by-step explanation:speed =54×1000/3600=15m/s
Since speed =distance /time
Therefore distance =speed *time
=15*40=600m
