Answer:
<h2>x = 25</h2>
Step-by-step explanation:
a number
x
a number divided by 5
x/5
Seven less than a number divided by 5
x/5 - 7
Seven less than a number divided by 5 is -2
x/5 - 7 = -2
x/5 = -2 + 7
x/5 = 5
x = 5 * 5
<h2>x = 25</h2>
Answer:
The speed in scientific notation is 
feet per second.
Step-by-step explanation:
1. You have the following speed: One thousand one houndred feet per second.
2. You must convert from words to number. This is:
1,100 feet per second
3. To express this quantity in scientific notation, you can move the decimal point three places to the left, and write it as: 1.1 by 
(or 1,000) as following:
Answer:
1. 16 cm (squared)
3. 200 cm (squared)
Step-by-step explanation:
Answer:
1. x = 21
2. x = 19
Step-by-step explanation:
Since the interior angles of all quadrilaterals add up to 360, all we have to do is add them up and set them equal to 360. Combine like terms and we get
7x + 213 = 360
Which further turns to 7x = 147
So x = 21
For the second problem, it's the same thing
By the end we get 2x + 8 = 46
2x = 38
x = 19
Hope this helps
