Answer:

Simplifying

7 + 3lnx = 15

Solving

7 + 3lnx = 15

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 3lnx = 15 + -7

Combine like terms: 7 + -7 = 0

0 + 3lnx = 15 + -7

3lnx = 15 + -7

Combine like terms: 15 + -7 = 8

3lnx = 8

Divide each side by '3nx'.

l = 2.666666667n-1x-1

Simplifying

l = 2.666666667n-1x-1

Solve the inequality. Graph the solution. Describe the graph in the area provided. Be sure to indicate where there is an open or
natka813 [3]

Step-by-step explanation:

The given inequality is :

-27\ge \dfrac{1}{2}(6x-12)

Solving RHS of the inequality:

-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)

Adding 6 both sides of the inequality

-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7

The attached figure shows the graph for the given inequality.

Can someone help me answer this please
Citrus2011 [14]

Answer:

N = 3/8

Step-by-step explanation:

let the number be N

let's express the word sentence as a mathematical expression:

"a number multiplied by 2/5"

= "N" multiplied by 2/5

= N x (2/5)

= (2N/5) ------- (1)

"a number multiplied by 2/5 is 3/20" can be written as:

(2N/5)    =  3/20  (multiplying both sides by 5)

2N = (3/20) x 5

2N = 3/4      (divide both sides by 2)

N = (3/4) ÷ 2

N = (3/4) x (1/2)

N = 3/8
