4/5 and 40/50 are both equivalent
Answer:
13, 15, 17
Step-by-step explanation:
Gọi 3 STN lẻ cần tìm là a, a+2, a+4 (a thuộc N*)
Theo đề bài ta có:
(a + 2)(a + 4) - 177 = 6a
=> a^2 + 4a + 2a + 8 = 6a + 177
=> a^2 + 6a + 8 = 6a + 177
=> a^2 + 6a - 6a = 177 - 8 (chuyển vế)
=> a^2 = 169 = 13^2
=> a = 13
=> a+2 = 15, a+4 = 17
Vậy 3 STN lẻ cần tìm là 13, 15, 17
Since T is the midpoint of PQ, this means that PT and TQ must be equal to each other. Make them equal to each other in an equation.
PT = TQ
4x + 2 = 7x - 7
- Subtract 2 from both sides.
4x = 7x - 9
- Subtract 7x from both sides.
-3x = -9
<u>x = 3</u>
- Now substitute 3 for x into PT.
PT = 4(3) + 2
<h3>PT = 14</h3>
