Answer:
You have to translate these sentences into expressions. I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it. Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6
Step-by-step explanation:
Why? We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3. In this case we would input: 3*x, or 3x. 7 more than that number is 3x+7. Five times a number decreased by six: 5x-6 . Remember: it is simply 5*x which simplifies to 5x. Decreased is take away, so take away 6, and get 5x-6
Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)
I hope you understand!! It is very simple after you start to get the hang of it!!
<span>1017.88 if you use the formula for the area of a circle which is </span>πr²
Answer:
See below
Step-by-step explanation:
<u>Number of squares:</u>
- 1x1 squares = 8*8
- 2x2 squares = 7*7
- 3x3 squares = 6*6
- 4x4 squares = 5*5
- 5x5 squares = 4*4
- 6x6 squares = 3*3
- 7x7 squares = 2*2
- 8x8 square = 1
<u>Total number:</u>
- 8² + 7² + 6² + 5² + 4² + 3² + 2² + 1 =
- 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 =
- 204
