Orlov [11]

Answer:

<h2> The skateboard has a total cost of $90.10</h2>

Step-by-step explanation:

Givens

  • The skateboard costs $85.
  • The sales tax is 6%.

The total cost of the skateboard would be $85 plus the sales tax, like the following expression shows

85+0.06(85)=85+5.1=90.1

Therefore, the skateboard has a total cost of $90.10, which includes sales tax.

one side of a kite is 1 cm less than 4 times the length of another. if the perimeter is 38 cm, find the length of each side
lawyer [7]
We can use a system of equations to solve this.
Length 1 = x
Length 2 = y

Set up the system.
2x+2y=38
x+1=4y

Isolate the variable on one equation.
x=4y-1

Substitute that into the other equation.
2(4y-1)+2y=38

Solve.
8y-2+2y=38
10y=40
y=4

Substitute back into other equation.
x=4(4)-1=16-1=15

The lengths are 15 cm and 4 cm.

Hope this helps!
