Two equations are:
Te is time east
Tn is time north

Te + Tn = 5 hours
266Te +196Tn = 1190 is the distance equation

Solve these two equations and
Te = 3 hours and Tn= 2 hours

7m + -10 =-10 what is m?
tigry1 [53]

Answer:

m = 0

Step-by-step explanation:

Given

7m + -10 = -10

Positive negative gives negative.

So the expression can be rewritten as

7m - 10 = -10

Add 10 to both sides of the equation

7m - 10 + 10 = -10 + 10

7m = 0

Divide both sides by 7

7m /7 = 0/7

m = 0

Can someone help? This is so hard
Sunny_sXe [5.5K]

Answer:

#1 x = 31°

#2 x = 125°

Step by Step Explanation:

#1

  • By the theorem of intersecting secants outside of the circle, we have:

  • x=\frac{1}{2}(103\degree-41\degree)

  • \implies x=\frac{1}{2}(62\degree)

  • \implies \red{\bold{x=31\degree}}

#2

  • By the theorem of intersecting chords, we have:

  • x=\frac{1}{2}(96\degree+154\degree)

  • \implies x=\frac{1}{2}(250\degree)

  • \implies \purple{\bold{x=125\degree}}

The three sides of a triangular lot are represented by x , 2 x , and 3 x + 2. Find each side if the perimeter of the triangular
Leona [35]

Answer:

60 ft, 120 ft, 182 ft

Step-by-step explanation:

Hi there,

To find the perimiter of a polygon, you need to add of all of the sides.

So, let's do that:

x + 2x + 3x+2

Since we are given the perimeter, we make what we just did above, equal to the perimeter

x + 2x + 3x +2 = 362

Combine lke terms...

6x + 2 = 362

Subtract 2 from both sides to start to isolate the variable...

6x = 360

Divide both sides by 6 to isolate x...

x = 60

But we're not done yet...

The length of the first side is 60 ft, the length of the second side is 2*60 which is 120 ft, and the length of the third side is 3*60 + 2 which is 182 ft.

Let's check...

Does 60 + 120 + 182 = 362?

362 = 362

Our answers are right

Hope this helps! Stay safe!
