That means there would be 28 in California and still 12 in Nevada or if California takes from Nevada it would be California 28 and Nevada 2
Answer:
Step-by-step explanation:
We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.
5g +4b = 60 . . . . . Sylvester's expense
3g +6b = 45 . . . . . Lin's expense
Dividing the second equation by 3 gives ...
g +2b = 15 ⇒ 2b = 15 -g
Substituting into the first equation, we have ...
5g +2(2b) = 60
5g +2(15 -g) = 60 . . . . . substitute for 2b
3g = 30 . . . . . . . . . subtract 30, collect terms
g = 10 . . . . . . . divide by 3
__
2b = 15 -10 = 5 . . . . use the value of g to find b
b = 2.5 . . . . . . . . divide by 2
Mini golf costs $10 per round; batting cages cost $2.50 per turn.

Answer:
Graph y = 2x
Step-by-step explanation:
First, let's get the equation into standard form. Distribute the 2 on the right.
![y-4=2x-4](https://tex.z-dn.net/?f=y-4%3D2x-4)
Next, we want the variable "y" to be alone, so we at 4 to both sides.
![y-4+(4)=2x-4+(4)\\\\y=2x](https://tex.z-dn.net/?f=y-4%2B%284%29%3D2x-4%2B%284%29%5C%5C%5C%5Cy%3D2x)
That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.
We do, however, have a slope, which can be thought of as
or rise over run. To represent this, we can rewrite our slope as:
![y=\frac{2}{1}x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B1%7Dx)
Meaning in each interval, the line goes up by 2 units, and moves forward by 1.
Answer:
x = 8; y = 29
Step-by-step explanation:
In a parallelogram, opposite angles are congruent.
8x = 7x + 8
x = 8
4y = y + 87
3y = 87
y = 29
