3(0.7z+2.8)=7(1.5z+7.2)

AnnZ [28]

Answer:

z = -5

Step-by-step explanation:

3(0.7z + 2.8) = 7(1.5z + 7.2)

2.1z + 8.4 = 10.5z + 50.4

2.1z - 10.5z = 50.4 - 8.4

-8.4z = 42

z = 42/(-8.4)

z = -5

kifflom [539]

Answer:

2.73 million people per year

Step-by-step explanation:

Turn sentences into coordinates/points:

In 2000, 281.4 million people

(x₁, y₁) = (2000, 281.4)

In 2010, 308.7 million people

(x₂, y₂) = (2010, 308.7)

Rate of population per year:

$\sf \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\rightarrow \sf \dfrac{308.7-281.4}{2010-2000}$

$\rightarrow \sf 2.73 \ million \ people$

A mountain bike has a diameter of 26 inches. To the nearest foot how far does the tire travel when it makes 32 revolutions?

Tcecarenko [31]

Hello!

You have to find the circumference

You use the equation

$2 \pi r$

r is radius which is half the diameter

This gives us 81.68

Multiply this by 32

81.68 * 32 = 2613.76

This is 217.8133333 feet

The answer is 217.8133 feet

Hope this helps!
