Answer: The sum of 75.2+(57.376+24.8) is 157.376.
Explanation:
The commutative property of addition states that,

The associative property of addition states that,

The given expression is 75.2+(57.376+24.8).
First use commutative property of addition in the parenthesis.

Now use associative property of addition.

Now simplify the expression,


Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
Since 57x17=969 I did 969-942 and got 27 so there is 16 full rows and then 27 left over so that means it won’t be a full row but 27 extra seats will be filled. (If your wondering where the 17 came from that’s how many rows can be made that’s over 942 because if I did 57x16 it would equal 912 and I would not have had a full row of chairs)
(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
X/5 - 11 = -13
x/5 - 11 (+11) = -13 (+11)
x/5 = -2
x/5 (5) = -2(5)
x = -10
-10 is your number
hope this helps
Answer:
The correct answer is C.
Step-by-step explanation:
The given equation is;

This implies that;


Let us write in Cartesian coordinates by substituting;



Square both sides;

This implies that;
