Answer:
b) (-3 + 5i)(1) = -3 + 5i
Step-by-step explanation:
First let's see what a multiplicative identity.
The <em>multiplicative identity property </em>states that any time you multiply a number by 1, the result is the original number.
Therefore, 1 is the multiplicative identity.
For instance, 3 * 1 = 3
Hence, according the property
(-3 + 5t)(1) = -3 + 5i states the multiplicative identity.
Hope you will understand the concept.
Thank you.
Unit cost is what the drink would cost per fl. oz.
To find the unit cost, divide the total cost by the number of fl. oz.
$2.00 / 16 fl. oz. = $0.125 / fl. oz.
Make the fractions improper to multiply.2 1/5 becomes 11/5 and 1 3/4 becomes 7/4. multiply the numerators then multiply the denominators. you get 77/20, which is simplest form. don't let teachers feed you that bs about it having to be a mixed number. an improper fraction is way more useful.

Answer:
<h2>Jordan age = 31 years</h2><h2>Anna age = 19 years</h2>
<u>Step-by-step explanation:</u>
let Jordan age be <u>X</u> & Anna age be <u>Y</u>
so,
Jordan is 12 years older than Anna.
x = y + 12 ......... (1)
The sum of their ages is 50.
x + y = 50 ........ (2)
putting value of x from (1) into (2)
x + y = 50
(y + 12) + y = 50
2y + 12 = 50
2y = 50 - 12
2y = 38
y = 38÷2
y = 19
putting value of y in (2)
x + y = 50
x + 19 = 50
x = 50 - 19
x = 31
so,
Jordan age = 31 years
Anna age = 19 years
