The expression is
5x + 5y
We are to prove that it is an odd integer when x and y are integers of opposite parity
First, we can assume
x = 2a (even)
y = 2b + 1(odd)
subsituting
10(a + b) + 5
5 [(2(a + b) + 1]
The term
2(a + b) + 1 is odd and the result of an odd number multiplied by an odd number is odd
Answer:
x < 3
Step-by-step explanation:
5x+7x<36
12x<36
Divide both sides by 12
x<3
Answer:
75%
Convert 3/4 to a percent. Begin by converting the fraction 3/4 into decimal. Multiply the decimal by 100 and write the result with the percentage sign: 0.75 × 100 = 75%.
Step-by-step explanation:
Step-by-step explanation:
Simple interest =P (1+. R )^n
/100
Where P is the amount
R is rate (%)
n is number of years
So if you are given months your divide ➗ the number of months by 12 years
2710 *(1+ [ 3.8/100])^3/12
