Answer:
The solution would be (0, 5)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
4x + 4y = 20
4x + 4(x + 5) = 20
4x + 4x + 20 = 20
8x + 20 = 20
8x = 0
x = 0
Now that we have the value of x, we can find the value of y.
y = x + 5
y = 0 + 5
y = 5
Answer:
D)5/11
Step-by-step explanation:
So yeah there's 22 balls in total!
Then for the red balls, there are the balls numbered evenly: 6, 8, 10, 12, 14. So there's 5 even balls for red.
Then for the green balls: 8, 10, 12, 14, 16, there are also 5!
5+5=10
10/22
=5/11
The answer is D!

Answer:
Price for Senior Citizen = $7.61
Percent of the regular price = 85% off original
Step-by-step explanation:
Regular Price is $8.95
Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.
To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.
15% = 15/100 = 0.15
Fifteen Percent of 8.95 is:
0.15 * 8.95 = $1.3425
Senior Citizen Price = 8.95 - 1.3425 = $7.6075
Rounded to nearest cent = $7.61
How much is this as a percentage of original?
Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price
