Answer:
3 (5x+7) = 75
15x + 21 = 75
15x + 21 - 21 = 75 - 21
15x = 54
x = 3.6

Answer:
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Step-by-step explanation:
Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.
3/4 - 5/12
we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .
3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.
Now let us go to the second part which is the answer minus 5/12
4/12 - 5/12 = (4 - 5)/12 = -1/12
The final answer should be -1/12. This is another error that has been detected.
The correct answer combination should be as follows.
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Answer:
D
Step-by-step explanation:
An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.
Consider expression D
This will be undefined when
x + 5 = 0 ⇒ x = - 5 ← excluded value → D
1. Given: Note that on the top, it is shown right next to "given"
2. Vertical angles theorem: Angles vertically opposite of each other are congruent
3. Transitive Property: If ∠3 ≅ ∠2 (Given), and ∠2 ≅ ∠6, then ∠3 ≅ ∠6
