Ok let me explain it to you like this:
Let the price for one egg be x and the price for one toast be y Then: <span><span>3 = </span><span><span>2x+1y,
</span><span>1.8 = 1x+1y.</span></span></span><span>When we substract, we get x = 1.2 and y = 0.6, so the price for an egg is $1.20 and the price for a toast is $0.60.
</span>Hope this is helpful
Answer:
x=1 y=-5 x=3 y=-9 x=0 =-3

Answer:
The probability that the product of 2 numbers that Drake rolls is less than = 
Step-by-step explanation:
Drake rolls two fair number cubes i.e. 6 sided die. He then multiplies the numbers shown on each die. The result of the all possible products are shown in the given table. The given table is missing a 1 in the first row. The complete first row will be:
1 2 3 4 5 6
The total number of possible outcomes are 36. We have to find the probability that product of two numbers that Drake rolled is less than 10. For this, first we need to count the number of outcomes that are less than 10. From the table we can see that the number of possible outcomes that are less than 10 are = 17
Probability is defined as the ratio of favorable outcomes to the total number of outcomes. Here, total outcomes are 36 and favorable outcomes are 17.
So,
The probability that the product of 2 numbers that Drake rolls is less than =

Answer:
3.63 * 10^19
Step-by-step explanation:
Given that :
Number of choices to select = 12
Category available :
Blues - 14
Country - 25
Disco - 21
To select an equal number of song for each category ; then 4 songs will be selected from each :
Using combination :
(14C4 * 25C4 * 21C4)
Since the order matters for the 12 selected songs ; it thus requires 12 permutation
Thus ;
(14C4 * 25C4 * 21C4) * 12!
nCr = n! / (n-r)!r!
Using calculator;
14C4 = 1001 ;
25C4 = 12650
21C4 = 5985
12! = 479001600
Hence,
(1001 * 12650 * 5985) * 479001600
= 36301596217286400000
=3.63 * 10^19
