Sarah is twice as old as Bill so 2X=50 and X=25 so Bill is 25. Bill is 25 and bill is 5 times older than his sister Jane so 5n=25 N=5 so Jane is 5 years old. Jane's mom is 12 time older than Jane so 12x5=60 and so

60-50=10 so the answer is 10

Given that S is the centroid of triangle MNO, find SQ.
DochEvi [55]

Answer:

First, we need to calculate for x. Since,

MP = PN

Thus,


3x-4 = x+4

2x = 8

x = 4


Next, we calculate for MS 

MS = 2x + 2 = 10


Since, MS = 2SQ

10 = 2SQ

Then,

SQ = 5 units


Therefore, the correct answer is B.

<h2>Answer:</h2>

The answer is 16.

<h2>Step-by-step explanation:</h2>

Since the 8x is positive, the equation  must have y as a positive number.

Let's see this!

An easy way to complete the square if you have the constants for x2 and

But not the non-variable number is to divide the x constant, and then square it.

Example:

\frac{8x}{2} \\\\4^2=16\\

The last number must be 16. Let's check it.

(x+4)^2=x^2+8x+16

If both cars in Exercise 62 are on one side of the plane and if the angle of depression to one car is 38∘ and that to the other
Sati [7]

The two cars lying on one side of the plane are 50 meters apart.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

let us assume that the height is 100 m. Let d represent the horizontal distance. For depression of 38°, Ф = 90 - 38 = 52°, hence:

tan(52°) = d / 100

d = 128 m

For depression of 52°, Ф = 90 - 52 = 38°, hence:

tan(38°) = d / 100

d = 78 m

Distance apart = 128 - 78 = 50 m.

The two cars lying on one side of the plane are 50 meters apart.
