which system of equations has no solutions? please help will mark brainliest!!!

Answer:

The country's population decreased about 5.8 % during this time period.

Step-by-step explanation:

Population in 1990 = 164 million

Population in 2010 = 155 million

Determine the percent decrease

The formula used is: [tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100[/tex]

We have :

Initial Value = 164 million (164,000,000)

New Value = 155 million (155,000,000)

Finding percent decrease

[tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100\\Percent\:Decrease=\frac{164,000,000-155,000,000}{155,000,000}\times 100\\Percent\:Decrease=\frac{9,000,000}{155,000,000}\times 100\\Percent\:Decrease=5.8\%[/tex]

So, The country's population decreased about 5.8 % during this time period.

Answer:

Smallest number is 18. Largest number is 30.

Step-by-step explanation:

a:b:c = 4:5:3

∃x such that a = 4x, b = 5x, c = 3x

"sum of the numbers is 72"

a+b+c = 4x+5x+3x = 72

x = 6

a = 4x = 24

b = 5x = 30

c = 3x = 18

Answer:

I think the perimeter of the diagram is 5 and if you round it like

If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. (In the example above, the hundredths digit is a 4 , so you would get 51.0 .) To round a number to the nearest hundredth , look at the next place value to the right (the thousandths this time).

Answer:

[tex]\huge\boxed{\sf 320\ servings = 4\ gallons}[/tex]

Step-by-step explanation:

1 gallon = 16 cups (STANDARD)

For 10 servings:

10 servings = 2 cups of water

10 servings = 2 / 16 gallons

10 servings = 0.125 gallons

For 320 servings:

10 servings = 0.125 gallons

Multiply both sides by 32

10 * 32 servings = 0.125 * 32 gallons

320 servings = 4 gallons

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Answer: The answer is 4 gallons.
