Convert y=27.00x+138.00
and
y=40.00x+47.00
back to points please...and show how you did it.

8 2/3 is the answer

step-by-step explanation: just use a calculator

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
