Can someone please answer this question please answer it correctly and please show work please help me I need it
JulsSmile [24]

Answer:

B

Step-by-step explanation:

We'll use Natasha's location as 0 on a number line. To the left of her, 51/20 would be negative and 25/4 would be positive.

To find how far apart the dogs are, we would need to add the absolute value of each number:

|-51/20| + |25/4| however, this can also be rewritten as:

25/4 - (-51/20)

Later 7 students joined group 2 (41 students)and one student left to join group 1. (44 students) Now 20 students play trombone a
Anit [1.1K]

48 students in group 2

43 students in group 1

So in total there are 91 students

7 students play the trump

And 20 play the trombone

Therefore it is known that 27 students play those two instruments in total

Because of this, Subtract 27 from 91 to get the num of students who doesn't play those instruments.

David is buying a cheese wheel priced at \$650$650dollar sign, 650 before tax. The store charges 8\%8%8, percent sales tax.
lozanna [386]

Answer:

$702

Step-by-step explanation:

To find the total price of the cheese wheel that David is buying, we need to multiply the original cost to sales tax first.

Original Cost = $650

Sales Tax Percentage= 8% or 0.08

Now let's solve for how much the sales tax is.

Sales Tax = 0.08 x 650

Sales Tax = $52

Now to get the price including the tax, we simple add the original cost to the sales tax.

Total Price = $650 + $52

Total Price = $702

So the cheese wheel that David bought is $702 with tax included.
