Does this equation have one solution, unlimited, or none? If its one (its not unlimited) show your work so I can understand it.
Musya8 [376]

Answer: none

1) combine like terms: 4x + 8 = 4x - 13

2) Add 13 to both sides (addition property of equality)

3) Subtract 4x from both sides (subtraction property of equality)

4) 21 does not equal 0

Complete the proof....
abruzzese [7]

Answer:

The correct options are;

1. Definition of supplementary angles

2. m∠1 + m∠2 = m∠1 + m∠3

3. m∠2 = m∠3

4. Definition of Congruent Angles

Step-by-step explanation:

The two column proof is presented as follows;

Statement           {}                                  Reason

1. ∠1 and ∠2 are supplementary    {}     Given

 {} ∠1 and ∠3 are supplementary

2. m∠1 + m∠2 = 180°        {}                    Definition of supplementary angles

{}   m∠1 + m∠3 = 180°

3. m∠1 + m∠2 = m∠1 + m∠3      {}          Transitive Property

4. m∠2 = m∠3       {}                               Subtraction Property of Equality

5. ∠2 ≅ ∠3       {}                                    Definition of Congruent Angles

Given that angles ∠1 and ∠2 are supplementary angles and angles ∠1 and ∠3 are are also supplementary angles, then the sums of m∠1 + m∠2 and m∠1 + m∠3 are equal, therefore, ∠2 and ∠3 have equal quantitative value and therefore ∠2 = ∠3 and by definition, ∠2 ≅ ∠3.

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal
frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)=\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)=1 - 0.99^{50}=0.395

I just need Y. I already found X
garri49 [273]
Y = 54.

This is really complicated to explain, but since x is 36 and the angle on the other side of the known angle is also 36, that makes y 54. Each pair of angles has to equal to 90 degrees.

Hope this helps!
