Four-fifths of a number minus two is greater than three-tenths of twice that number

1 answer:

3 0

Let x be a number and four-fifths of a number means 4/5x and then minus 2 =
4/5x - 2
three tenths of twice that number = 3/10 x 2x
the expression will be:
4/5x-2>3/10 x 2x
4/5x-2>3/5x
4/5x - 3/5x > 2
1/5x > 2
x > 10

Gilda walks to the train station. If she walks at the rate of 3 mph, she misses her train by 7 minutes. However, if she walks at

lorasvet [3.4K]

We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph

d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
