Answer:
sales tax: $10.49
Total: sales tax+charges = $160.29
Step-by-step explanation:
to find out sales tax, follow formula
Tax $ = OG $ x Tax%
*usually easier to convert % to decimal if calculator does not have % option*... to convert % to decimal.. move two decimals to left and vice verse decimal to % will be two decimals to right*
ex. 7% = .07
Answer:
6.79
Or 6.80
Step-by-step explanation:
2.09×3.25= 6.79
I mean a real easy answer is 1/2
Answer:
$2.50 can be your constant because you will have to pay it once in order to bowl. $2.25 can be the coefficient of the variable. You can form the equation now. y is total price while x is how many games you can bowl.
Now that you have the equation, you can solve. Knowing that you have $9.25, just plug in that value in the y
Now, just simply solve for x and you will find the answer to the second part of the question. You will get x=3
Step-by-step explanation:
X+7y=0 (a)
2x-8y=22 (b)
1st write te 2 equation in terms of x
(a) x+7y=0 , then x= -7y
(b) 2x-8y=22 → 2x = 22 + 8y and x = 22/2 +8y/2 OR x = 11 + 4y
x = 11+4y and x = -7y Then 11 + 4y = -7y
Now we can extract the value of y:
11+4y = -7y
1st Add +7y to each side →11+4y+7y = -7y + 7y
11+ 11y = 0 . Now subtract 11 from both sides :→11+11y -11 = 0-11
11y = -11 and y = - 1
To find the value of x, replace the value of y (= - 1) in any of the given equation and you will find x = 7
