On a car trip Sam drove m miles Kara drove twice as many miles as Sam and Darin drove 20 fewer miles than Kara in terms of m many miles did Darin drive

Answers

Answer:

Darin drove '2m - 20' miles.

Step-by-step explanation:

We are given that Sam drove 'm' no. of miles.

As, it is also given that Kara drove twice as many miles as Sam. Therefore we get that Kara drove '2m' no. of miles.

Now, it is given that Darin drove 20 miles fewer than Kara .i.e. Darin drove '2m - 20' no. of miles.

Hence, in terms of m, Darin drove '2m - 20' miles.

Angles C and E are supplementary. The M>C = 112 and M>E = (3x + 50) Solve for X.

Answers

Answer:

The value of x is 6

Step-by-step explanation:

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

so

In this problem

m∠C+m∠E=180°

we have

m∠C=112°

m∠E=(3x+50)°

substitute and solve for x

112°+(3x+50)°=180°

3x+162=180

3x=180-162

3x=18

x=6

In the right triangle ABC

Applying the Pythagorean Theorem

AC^2=AB^2+BC^2

we have

BC=CE-EB=9.3-2.4=6.9\ in

AB=DE=26.5\ in

substitute

AC^2=26.5^2+6.9^2

AC^2=749.86\nAC=27.4\ in

therefore

The distance between the centers of the gears is 27.4 inches
