This is wrong btw haha
Answer:
10 meters
Step-by-step explanation:
To calculate area of the triangle we multiply height with base and that divided by two
90 = (18 × w) ÷ 2
180 = 18w
w = 10 meters
Answer:
Cost of one chair = Rs . 150
Cost of one table = Rs. 500
Step-by-step explanation:
Let number of chairs denote x and no of tables denote y
4x + 3y = 2100 --------------------(i)
5x +2y = 1750 ------------------(ii)
Multiply equation (i) by 2 and (ii) by (-3) and now y will be eliminated.
(i)*2 8x + 6y = 4200
(ii)*(-3) -<u>15x - 6y = - 5250</u> {Now, add}
- 7x = - 1050
x = -1050/-7
x = Rs. 150
Plug in the value of x inn equation (i)
4*150 + 3y = 2100
600 + 3y = 2100
3y = 2100 - 600
3y = 1500
y= 1500/3
y =Rs 500
I is the answer to this equation I think
