Hi there! The answer is k = 16
To find our answer we only need to collect the terms. In other words: we need to subtract all the values of k.
Example:

If you don't get this, you can try to understand it by using a story: in a cage, there are 18 koalas, 11 of them leave. How many are left?
18 koalas - 11 koalas = 7 koalas
18 k - 11 k = 7 k
Now we keep doing this again and again to find our final answer:

~Hope this helps you!
Answer:
40,000,000 (40 million)
Step-by-step explanation:
100,000,000 - 60,000,000 = 40,000,000
same as (without the zeros) 10 - 6 = 4
40x18=720 for the whole thing
720-320= 400 for the deck
Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,<u>44</u>
Y can equal: 1.5,3,4.5,<u>6</u>,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.
Answer:
f(60)=280
Step-by-step explanation:
f(x)=0.4x²-36x+1,000
x=60→f(60)=0.4(60)²-36(60)+1,000
f(60)=0.4(3,600)-2,160+1,000
f(60)=1,440-2,160+1,000
f(60)=280
This mean that a driver of 60 years old will have 280 accidents per 50 million miles driven.
