Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)

Can someone explain this to me I need help T_T

Answer: 6,800,000 people

Step-by-step explanation:

We are looking for the number of people, not the percentage of wealth that has been made up by the people.

2% of the people are the richest in the United States, and there are 340,000,000 people in total in the United States.

2% = 0.02

340,000,000 * 0.02 = 6,800,000

I hope this was helpful! :)

Step by step explanation need it
nasty-shy [4]

Answer:

8/17

Step-by-step explanation:

The sine of an angle is defined as the opposite side to the reference angle divided by the hypotenuse.

The side opposite the angle is always the side not connected to the reference angle. In this case the opposite side = ZY

The hypotenuse = XZ

Sin(X) = ZY/XZ

Sin(X) = 1634 = 8 / 17

The area of a rectangle is 42 square feet.
Alchen [17]

Answer:

26 ft and 46 ft.

Step-by-step explanation:

The prime  factors of 42 are 2 * 3 * 7.

Possible lengths and widths  are:

L = 7, W = 6 giving a perimeter of  2*7 + 2*6 = 26 ft.

L = 14 , W = 3  giving perimeter = 34 ft.

L = 21, W = 2 giving perimeter = 46 ft.
