Answer:
4.4
years corresponding to 4 years and 5 months (more or less)
Step-by-step explanation:
Let us set
P
=
25
we get:
25
=
8
e
0.26
t
rearrange:
e
0.26
t
=
25
8
take the natural log of both sides:
ln
[
e
0.26
t
]
=
ln
[
25
8
]
simplify:
0.26
t
=
ln
[
25
8
]
t
=
1
0.26
ln
[
25
8
]
=
4.38
≈
4.4
years corresponding to 4 years and 5 months (more or less)
Answer:
x = 7
Step-by-step explanation:
We are told one quarter of x is equal to 7 , then the equation is

x = 28
Answer:
When multiply a number by another number and get that number.
Answer:
2 solutions
Step-by-step explanation:
Easy trick: The number of solutions an equation has is found by the highest degree of the polynomial which in this situation, 2.
3x + 55 = 2(6x + 5)
3x + 55 = 12x + 10
9x = 45
x = 5
length of mid-segment = 6(5) + 5 = 35
