Mathematics
1 answer:
neonofarm [45]3 years ago
8 0

Answer:

11

Step-by-step explanation:

As per attached diagram:

  • AC = AB + BC

Given

  • AC = 18, BC = 6x + 5 and AB = 5x + 2

To find the value of BC, we need to find the value of x:

  • 6x + 5 + 6x + 2 = 18
  • 11x + 7 = 18
  • 11x = 11
  • x = 1

Then

  • BC = 6*1 + 5 = 6+5 = 11

50 Points:
kodGreya [7K]

Answer:

(-2,3)

Step-by-step explanation:

For the point to be 2/3 of the way; it means it divides AB into the ratio 2 to 1

Now, we can use the internal section formula to get the coordinates of this point

(x,y) = (nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)

where (m,n) = (2,1)

(x1,y1) = (-4,-1)

(x2,y2) = (5,5)

(x,y) = (1(-4) + 2(-1)/(1+2), (1(-1)+2(5)/(1+2)

(x,y) = (-4-2)/3, (-1 + 10)/3

(x,y) = (-2,3)

Step-by-step explanation:

<u>Step 1: Define</u>

3t + 7 = 2 + 5t

<u>Step 2: Solve for </u><u><em>t</em></u>

  1. [Subtraction Property of Equality] Isolate <em>t</em> terms:                                        7 = 2 + 2t
  2. [Subtraction Property of Equality] Isolate <em>t</em> term:                                         5 = 2t
  3. [Division Property of Equality] Isolate <em>t</em>:                                                        5/2 = t
  4. Rewrite:                                                                                                             t = 5/2
