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.

Answer:
90° CCW
Step-by-step explanation:
The transformation from B to B' is ...
B(-4, 1) ⇒ B'(-1, -4)
(x, y) ⇒ (-y, x) . . . . . matches the transformation for 90° CCW
For this case we have the following system of equations:

When solving the problem graphically we must take into account the following:
1) The solution of the system of equations is given by the intersection of both functions.
2) The solution is an ordered pair of the form (x, y)
For this case we observe that the solution is given by:

Note: see attached image.
Answer:
The approximate solution to the system is (1.23, 4.39)
Answer:
a = -27
d = -21 - ( -27) => 6
a62 => a + 61 (d) +=> -27 + 61(6)
=> -27 + 366
=> 339
