Step-by-step explanation:
Answer:
1/2x-7
Step-by-step explanation:
Add 3/8x and 1/8x to get 4/8x which is the same as 1/2xThen add the integers: -2 + -5 = -7.

The simple interest equation that represent the situation is A = t/5
<h3>What is simple interest?</h3>
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest. For example, when a person takes a loan of 500 dollars, at a rate of 10 per annum for two years, the person's interest for two years will be S.I. on the borrowed money.
Principal(P) borrowed = $2
Rate(R) in percentage = 10
time in years = t
Simple interest(A) = P X R X t / 100
A = 2 X 10 X t/ 100
After reducing 20/100 to the lowest term
A = t/5
In conclusion the simple interest(A) = t/5

Answer: the 7th person will get 3.125 pieces of gum.
Step-by-step explanation:
The first student gets one-half and each student gets half of what's left each time. This means that number of pieces of gum that each student gets is reducing in geometric progression. The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = 200
r = 0.5
n = 7
The 7th term, T7 is
T7 = 200 × 0.5^(7 - 1)
T7 = 200 × 0.5^6
T7 = 3.125
