Given:
The expression is:
To find:
The value of the given expression by using Commutative and Associative properties of numbers.
Solution:
We have,
Applying parenthesis and brackets, we get
![=[13+(23+12)]+7](https://tex.z-dn.net/?f=%3D%5B13%2B%2823%2B12%29%5D%2B7)
![=[13+(12+23)]+7](https://tex.z-dn.net/?f=%3D%5B13%2B%2812%2B23%29%5D%2B7)
[Commutative properties of numbers]
![=[(13+12)+23]+7](https://tex.z-dn.net/?f=%3D%5B%2813%2B12%29%2B23%5D%2B7)
[Associative properties of numbers]
Using Associative properties of numbers, we get
[Associative properties of numbers]
Therefore, the value of the given expression 55.
Answer:
B) 4y - 2 - 3y = 6
Step-by-step explanation:
x = 4y - 2 Substitute this into the second solution
x - 3y = 6
4y - 2 - 3y = 6
The largest value of the sum based on the information will be 1055.
<h3>How to calculate the sum?</h3>
From the information given, the digits are 2, 3, and and 5 but not necessarily in the same order. The numbers that can be formed will be:
235
253
325
352
523
532
Therefore, the largest value of the sum will be:
= 532 + 523
= 1055

Answer:
5√2, 5
Step-by-step explanation:
in a 90 45 45 triangle, each leg is the same legnth
the hypotenuse of a 90 45 45 triangle is x√2
x being the measure of the leg
Answer:
y = (-5/2)x + 1
Step-by-step explanation:
y = (-5/2)x + c
When x = 2, y = -4
-4 = (-5/2)(2) + c
-4 = -5 + c
c = -4 + 5 = 1
y = (-5/2)x + 1
