Brian wants to purchase a car wash "package" from his local car wash. He can either get unlimited car washes for a month for $35

with no additional charges. Or, he can buy a discount package, where he pays $22 for the month plus $1.50 per car wash. He wants to know how many car washes he would need to get in order to make the $35 deal a better choice.
y=22x+1.5 Substitute 35 for x: y=22(35)+1.5; y=771.5, which means it would take 772
car washes for the plans to be worth the same amount.

y=1.5x+22 Substitute 35 for y: 35=1.5x+22; y≈8.7, which means at 9 car washes, the unlimited package at $35
would be cheaper.

y=22x+1.5 Substitute 35 for y: 35=22x+1.5; y≈1.5, which means at 2 car washes, the unlimited package at $35
would be cheaper.

y=1.5x+22 Substitute 35 for x: y=1.5(35)+22; x=74.5, which means the discount package is cheaper unless Brian gets 75 car washes.

Answer:

6√2

Step-by-step explanation:

So the diagonal of a square is equal to √2 times the length of the side of the square. Working backwards that would mean: 12/√2 = side of square

this means that the side of the square is 6√2

The side of the square is also the diameter of the circle.

I'm not sure this was the type of formula you're looking for but I hope it helped!

What is 2x-(x-2)=-2-(x-1)​
bezimeni [28]
Distribute first so
2x-x+2=2-x+1
Combine like terms so
x+2=3-x
Get terms on the same side so
2x+2=3
Subtract 2
2x=1
Divide
X=1/2 or .5
