Answer:
Communitive Property
Step-by-step explanation:
Commutative property = 2 + 3 = 3 + 2 or 2(3) = 3(2)
Associative Property = (2 x 3) 5 = 2 (3 x 5) or (2 + 3) + 5 = 2 + (3 + 5)
Inverse Property = 2 + (-2) = 0 or (2/1)(½) = 1
Basic Definitions:
<u><em>Commutative Property</em></u> - Gives you the ability to switch the order of the numbers in an expression.
<u><em>Associative Property</em></u> - Let's you move the parenthesis in an expression but not the numbers.
<u><em>Inverse</em></u> - Uses numbers like 0 and 1.
Using these basic definitions and examples, we can summarize that the best answer would be <u>Communitive Property</u>

Answer:
$10.25
Step-by-step explanation:
Set up a system of equations, so 3c + 2m = 7 and 2c + 4m = 8, where c = the cost of coffees, and m = cost of muffins
To solve multiply the first equation by -2(3c + 2m=7) so you get -6c -4m = -14 now add the two equations
-6c - 4m = -14
2c + 4m = 8 notice that -6c + 2c = -4c and -4m + 4m cancels, then -14+8=-6
so we have -4c = -6 so c = $1.50
To solve for m, substitute c = 1.50 so 3(1.50) + 2m = 7, so solve for m so
4.5 + 2m = 7, 2m = 2.5, so m = $1.25
So now solve the final problem 6(1.50) + 1(1.25) = $10.25
Answer:
See below
Step-by-step explanation:
<u>We can estimate the dividend and divisor as follows:</u>
- 635943 ÷ 77 =
- 636000 ÷ 80 =
- 7950 ≈ 8000
Estimate is 8000
