He made 4 round trips to visit his grandmother.
Amount of time he spent to get to his grandmother’s = 35 minutes and extra 4-minute walk (and can be expressed as 35 + 4)
= 35 + 4
= 39
To complete a round trip, the amount of time he spent to his grandmother’s will be multiply by 2
Therefore,
= 39 x 2
= 78
Total amount of time of a round trip = 78
Amount of time he spent on a trip to her apartment and back home = 5 hours and 12 minutes
To determine that, 5 hours will be added to 12 minutes
Therefore,
Since 1 hour = 60,
Then, (5 x 60) +12
= (5 x 60) + 12
= 300 + 12
= 312
Amount of time he spent on a trip to her apartment and back home = 312
To determine how many round trip he made, the amount of time he spent on a trip to her apartment and back home (312) will be divided by the total amount of time of a round trip (78) i.e. 312 ÷ 78
= 312 ÷ 78
=
= 4
Therefore Juwan made a total of 4 round trips to his grandmother’s place.

Answer:
f(x) + g(x) = 3x
Step-by-step explanation:
The solution of x for the equation (√7)ˣ = 49ˣ⁻⁶ is,
⇒ x = 8
We have to given that,
An expression to simplify,
⇒ (√7)ˣ = 49ˣ⁻⁶
Now, We can simplify the expression for x as,
⇒ (√7)ˣ = 49ˣ⁻⁶
Since, 49 = 7² = (√7)⁴
Hence,
⇒ (√7)ˣ = (√7)⁴)ˣ⁻⁶
Apply the multiply rule in exponent,
⇒ (√7)ˣ = (√7)⁴ˣ⁻²⁴
By comparing,
⇒ x = 4x - 24
Solve for x,
⇒ x - 4x = - 24
⇒ - 3x = - 24
⇒ 3x = 24
⇒ x = 24 / 3
⇒ x = 8
Therefore, The solution of x for the equation (√7)ˣ = 49ˣ⁻⁶ is,
⇒ x = 8

Answer:
1 and 4
Step-by-step explanation:
first is the geometric series
a geometric series is a sequence of numbers whose first term is non zero and each of the succeeding terms is equal to the Prcedding term multiply by a constant number.
if a = first term
and constant number = d
then
GP is given by
a,a r , a r^2 ,a r^3 .............and so on
in first
a = 1/2
and d = 1/2
and hence it is an GP
