Equation: a^2 + b^2 = c^2
18^2 + 16^2 = c^2
324 + 256 = c^2
C^2 = square root 580
Square root 580 reduces to 2 square root 145.
As a decimal that is: 24.08
Rounded to the nearest tenth: 24 inches.
I hope this helps! If it does please offer me the brainiest!
Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x

The gas mileage is usually expressed in terms of the ratio of the distance traveled of the vehicle to the amount of fuel used up. This is the basis of how far a vehicle could go according to its consumption of fuel. In this case, the gas mileage is:
Gas mileage = 254.6 miles/19 gallons
Gas mileage = 13.4 miles/gal
