Answer: The letter x is often used in algebra to mean a value that is not yet known. it is called a variable or somethings an unknown in x + 2 = 7, x is a variable but we can work out its value if you try a variable does not have to be x though it could be y or w, or any letter, name or symbol. See: variable
Step-by-step explanation: and that's it! have a yummy cookie day! ◑﹏◐
Given:
bake sale at least $300
price of each pie is $6.00
let the number of pies be represented by x.
Write the inequality:
6x <u>></u> 300
Solve the inequality:
6x <u>></u> 300
<u>÷6 ÷6</u>
x <u>></u> 50
Graph the inequality.
y = 6x
x is the number of pies sold; x at least 50 and gradually increases.
y is the total sales
Step-by-step explanation:
x -2 -1 2 7
y -6 -6 -2 3
All y are in under root
Answer:
Step-by-step explanation:
I wonder if it is the minus that is causing the problem?
Let x = - 5
3*(-5) - 9
-15 - 9
This is a money question. If you are 15 dollars in debt and you spend another 9, where are you? (In the company of the American government. They do this all the time).
- 15 - 9 = - 24

Answer:
- interior: 175°
- exterior: 5°
Step-by-step explanation:
The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.
exterior angle = 360°/72 = 5°
The interior angle is the supplement of this.
interior angle = 180° -5° = 175°
The measure of one interior angle is 175°; one exterior angle is 5°.
