Hi there!
From what I know, when you multiply one number in a ratio, you must also multiply the other number by the same number. This allows for the ratio to stay the same, thus keeping it correct. If both terms were not multiplied by n, the ratio would no longer be the correct ratio.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
t = 1, but please check to see if I correctly interpreted your formatting.
Step-by-step explanation:
The format of the question is too confusing.
I'll assume this is the equation to be solved:
<u>16−2t=t+9+4t</u>
<u></u>
16−2t=t+9+4t
16-9 = t + 2t + 4t
7 = 7t
t = 1
12s - 20 <u><</u> 50 - 3s - 25
12s - 20 <u><</u> 50 - 3s - 25
<u>+3s +3s</u>
15s - 20 <u><</u> 50 - 25
<u> + 20 + 20 </u>
15s <u>< </u> 70 - 25
15s <u><</u> 45
<u>÷ 15 ÷15</u>
s <u><</u> 3
The value of s is less than or equal to 3. So s can be 3, 2, 1, 0, and negative numbers.
s = 3 ⇒ 12(3) - 20 <u><</u> 50 - 3(3) - 25 ; 36 - 20 <u><</u> 50 - 9 - 25 ; 16 <u><</u> 16
s = 2 ⇒ 12(2) - 20 <u><</u> 50 - 3(2) - 25 ; 24 - 20 <u><</u> 50 - 6 - 25 ; 4 <u><</u> 19
Answer - c </= 4 or c >/= -3
2c - 1 </ 7
2c - 1 + 1 </= 7 +1
2c </= 8
2c/2 </= 8/2
c </= 4
2c - 1 >/= - 7
2c - 1 + 1 >/= -7 + 1
2c >/= -6
2c/2 >/= -6/2
c >/= -3
