Answer:

Step-by-step explanation:

Let x = the age of Thomas

Let x + 6 = the age of Huilan

x + x + 6 = 70

2x + 6 = 70

2x = 64

x = 32 years

x+6 = 38 years

The question was incomplete. Below you will find the missing content.

In the figure below, BL, AM, and CK are medians of △ABC. If KC = 108 and OC = 2n + 10, then n=

The picture is attached below.

The value of n is 31.

The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.

The intersection of all 3 medians of the triangle is called the centroid.

As we know centroid divides the median in the ratio of 2:1.

In the given picture,

Medians of triangle △ABC are AM, BL, and CK.

So the centroid of the triangle is O.

Given that KC= 108

As the centroid O divides the line KC in 2:1.

Let OC=2x

KO= X

As KC= KO+OC

⇒ 108= x+2x

⇒ 3x=108

⇒ x=108/3

⇒ x=36

Then OC= 2x= 2*36= 72

As given in the question OC= 2n+10

putting the value of OC in above equation

⇒ 72= 2n+10

⇒ 2n= 72-10

⇒ 2n=62

⇒ n=62/2

⇒n=31

Therefore the value of n is 31.

Tell me the y-intercept of the line: 2x - 3y = 9
butalik [34]

Answer:

y-intercept: (0,-3)

Step-by-step explanation:

  • Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:

  • 2(0)-3y=9\\0-3y=9\\-3y=9\\y=\frac{9}{-3} \\y=-3

  • Therefore, the point is (0,-3).
