Answer:
(i) Equation
(ii) 10 weeks
Step-by-step explanation:
The scenario is an equation and not an inequality , this is because the number of sit - ups Amelia planned to do is specific , which is 50 , had it been the question used the word like at least , at most 50 , it would have been an inequality.
The question is an example of Arithmetic sequence
From the statement ;
The first term = 5
The common difference = 5 ( since Amelia planned to add 5 more sit - ups to her training schedule each week )
The formula for the nth term of an Arithmetic sequence is given by :
= a + (n- 1 )d
= 50
a = 5
d = 5
n = ?
substituting the values , we have
50 = 5 + (n - 1 ) x 5
50 = 5 + 5n - 5
50 = 5n
n = 10
Therefore , it will take Amelia 10 weeks to reach her goal of 50 sit - ups

The number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.
<h3>What is a fraction?</h3>
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
On a poultry farm, 50 hens give 200 eggs in 2 days.
It is required to find the number of days will 20 hens require to give 400 eggs:
Let x be the number of days:
(50×2)/200 = (20x)/400
x = 10
Thus, the number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.

Answer:
in decimal form or fraction?
Step-by-step explanation:
decimal =4.7916
Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
