To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get th

e variable by itself. The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side. 5 + y = 7

Answer:

y = 2

Step-by-step explanation:

Given

5 + y = 7

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

5 + y = 7

-5 + 5 + y = 7 - 5

0 + y = 2

y = 2

A certain element has a half life of 2.5 billion years. a. You find a rock containing a mixture of the element and lead. You det
sashaice [31]

Answer:

Step-by-step explanation:

For a first order decay, fraction remaining = 0.5n where n = number of half lives elapsed.

fraction remaining = 55% = 0.55

0.55 = 0.5n

log 0.55 = n log 0.5

-0.2596 = -0.301 n

n = 0.8625 = # of half lives elapsed

0.8625 half lives x 2.5 billion years/half live = 2.16 billion years have elapsed = age of the rock

b)  0.15 = 0.5n

log 0.15 = n log 0.5

-0.824 = -0.301 n

n = 2.74 half lives

2.5 billion years/half life x 2.74 half lives = 6.85 billion years = age of rock
