5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1
5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4
solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5
x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9
solution is : (9,5)
Hey there,
Your question states: <span>A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. The total bill was $94.75. Write and solve an equation to find the price of each shrub.
So, I will do 94.75 minus 11.50 because he bought nice scrubs so that would be 83.25.
I will do 83.25 divided by 9 because that's the number that person bought, each scrub will end up to be 9.25.
Hope this helps.

Answer:
14
Step-by-step explanation:
Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.
and for extra just in case.
Mean=16.222
the mean= the average of the data set
Mode is 13,14
The mode is the number that appears the most in a data set and 13 and 14 appear twice.
Your range is=13
Range is the highest number subtracting the lowest number so 24 -11 which =13
Minimum is 11 because the minimum is the lowest number in data set..
Maximum is 24
Maximum is the highest number in the data set.
I hope this helps have a awesome day:)

Answer: $611</h3>
Work Shown:
30% of 470 = 0.30*470 = 141
The value goes up by $141, so the answer would be 470+141 = $611
A slight shortcut would be to say
1.30*470 = 611
This works because 1.30 = 1 + 0.30 = 100% + 30%
