Step-by-step explanation:

N = 4(12) = 48 novels

Answer:V=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12v+10v+14=80

(12v+10v)+(14)=80

(Combine Like Terms)

22v+14=80

22v+14=80

Step 2: Subtract 14 from both sides.

22v+14−14=80−14

22v=66

Step 3: Divide both sides by 22.

22v/22=66/22

V=3

Distance = (Rate)(Time)

Let x = speed of slower train

     x + 17 = speed of faster train

The trains meet when the sum of the distances = 1285

5x + 5(x+17) = 1285

(5 came from 5 hours)

10x + 85 = 1285

10x = 1200

 x = 120 mph

The speeds are 120 mph and 137 mph

The degree of a polynomial is the highest power among its terms .

i.e 8 for the above expression :

9x² + 3x⁸ + 6x + 586 - 7x⁵

Answer:

Ok. so let's teach you how to find the angles of a triangle. When you add all three sides, they must equal 180 degrees. Because of this, let's do some math. What is 96+35. Ima pretend you said 131 and so you would be right. Now let's subtract that from 180 degrees. 180-131 is 49 and so x is 49 degrees. Hope this helps!!

There is no three-digit whole number that has exactly five positive factors.

The prime factorization of a number with five factors will be of the form p⁴ or p²q, where p and q are distinct prime numbers.

p⁴:

The smallest prime number greater than or equal to 10 is 11.

So, let's consider 11⁴:

11⁴ = 14641 (which is a five-digit number)

p²q:

To minimize the number, we need the smallest prime numbers possible. The two smallest prime numbers greater than 10 are 11 and 13.

Let's consider the product of these two primes:

11² × 13 = 1573 (a four-digit number)

The difference between the freezing point of water and mercury is 70°F.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that mercury has a freezing point of -38°F and water has a freezing point of 32°F.

The difference between the freezing point of water and mercury is calculated below

Difference =  freezing point of water -  freezing point of mercury

Difference =  32 - ( -38)

Difference =  70°F

Therefore, the difference between the freezing point of water and mercury is 70°F.

Answer:

8

Step-by-step explanation:

4(x-3) -2(x+1) =2​

=> 4x - 12 - 2x - 2 = 2      [opening brackets]

=> 4x - 2x - 12 - 2 = 2

=> 2x - 14 = 2

=> 2x = 14 + 2

=> 2x = 16

=> x = 16/2

=> x = 8

4 ( x - 3 ) - 2 ( x + 1 ) = 2

2 ( x - 3 ) - ( x + 1 ) = 1

2x - 6 - x -1 = 1

2x - x = 1 + 6 + 1

x = 1 + 6 + 1

x = 7 + 1

x = 8
