Answer:
p = 11.2
Step-by-step explanation:
2.6(5.5p - 12.4) = 127.92
14.3p - 32.24 = 127.92
Add 32.24 to both sides
14.3p = 127.92 + 32.24
14.3p = 160.16
Divide both sides by 14.3 (the coefficient of p)
p = 11.2

Answer:
Four consecutive numbers are 2, 6, 10 and 14
Step-by-step explanation:
15(a² - 9d²) = 7(a² - d²)
15a² - 135d² = 7a² - 7d²
15a² - 7a² = 135d² - 7d²
8a² = 128d²
Putting the value of a = 8 in above we get.
8(8)² = 128d²
128d² = 512
d² = 512/128
d² = 4
d = 2
So, the four consecutive numbers are
8 - (3*2)
8 - 6 = 2
8 - 2 = 6
8 + 2 = 10
8 + (3*2)
8 + 6 = 14
