The answer would be 48 because....
First, you would multiply 80 and .40 (changed the percentage to decimal) which is 32
Then, subtract 80 and 32 to get 48
SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by

Substituting these values into the equation above we have

Hence, the answer is 42, option B
Answer:
i) x^2=y+5
ii) 2x-6y=10
Step-by-step explanation:
x represents the first number and
y represents the second number
Relationship is given as
i) The square of the first number is equal to the sum of the second number and 5
x^2=y+5
ii) The difference of twice the first number and 6 times the second number is 10.
2x-6y=10
