First, add 139+184=323.
Then multiply 170 to 3 to get the total number of points he must get to achieve that average.
170 multiplied to 3 gives you 510.
Then subtract 500- (139+184)= 187. This is the number of points Ben must get in his third game to have an average of 170

Answer:

187

Step-by-step explanation:

Were gonna start by writing an equation (139+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 187. Hope this helps.

Answer:

i dont know how your teacher teaches it but in the first question take away the y after the 25. number 2 the start equation would be 55=2x+25 then you would subtract 25 from each side to get 30=2x, the divide by to to get x=15 or she made 15 calls. number 3 is correct.

i hope this helps

Help pls do allll 6 questions... with steps
BaLLatris [955]
You just want to simplify right?!

45. (a^2b^3)(ab)^-2
= (a^2b^3)(a^-2b^-2)
= b
46. (-3x^3y)^2(4xy^2)
= (-9x^6y^2)(4xy^2)
= -36x^7y^4
47. 3c^2d(2c^3d^5) / 15c^4d^2
= 6c^5d^6 / 15c^4d^2
= 2/5c1/4x^4
48. -10g^6h^9(g^2h^3) / 30g^3h^3
= -10g^8h^12 / 30g^3h^3
= -1/3g^5h^9
49. 5x^4y^2(2x^5y^6) / 20x^3y^5
= 10x^9y^8 / 20x^3y^5
= 1/2x^6 1/3y^3
50. -12n^7p^5(n^2p^4) / 36n^6p^7
= -12n^9p^9 / 36n^6p^7
= -1/3n^3p^2

(Sorry it’s messy it’d look better if my phone could actually put the numbers to the power)

2x + 3 = 0  or  2x - 1 = 0

x = -3/2   or x = 1/2

Y=7(15+x) solve for x m888888888888
horsena [70]
         Y = 7(15 + x)   Use the Distributive Property
         Y = 105 + x     Subtract 105 from both sides
Y - 105 = x               Switch the sides to make it easier to read
          x = Y - 105
