Prove if a and b are integers, prove that if a is even and b is even then a+b is even

jeka57 [31]

Answer:

Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that $a=2k$ and $b=2m$ .

Then,

$a+b=2k+2m=2(k+m)=2n$

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.

The sales tax for an item was $24.50 and it cost $490 before tax.

Ymorist [56]

The sales tax rate is 5%.

Step-by-step explanation:

Given,

Sales tax for an item = $24.50

Cost of item before tax = $490

Sales tax rate = $\frac{Sales\ tax}{Cost\ of\ item}*100\\$

$Sales\ tax\ rate=\frac{24.50}{490}*100\\\\Sales\ tax\ rate=\frac{2450}{490}\\\\Sales\ tax\ rate=5\%$

The sales tax rate is 5%.
