Step-by-step explanation:
sum of two Number the second Number is 5x the first so....
45+5=10
so five times equal to 5+5=10
so the first is 45 second Number is 10
$50 - $19 = $31
$31 - $5.50 = $25.50

Answer:
Step-by-step explanation:
we know that
1 mile=5,280 feet
we have that
Elena ran 2-1/2 miles
<em>Convert mixed number to an improper fraction</em>
Convert miles to feet
40 = 4 * 10
sqrt40 = sqrt2 * sqrt10
= 2 sqrt10
(3 + 6i)(3 + 7i)
FOIL: First, Outside, Inside, and Last
3 x 3 = 9
3 x 7i = 21i
6i x 3 = 18i
6i x 71= 42i
9 + 21I + 18I + 42I = 9 + 81I
a = 9
B = 81I
