X=2, y=4. Easiest way to solve this problem is to have the y's cancel out. Multiply the first equation by -2 and the bottom by 3. You'd want to do one as a negative number since both are already negative; making one positive makes everything easier.
Here you should find x = 2.
Then plug it back into one of the equations to solve for y.
y = 4. Check you work by plugging it back in.
This is fairly easy.
60x30=1800
Just add up the zeros from both numbers and do 6x3.
So therefore there will be 18 hundreds sections since there is nothing on the tens digit and nothing on the ones digit.
Hope this helps!
Answer: 0.1630
Step-by-step explanation:
Number of quarters = 10
Number of dimes = 6
Number of nickels = 8
Total number = 10+6+8 = 24
Probability of choosing the first quarter will be: = Number of quarters/Total number of money
= 10/24 = 5/12
Since a quarter has been selected, the total number will reduce to 23 the next time a quarter is choosing and the number of quarters will now be 9. Therefore, the probability of choosing the second quarter will be: = 9/23
Therefore, the probability that two quarters are chosen random from the jar will be:
= 5/12 × 9/23
= 45/276
= 0.1630
Answer: it never changes.
