Answer:
Step-by-step Solution:
<u>Isolate the variable x to get the answer.</u>
- x − 2/5 = −1
- => x = -1 + 2/5
- => x = -1 + 0.4
- => x = -0.6
Hence, the value of x is -0.6.
The number of situps form an AP with first term (a) = 17 and common difference (d) = 4
Tn = a + (n - 1)d
T12 = 17 + (12 - 1) x 4 = 17 + 11(4) = 17 + 44 = 61
Therefore, she will do 61 situps on day 12.
