Answer:

Given: A number b minus 4.2 is less than -7.5.

Here, b is the number.

"less than" symbol is represented by '<'

"minus" means subtract.

"b minus 4.2" translated to  b - 4.2

Then, our inequality becomes;

b - 4.2 < -7.5

To solve for b;

Add 4.2 both sides we get;

b -4.2 + 4.2 < -7.5 + 4.2

Simplify:

b < -3.3

Therefore, an inequality for the given word sentence is,  b - 4.2 < -7.5

Pls help 25h²- 16t² factorise it​
noname [10]

Answer:

(5h-4t)(5h+4t)

Step-by-step explanation:

25h² - 16t²

adding  and subtracting 20ht from it        (√25 and √16 = 5x4 = 20):

25h² + 20ht - 20ht -16t²

factor:

(5h-4t)(5h+4t)

Nimfa-mama [501]

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.

Find the greatest common factor of 32 and 39
Stella [2.4K]

Answer:

1

Step-by-step explanation:

We will first find the prime factorization of 32 and 39. After we will calculate the factors of 32 and 39 and find the biggest common factor number .

32=2^5

39=3^1*13^1

-

List of positive integer factors of 32 that divides 32 without a remainder.

1,2,4,8,16

List of positive integer factors of 39 that divides 32 without a remainder.

1,3,13

We found the factors and prime factorization of 32 and 39. The biggest common factor number is the GCF number.

So the greatest common factor 32 and 39 is 1.
