Answer:

my answer was 7.5

Step-by-step explanation:

2b+3b-10

4b+3b-10

10-7b=3b fraction bar means divide so...

__ 2

4b because... b-2b=4b and 8-4b=4b

3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)

Arrange these numbers in increasing order: 216,000,000, 2.2 × 10 to the 3rd power, 3.1 × 10 to the 7th power, 310,000

ziro4ka [17]

216,000,000
2.2 × 10 to the 3rd power = 2.2 * 10^3 = 2,200
3.1 × 10 to the 7th power = 3.1 * 10^7 = 31,000,000
310,000

Increasing order:
2,200 , 310,000 , 216,000,000 , 31,000,000

So increasing order with original numbers:
2.2 × 10 to the 3rd power, 310,000, 216,000,000, 3.1 × 10 to the 7th power

Using the given points, determine the slope. (0, 32) and (100, 212)

Allushta [10]

Hi!

To find the slope of two given points, subtract the y values, and subtract the x values, or..

$\frac{(y2 - y1)}{(x2 - x1)}$

$\frac{(212 - 32)}{(100 - 0)}$

$\frac{180}{100}$

The answer is 9/5 or 1.8.

Hope this helps! :)
