Answer:

a) t18,10 + t18,11

b) t24,15 + t24,16

c) t13,6 +t13,7

Step-by-step explanation:

Each term of Pascal's triangle is the sum of the two terms above it in the triangle:

tn,r = t(n-1),(r-1) +t(n-1),r

a) t19, 11 = t18,10 + t18,11

b) t25,16 = t24,15 + t24,16

c) t14,7 = t13,6 +t13,7

1. Luis made a $150 bank deposit using $5 bills and $10 bills. He gave the teller a total of 24 bills. How many $10 bills were i

Answer:

6 $10 bills

Step-by-step explanation:

First you have to make a system of equations like such

5x + 10y = 150

x + y = 24

Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:

5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.

So 18 $5 bills and 6 $10 bills
