The price of the book after the sales tax would be

7.50 + 7.50 x 0.06

7.50 + 0.45

$7.95

Jay has barely enough to buy the book!

It's easy it's called Two-way tables please help
Vesnalui [34]

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

  • A = 40
  • B = 26
  • C = 14
  • D = 21
  • E = 19
  • F = 4
  • G = 17
  • H = 9
  • J = 10

Can someone help me with factoring by grouping please do step by step<br><br> problem: 3x^2+10x+7
Black_prince [1.1K]

Answer:

(3x +   7) (x +  1 )

Step-by-step explanation:

3x^2+10x+7

first : 3x² is 3x*x

(3x       ) (x        )

the sign of the constant is positive so it is either (plus *plus or minus*minus)

since the sign of the middle is plus (+10x) and 7 is prime number so it has to be (7*1)

(3x +   7) (x +  1 )

check : multiply 3x(x+1)    and 7(x+1)

3x*x +3x*1

          7*x    +1*7

____________________ add

3x²+ 10x   +7   (correct)
