Combine like terms.
Like terms have the same variables.
4.2v and -6.5v are like terms. They can be combined.

4.2v - 5 - 6.5v =

= 4.2v - 6.5v - 5

= -2.3v - 5

The value of a professional basketball player's autograph rose 30% in the last year. It is now worth $273.00. What was it worth
serg [7]
$210
because if it rose 30%, it's now 130% of what is used to be
or (what it used to be) ×1.3
so do the reverse and divide the new cost by 1.3
so 273÷1.3 which is 210

I need help with this problem
alexandr402 [8]

Answer:

4*x^4*y^22

Step-by-step explanation:

Your goal here is to REDUCE the given expression to simplest terms.

One way in which to approach this problem would be to rewrite (2x^2y^10)^3 as:  (2x^2*y^8)*y^2*(2x^2*y^10)^2.

Dividing this rewritten expression by 2x^2*y^8 results in:

y^2(2x^2*y^10)^2.

We now need to raise (2x^2*y^10) to the power 2.  Doing this, we get:

4x^4*y^20.

Multiply this by y^2 (see above):

y^2*4x^4*y^20

The first factor is 4:  4y^2*x^4*y^20.  This is followed by the product of y^2 and y^20:                   4*y^22*x^4

Finally, this should be re-written as

                                    4*x^4*y^22

Another way of doing this problem would involve expanding the numerator fully and then cancelling out like factors:

8*x^6*y^30      4*x^4*y^22

----------------- = ------------------ = 4*x^4*y^22

  2x^2y^8                  1

alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. which expression represents the total amount that alexi
Alexeev081 [22]
He is leaving 20% tip of the bill of $58

20% extra

So total amount = 100% + 20% = 120%

120% of 58

(120/100) * 58

1.2 * 58

= 69.6

So total amount Alexi needs to pay = $69.60
