Answer: -7
Form your equation. Let x be the number.
6x + 10 = 4x - 4
Solve.
6x + 10 = 4x - 4 Subtract 4x from both sides
2x + 10 = -4 Subtract 10 from both sides
2x = -14 Divide by 2 to both sides
x = -7 Answer!

Step-by-step explanation:
This is the concept of exponential growth;
the formula for obtaining the number of bacteria at time t in future is:
f(t)=ae^(kt)
where;
f(t)=population in future
a=initial population
k=constant of proportionality.
suppose the initial population was x, when the population doubles it will be 2x at a future time t.
k=0.027
thus substituting the above in our formula we get:
2x=xe^(0.027t)
solving for t we get:
2=e^(0.027t)
introducing the log function we get:
ln2=0.027t
thus;
t=(ln2)/0.027
=25.67
therefore;
t=25.67 hours
Answer:
Emily gets 35 marbles and Asif gets 7 marbles.
Step-by-step explanation:
let 5x and x be marbles Emily and Asif get.
5x + x = 42
or, 6x = 42
or, x= 7
5x = 5×7=35
x =7
