Answer:
4
Step-by-step Explanation:
Answer:
7) m = 6
8) k = 15
9) a = -12
10) x = 1
11) n = 4
12) r = 11
Step-by-step explanation:
<h3><u>Solution</u> : </h3>
Solving all the questions step by step!
7) 1 = 6+m/12
- Hence, the value of m is 6.
8) 8 = 3 + k/3
- Hence, the value of k is 15.
9) -4(-8+a) = 80
- Hence, the value of a is -12.
10) 8(x-1) = 0
- Hence, the value of x is 1.
11) n/2 - 1 = 1
- Hence, the value of n is 4.
12) 1 = r-3/8
- Hence, the value of r is 11.
Are you in k12? cause i am and i got these questions
Answer:
Step-by-step explanation:
2x + 4x + 180
We have to do combine like terms.
2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.
All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.
Answer:
7(x+11)=9x-18
7x + 77 = 9x - 18
7x - 7x + 77 = 9x - 7x - 18
77 = 2x - 18
18 + 77 = 2x - 18 + 18
95 = 2x
95/2 = 2x/2
x = 47.5
Step-by-step explanation:
1. distribute the bracket
2. subtract 7 from both sides
3. add 18 to both sides
4. divide both sides by 2
