Step-by-step explanation:
The equation is given as :
Initial Amount,
(a) After One Day i.e. x=1
Amount Left,
(b)After 12 days, x=12
Amount Left,
To find this answer, divide 6 by 3/4 or 0.75. From this you get 8. It would take 8 days to paint six houses.
Answer:
4×5 = 20 m
20 :1 = 20 fundite a făcut, în total 20 de tăieturi
Solution:
<u>Note that:</u>
- Triangle = 180°
- 5x + 130 + 3x + 2 = 180
<u>Simplify the equation to find x.</u>
- 5x + 130 + 3x + 2 = 180
- => 8x + 130 + 2 = 180
- => 8x + 2 = 180 - 130
- => 8x = 50 - 2
- => 8x = 48
- => x = 48/8 = 6
The value of x is 6.
