Answer:

A = 60°

Step-by-step explanation:

First to find the missing angle you add the three known angles,

90 + 135 + 75 = 300

Then, you subtract, 360 - 300 = 60

<h3>So, 360° = 60° + 90° + 135° + 75°</h3><h3 />

Function,d(r) = 0.034r , is used to convert Russian rubles in United States dollars, and function, e(d) = 0.76d , is used to con
Dahasolnce [82]
We have two functions, one which converts rubles to USD and one which converts USD to euros. If we want to convert from rubles to euros, we could just convert it to USD and then euroes.

2000₽ ⇒ USD
d(r)=0.034r\\d(2000)=0.034(2000)=68

$68 USD ⇒ €
e(d)=0.76d\\e(68)=0.76(68)=\boxed{51.68}

Extra: If you wanted, you could create a function to convert rubles into euroes.
Just substitute that 0.034r for d in e(d) = 0.76d and...e(r)=0.76(0.034r)=0.02584r

Factor (8xy)(3x-7y) on standard form
photoshop1234 [79]

Answer:

Step-by-sThe standard form is Ax + By = C

with A being both positive and non-fraction

so we are given 3x - 9 = 7y

we add the 9 to both sides

3x = 7y + 9  

and subtract the 7y from both sides

3x - 7y = 9
