Answer:
<h2>(-8.3x + 4) - (3.2x - 5) = -11.5x + 9</h2>
Step-by-step explanation:
(-8.3x + 4) - (3.2x - 5)
= -8.3x + 4 - 3.2x - (-5)
= -8.3x + 4 - 3.2x + 5 <em>combine like terms</em>
= (-8.3x - 3.2x) + (4 + 5)
= -11.5x + 9
Given that,
∠C = (6x-21)° and ∠A = (4x+11)°
To find,
Choose the correct option.
Solution,
For a parallelogram, the opposite angles are equal. ATQ,
(6x-21)° = (4x+11)°
Taking like terms together,
6x-4x = 21 + 11
2x = 32
x = 16
∠C = (6x-21)° = 6(16) -21 = 75°
So, ∠A = 75°
So, ∠A = ∠C = 75°. Hence, the correct option is (B).
Answer:
a. $8625
Step-by-step explanation:
So there are 115 members and they each raise $75.
That means one member would raise $75, the second member would raise another $75, the third would raise another $75 etc....
So you just have to multiply 115 and 75 together and that gives you $8625
