I think x = 60° , because two sides of the triangle are equal , it means their angles are equal too
Answer:
<u>Let's solve for x.</u>
−5x + 4y = 3
<u>Step 1: Add -4y to both sides.</u>
−5x + 4y+ −4y =3+ −4y
−5x = −4y +3
<u>Step 2: Divide both sides by -5.</u>
-5x divided by 5 = -4y+3 divided by -5
x=4/5y + −3/5

Answer:
The expected value of this game to me is 5 odd x $5 = $25.
There is 1/2 chances of winning and losing.
The expectations after playing 100 times is 100x5 oddx$5=$2500
Step-by-step explanation:
Odd is the probability or likelihood of an event occurring.
Answer:
a) 2x + 8 = 2(x + 4) has infinite solutions because it simplifies down to x = x. Here is the work where this equation is solved.
2x + 8 = 2(x + 4)
2x + 8 = 2(x) + 2(4)
2x + 8 = 2x +8
2x + 8 - 8 = 2x + 8 -8
2x = 2x
2x/2 = 2x/2
x = x
So, because the equation ends in x = x, you can substitute any value for x and the equation will remain true.

b) 3x + 7 = 3(x + 7) has no solutions because it simplifies down to an untrue statement. The equation is simplified below.
3x + 7 = 3(x + 7)
3x + 7 = 3(x) + 3(7)
3x + 7 = 3x + 21
3x + 7 - 7 = 3x + 21 - 7
3x = 3x + 14
3x/3 = 3x/3 +14
x = x + 14
However, this is false. x cannot be equal to itself plus 14.
x ≠ x + 14
The simplification of this equation is untrue, so there is no solution to it.

I hope this is helpful :) Good luck
