The price of a television was reduced from 250 to 200 .by what percentage was the price of the television reduced

5x+2x=49

7x=49

x=7. 35 apples

so, converting firstly the mixed fractions to improper fractions and then "adding".

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
