Multiplying both sides of this equation by 3, to eliminate the fraction, we get:
9 + m = 6.
Next, we subtract 9 from both sides to isolate m: m = 6 - 9 = -3
Then m = -3.
Check: Subst. -3 for m in this equation:
9 - 3 6
------- = ------ = 2 (as expected). Thus, m = -3 is correct.
3 3
Problem #10:
4n - 9 = -9 Add 9 to both sides: 4n = -9 + 9 = 0.
Divide both sides by 4: n = 0.
Check: Substitute 0 for n: 4(0) - 9 = -9 is true.
Answer:
Assuming you mistyped and meant, "wich is the smallest number with 30 as a divisor? Please put procedure" Your answer would be 60.
Step-by-step explanation:
60/30=20. The first part of my answer is there because there is no way you didn't mistype.
<span>Desargues Pythagoras Pappus is the answer i think</span>
For the first one the number 5 goes into 15 3 times and you need to do the same to both top and bottom so to get the answer you need to times 9 by 3. Which gives you 27 so the answer for the first one would be
15:27.
For the second question you would do exactly the same as the first divide 35 by 7 which gives you 5 you then times 5 by 5. Which gives you 25. So the answer for the second would be 25/35.
15/27
25/35
The answer would be 10.
6 + 5 = 11
11 x 9 = 99
This means 9(6+5) = 99
99 - 89 = 10
