Let x represent the first number, then x-7 represents the second number

Assume the numbers are whole numbers (no negative numbers), then the smallest value that x could be is 8. Thus, the first number is 8 and the second number is 1. The LCM is 8.

Let's increase x by one number so that x=9, then the second number is 2. The LCM is 18.

Let's increase x again by one number so x=10, then the second number is 3. The LCM is 30.

You could continue this to discover that the LCM will be x(x-7) between x=8 and x=13.

So what happens at x=14? First digit is 14 and the second digit is 7. The LCM is 14.

This will occur for all x-values that are multiples of 7.

Answer: when x is a multiple of 7, the LCM is x. when x is not a multiple of 7, the LCM is x(x-7).

Please help Solve 5(2x - 3) = 5x - 10 for c <br><br> A) 2<br><br> B) 1<br><br> C) 0<br><br> D) -1
bixtya [17]

Answer:

B

Step-by-step explanation:

Use distributive property:

5(2x - 3) = 5x - 10

10x - 15 = 5x - 10

Isolate the variable:

10x = 5x - 10 + 15

10x = 5x + 5

10x - 5x = 5

5x = 5

x = 1

a triangle has side lengths of (9.7m-6.8m) centimeters, (6.6m+6.5p) centimeters, and (2.2p-6.4n)centimeters. which expression re
Rashid [163]

Answer:

To find the perimeter of a triangle, you would need  first all three side lengths.  

9.7m-6.8m = 2.9, 6.6m+6.5p=7.1, 2.2p-6.4= -4.2. once I added all the sides it was 5.8.

Below are the supply and demand equations for blenders in a certain market. In these equations, p represents price, D represents
Reptile [31]

The value of p at the point of equilibrium, where supply and demand are equal, is 43.3 (the nearest tenth).

<h3>What is equilibrium point of supply and demand?</h3>

The equilibrium point of supply and demand is the point where, the value of demand of a product is exactly equal to the value of supply of that product.

The supply and demand equations for blenders in a certain market is given as,

D=\dfrac{-5}{8}p+35

S=\dfrac{6}{5}p-44

Here, in these equations, p represents price, D represents demand, and S represents supply.

At the point of equilibrium, the supply and demand are equal. Therefore,

D=S\\\dfrac{-5}{8}p+35=\dfrac{6}{5}p-44

Solve it further to get the value of p as,

\dfrac{6}{5}p-\dfrac{-5}{8}p=35+44\\\dfrac{6}{5}p-\dfrac{-5}{8}p=35+44\\p=\dfrac{3160}{73}\\p\approx43.3

Hence, the value of p at the point of equilibrium, where supply and demand are equal is 43.3 (the nearest tenth).
