Answer:

75.26

Step-by-step explanation:

Most sales taxes work by not being calculated until cash in some form changes hands. So you take the discount first and then you add the sales tax on the new amount.

Take the discount first

Original cost = 79.74

Discount amount = 79.74 * 12% = 79.74 * 12/100 = 9.57

New price = 79.74 - 9.57 = 70.17

Now you are ready to add on the sales tax

70.17 * 7.25/100 = 5.09

The total is 70.17 + 5.09 = 75.26

What is the square root of 21
Andru [333]

Answer:

4.58

Step-by-step explanation:

21 is not a perfect square, but lies between the perfect squares 16 and 25.  Thus, √21 lies between √16 and √25, that is, between 4 and 5.  Since 21 is closer to 25 than to 16, √21 is closer to 5 than to 4.  A rough estimate of √21 would be 4.7.

√21 done on a calculator comes out to 4.58.

Paul was asked to use the elmination to find the solution to the system of linear equations
lbvjy [14]

Option B is correct.

Step-by-step explanation:

Paul was asked to use the elmination to find the solution to the system of linear equations

5x + 4y = 1\\-2x-8y = -26

What are the missing steps in his work below?

Let\\5x + 4y = 1\,\,eq(1)\\-2x-8y = -26\,\,eq(2)\\10x + 8y = 2 + (-2x-8y = -26) \\8x + 0y = -24 \\8x = -24 \\x = -3 \\Putting\,\,value\,\,of\,\,x\,\,in\,\,eq(1)\\5x + 4y = 1 \\5(-3) + 4y = 1\\-15 + 4y = 1 \\4y = 16\\y=4

So, the step missing is multiplying equation 1 by 2 i.e

2\times [5x + 4y = 1] \\10x + 8y = 2

So, Option B is correct.
