Answer:
v= p/l
Step-by-step explanation:
divide by l on both sides to get v by itself, and you have your answer.
On substituting x= 9 in the above equation,
y= 9-5= 4
and, the y coordinate is also same i.e. 4
Yes.
It satisfies the equation.
I hope this helps you...
Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y
From person A's purchase, we get
12x + 7y = 15.5; equation A
And from person B's purchase,
6x + 11y = 11.5; equation B
Let us multiply equation B by 2 and subtracting equation A from it, we will get
12x + 22y - 12x - 7y = 23 - 15.5,
=> 15y = 7.5
or, y = 0.5
Substituting value of y in equation A, we can find x
12x + 7*0.5 = 15.5
=> x = (15.5 - 3.5)/12
or, x = 1
Therefore, cost of granola bar is $1, and that of yogurt is $0.5
When you add something, you gain more of it. Therefore, it should be positive 2
