Answer:
(5,-2)
Step-by-step explanation:
9x+5y=35
2x+5y=0
Multiply the second equation by -1
-1 (2x+5y) = 0*-1
-2x-5y = 0
Add the first equation and the modified second equation
9x+5y=35
-2x-5y = 0
-------------------
7x = 35
Divide by 7
7x/7 = 35/7
x = 5
Now we need to find y
2x+5y = 0
Substituting in x
2(5) +5y = 0
10 +5y = 0
Subtract 10
10-10 +5y = -10
5y = -10
Divide by 5
5y/5 = -10/5
y = -2
(5,-2)
Answer:
Step-by-step explanation:
Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.
Answer is point P.
(-3, 6)
Point L represents the given coordinates.
Point P represents the given coordinates.
Since, x and y coordinates are positive, point will lie in the 1st quadrant.
Point Q represents the given coordinates.
Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.
Point R represents the given coordinates.
8:4 Is the ratio of the number of lines with cashiers to the number of self-checkout lines.
This is a simple application of english system conversions. I'm afraid that's all there is to it, you're just going to have to commit these to memory.
That said, I shall walk you through the problem. This one is fairly easy.
We know that in one pint there are two cups. As such, in two pints there are four cups, and in three pints there are six cups.
Therefore, there are <u>6 cups in 3 pints</u>.
Hope this helps :)
16 miles because first you have to subtract your flat rate of $2 from $10, which will leave you left with $8. If it’s $0.50 per mile then divide that by the amount of money you have remaining after the flat rate deduction (8/0.50). After dividing you will find that you have enough money to travel 16 miles.
