Answer:
x = -7
Step-by-step explanation:
So we are asked to find what x is equal to in the equation:

In other words, we are asked to solve for x.

Add 4 to both sides of the equation.

Multiply both sides by 7.
x = -7
So we have solve the equation for x and have found that x = -7.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
9 + f = 16
Step-by-step explanation:
So just say 9 + f = 16 since the tree grew to 16, and the f is the amount.
We know that
speed=distance/time
1) <span>Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr
time=2 1/6 hrs----> 13/6 hrs
speed=6 km/h
distance=speed*time----> 6*(13/6)---> 13 km
2)</span><span>for another 2 hours and 5 minutes with a constant speed of 12 km/hr
time=2hrs+5 minutes----> 2+(5/60)--> 125/60 hrs
speed=12 km/hrs
distance=speed*time----> 12*(125/60)---> 25 km
3) find the </span><span>average speed for the total trip
total distance=13 km+25 km----> 38 km
total time=(13/6)+(125/60)----> (10*13+125)/60----> 4.25 hours
speed=38/4.25----> 8.94 km/hrs
the answer is
8.94 km/hrs</span>
The given statement is "nine times five less than twice x".
So, twice of x can be written as 2x and nine times five is 9*5.
Now 9*5 less 2x means we need to take out 9*5 from 2x.
Hence, this statement will be converted into an algebraic expression as follows:
2x-9*5
Answer:65
