X=2
I’m still gonna explain lol
6(2)=12+4=16/2=8
Answer:
As described in picture:
RPS = 5x + 34
QPR = 8x + 15
RPS +QPR = QPS = 88
=>5x + 34 + 8x + 15 = 88
=> 13x + 49 = 88
=> 13x = 39
=> x = 3
=> RPS = 5 x 3 + 34 = 15 + 34 = 49 deg
Hope this helps!

Answer:
Step-by-step explanation:
We get to use the simple version of the half life equation:
where N is the amount of radioactive element left after a specific number of years,
N0 is the initial amount of the element,
t is the number of years (our unknown), and
H is the Half life of the element. For us,
N is 61
N0 is 70,
t is unknown,
H is 24 years. Filling in:
. We begin by dividing both sides by 70 to get:
and then take the natural log of both sides:
which allows us to bring down the exponent to the front on the right side:
. We divide both sides by ln(.5) to get:
and then multiply both sides by 24 to get:
t = 4.8 years
