Answer:
x = 2
y = -1
Step-by-step explanation:
Since it gives you the value of y already, just plug that into the equation, like so:
y = 4x - 9
x - 3 = 4x - 9
<em><u>Subtract the x from both sides:</u></em>
x - 3 = 4x - 9
-x - x
__________
-3 = 3x - 9
<em><u>Then, add 9 to both sides:</u></em>
-3 = 3x - 9
+9 + 9
________
6 = 3x
<em><u>Divide both sides by 3:</u></em>
2 = x
<em><u>Now plug in x for y:</u></em>
y = x - 3
y = 2 - 3
y = -1
Answer:
Step-by-step explanation:
18 stickers------1 page
212 stickers------x pages
For this we can write equation like that:
18*X = 212*1
18x=212
X=11.7777= It means Fiona needs 12 pages for using all these stickes.
The average is 80*
80* + 80*=160 divided by 2 is 80*
The mean is 30,000
The standard deviation is 10,893.42
