The price of a calculator is 12.50 the sales tax is 7.5 How much will you pay for the calculator

Vikentia [17]

Sales tax = 7.5%

7.5% of 12.50 = (7.5/100) * 12.5 = 0.075* 12.5 = 0.9375

tax = 0.9

Total pay = price + tax = 12.5 + 0.9375 = 13.4375

Total pay ≈ 13.44

Hope this solves it.

Solve using the elimination method x + 5y = 26 - X+ 7y = 22

S_A_V [24]

Answer:

$x=6\\y=4$

Step-by-step explanation:

Elimination method:

$x+5y=26$

$-x+7y=22$

Add these equations to eliminate x:

$12y=48$

Then solve $12y=48$ for y:

$12y=48$

$y=48/12$

$y=4$

Write down an original equation:

$x+5y=26$

Substitute 4 for y in $x+5y=26$ :

$x+5(4)=26$

$x+20=26$

$x=26-20$

$x=6$

{ $x=6$ and $y=4$ } ⇒ $(6,4)$

hope this helps...

$(6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36$

Step-by-step explanation:

Even if I don't know the options I can give all the option that will be right for expending this. Just look at each step and see which one is one of the options.
