He has a total of $58.19.
1 day = $2.74
58.19/2.74
21.24
You can't have 21.2 days, so you need to round down to 21.
Jim can buy lunch for 21 days before he runs out of money on his account.
Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8
The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.
After doing this, we realize that only -1 works, so the answer is x=-1
Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)
Best wishes:)
Answer:
4/5 mile
Step-by-step explanation:
14/15 - 2/15 = 12/15 or 4/5
Based on our conversation above, we can then easily find the missing x-coordinate. If the equation for line BC is y = 6*x - 11 and we know that the y-coordinate is 13, then
13 = 6*x - 11
24 = 6*x
4 = x
The x-coordinate is 4.
