Answer:

23.9

Step-by-step explanation:

His route from school to Rhianna's house to his house forms a triangle in which the sides are 7 miles and the hypotenuse is unknown. Solving using the Pythagorean theorem, we find the route from Rhianna's house back home is 7^2+7^2=x^2.

Rounding to the nearest tenth, we now know this route is 9.9 miles. Adding the total distances from each location, we get an answer of 7 + 7 + 9.9 = 23.9.

For what value of x does 34x=27x-3
Anit [1.1K]

Answer:

<h2><u>x=−3/7</u></h2>

Step-by-step explanation:

Let's solve your equation step-by-step.

34x=27x−3

Step 1: Subtract 27x from both sides.

34x−27x=27x−3−27x

7x=−3

Step 2: Divide both sides by 7.

7x\7=−3\7

x=−3/7

Determine the constant of varlation for the direct variation glven. Rvaries directly with S. When S is 16, R Is 80.​
navik [9.2K]

Answer:

The constant of variation is 5.

Step-by-step explanation:

In direct variation, as y varies directly with x, the standard equation is

y = kx,

where k is the constant of variation.

In your case, we use R and S. R varies directly with S, so we have

R = kS

We know that when S = 16, R is 80, so we plug in those values and solve for k, the constant of variation.

R = kS

80 = k(16)

k = 80/16

k = 5
