Step-by-step explanation:
Hey, there!!
Let's look in your question,
Firstly Mr.Ingerson was in Ghana and bought it in 35000 cedi for a djembedrum.
At that time 1 US dollar= 7000 Cedi.
He paid 35000 cedi.
Us dollar for 35000 cedi = 35000/7000 $.
So, he had bought it in $5.
now,
At present,
The value of 1$ is 5.79 cedi.
As he bought it on same value,
5$ is equal to 5.79×5
= 28.95 cedi.
{ here, as it told that it was bought in same value its value is $5 only but, as the value of $ will be changed into 5.79}.

6.7 x -2.3 = -15.41. The hundredth value is two spaces right of the decimal. To round to the nearest hundredth, you look at the number after it in the thousandth spot. if it is less than 4 then the hundredths remains the same, if it is more than 4, then you round up the number in the hundredths spot. There is no number in the thousandth spot (0) so the answer remains -15.41

As you can see, if your polynomial or rational function has many factors, the Factor Method can be much faster.

Linear equation of plant height is h = (1/2)w + 3
Given:
Height of experimental plant = 3cm
Average growth = 0.5 cm per week
Find:
Linear equation of plant height
Computation:
Given;
h = Plant height
w = number of weeks
So,
Plant height = Height of experimental plant + (Average growth)(number of weeks)
h = 3 + (0.5)(w)
h = (1/2)w + 3
