First you would add 2z to both sides
6k = 12 + 2z
second divide 6 from both sides
K = (12 + 2z) / 6
^^ thats your answer :)
<h3>Answer:</h3>
- no
- yes
- no
- yes
- yes
<h3>Explanation:</h3>
The distributive property is useful both for collecting terms and for eliminating parentheses.
1. 3x +1/4 -x +1 1/2 = x(3 -1) +(1/4 +1 2/4) = 2x +1 3/4 ≠ 4x +1 3/4 (no)
2. 2(3x+1) = 2·3x + 2·1 = 6x +2 = 2 +6x (yes)
3. 3(x+1) -(1+x) = (x+1)(3 -1) = 2(x+1) = 2x +2 ≠ 2x +3 (no)
4. 4(x+1)-x-4 = 4x +4 -x -4 = x(4-1) +(4-4) = 3x +0 = 3x (yes)
5. 5.5 +2.1x +3.8x -4.1 = x(2.1 +3.8) +(5.5 -4.1) = 5.9x +1.4 = 1.4 +5.9x (yes)
Answer:
the awnser is C because the other awnsers don't exactly make sense
Step-by-step explanation:
just kinda mental math
Answer:
Soz idk it but you should use math-way!!
Step-by-step explanation:
The lowest common multiple or least common multiple is the lowest multiple two numbers have in common.
you could either:
•list the multiples
eg. What is the lowest common multiple of 2 and 3?
Multiples of 2: 2, 4, 6, 8...
Multiples of 3: 3, 6, 9...
The lowest common multiple of 2 and 3 is 6.
• or factors.
eg. The prime factors of 25 are 5 x 5.
The prime factors of 30 are 2 x 3 x 5.
Remove the 5 that 25 and 30 have in common as a prime factor.
Multiply 25 by the remaining prime factors of 30.
25 x 2 x 3 = 150.
The lowest common multiple of 25 and 30 is 150.
that’s not how to find the lowest of those numbers, but that’s how to do it :))
