Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11
1- If the other 5 numbers on the cube aren't 3 the probability is 1/6
2-(Sorry I don't speak English well and I didn't understand the question) I think it's refereed to the first sentence, so it's 67/450=1/75
Answer:
<em>The value of b is</em><em> 8</em><em>.</em>
Step-by-step explanation:
The given function is,
The given data is,
i.e when the value of x is -2, then the value of the function is -14.
Putting all the values,
Therefore, the value of b is 8.
m∠RSV = 3x + 5, m∠RST = 8x - 14 <em>given</em>
m∠RSV ≅ m∠VST <em>definition of segment bisector</em>
m∠RSV + m∠VST = m∠RST <em>angle addition postulate</em>
(3x + 5) + (3x + 5) = (8x - 14) <em>substitution</em>
6x + 10 = 8x - 14 <em>simplify (added like terms)</em>
10 = 2x - 14 <em>subtraction property of equality</em>
24 = 2x <em>addition property of equality</em>
12 = x <em>division property of equality</em>
Answer: x = 12
