You don't say if the answer needs to be rounded
the height is 77.27 meters ( not rounded)
see attached picture for solution:
I would start by plugging in a number for x. Just any random number. Let's take 2 for example. Then the equation would go from 2x + y = -4, to 2(2) + y = -4. Then solve.
2(2) + y = -4
4 + y = -4, after you've done that, plug in a number for y, that completes the equation. In this case, the only acceptable number, would be -8. Because it completes the number sentence.
4 + (-8) = -4
-4 = -4.
Now plug in other numbers, to get the same outcome. Hope this helped!

Answer:
110.5
Step-by-step explanation:
208=13+(3-1)d
208=13+2d
-13. -13
195=2d
÷2. ÷2
97.5=d. (d means difference)
13(first term)+97.5=110.5
A sailboat travels 3 miles in 1.5 hours. How far does it travel in 2 hours.
= 3 miles / 1.5 hours
= 2 miles per hour
= (2 miles) * (2 hours)
= 4 miles in 2 hours.
So, in conclusion, if a sailboat travels 3 miles in 1.5 hours, it travels 4 miles in 2 hours.
The cost of the bench is $150.
300÷2= 150
150+300= 450
Hope this helps! :)
