Answer:
12
Step-by-step explanation:
the total number of bills equals 12 f + t = 12 there are five times as many tens is 5+ t = 5 f substitute to eliminate t f + 5 f = 12 solve the number of fives f equals to remember there are five times as many tens t equals 10 check 2 + 10 = 12
Assuming i=√-1
treat i as a variable
A-M+S-P=
(4-3i)-(-4+i)+(i)-(2)=
4-3i+4-i+i-2=
4+4-2-3i-i+i=
6-3i

Step-by-step explanation:
Answer:
17 - i
Step-by-step explanation:
<u>Step 1: FOIL out</u>
(1 - 3i)(2 + 5i)
(2) + (1 * 5i) + (-3i * 2) + (-3i * 5i)
2 + 5i - 6i - 15i^2
2 - i + 15
<em>17 - i</em>
