Answer:
GIVEN :
Patti is using mental math to evaluate the expression (70 + 12.8 + 30) + 6.1
TO FIND :
The properties of operations allow Patti to simplify.
SOLUTION :
Given that Patti is using mental math to evaluate the expression (70 + 12.8 + 30) + 6.1.
Option d) She can use the commutative property to rewrite the expression as (70 + 30 + 12.8) + 6.1 is correct.
For :
Patti's expression is (70 + 12.8 + 30) + 6.1
By using the commutative property of addition
a+b=b+a
(70 + 12.8 + 30) + 6.1
= (70+30+12.8)+6.1 (here a=12.8 and b=30)
∴ the properties of operations allow Patti to take is the commutative property of addition.
Answer: x =168
Step-by-step explanation:I think it would be 80 plus 88 so its 168.
Answer:
<u><em></em></u>
<u><em></em></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the trigonometric function

we know that sin²∝ + cos²∝ = 1
⇒ sin²∝ = 1- cos²∝
Now we have to simplify the given trigonometric function
= 
= 
<u><em>Step(ii)</em></u>
we know that cosec∝ = 1/ sin∝
= 
After cancellation sine function, we get
= 
<u><em>Final answer:-</em></u>

I'm not fully sure what you are asking but it could be represented by +160.
Answer:
A. y≤-x+3
y≤ x²-3x
Step-by-step explanation:
Both inequality shadings of the graphs are below the solid lines, which means that y is less than or equal to both of them.
