Subtract:4x2 + 3x – 8 from 2x2 + 7x – 5

10x-1

Step-by-step explanation:

(4×2)=8

8+3x-8

8-8+3x=3x

(2×2)=4

4-5+7x=-1+7x

3x+7x-1

10x-1

good luck

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
