Well, you know that the sum of those two numbers aren't zero, as they aren't additive inverses of each other. The sum of these numbers will, furthermore, take the sign of the "greater" number without its sign. For example, 2-3 would be negative, since the negative sign of "3" is of the greater number without its sign.

Answer:
The answer to your question is: x = 32
Step-by-step explanation:
Data
x = ?
It is an equilateral triangle so, the three angles measure the same
2x - 4 = 5y
2x - 5y = 4
The sum of the internal angles in a triangle equals 180°
3(5y) = 180
5y = 180/3
5y = 60
y = 12
2x - 4 = 5y
2x - 4 = 5(12)
2x = 60 + 4
2x = 64
x = 64/2
x = 32
Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
