Answer:

Step-by-step explanation:

x³ = 8

Cuberoot of x³ = cuberoot of 8

x = 2

y² = 25

√y² = √25

y = 5

2 + 5 = 7

Answer:

15.2

Step-by-step explanation:

x^3 = 8

x = 8/3

x = 2.7

y^2 = 25

y = 25/2

y = 12.5

x+y = 2.7 + 12.5 = 15.2

The sum of the first three terms of a geometric sequence of positive integers is equal to seven times the first term, and the su

attashe74 [19]

The first 3 terms are a, ar and ar^2
so a + ar + ar^2 = 7a

a + ar + ar^2 + ar^3 = 45
7a + ar^3 = 45
a(7 + r^3) = 45
a = 45/(7 + r^3)
Because we know the sequence are positive integers r must be a natural number.
(7 + r^3) is a factor of 45 [ie 1, 3, 5, 9, 15, 45]
so r = 2 because 7 + 2^3 = 15 is the only factor possible
a = 45/15 = 3

Answer:

$\large\boxed{p=1}$

Step-by-step explanation:

$\dfrac{2}{5}+p=\dfrac{4}{5}+\dfrac{3}{5}p\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{2}{5\!\!\!\!\diagup_1}+5p=5\!\!\!\!\diagup^1\cdot\dfrac{4}{5\!\!\!\!\diagup_1}+5\!\!\!\!\diagup^1\cdot\dfrac{3}{5\!\!\!\!\diagup_1}p\\\\2+5p=4+3p\qquad\text{subtract 2 from both sides}\\\\5p=2+3p\qquad\text{subtract 3p from both sides}\\\\2p=2\qquad\text{divide both sides by 2}\\\\p=1$
