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 cannot draw a graph so im going to explain
on the bottom u write per month and on the side and then increase the amount of money by 20$.
Answer:
2 hours = 7200 seconds
7200/15 = 480
25x480 = 12000 chirps in 2 hours
Step-by-step explanation:
Answer:
A. 0.625
B. 0
C. No
D. No
E. No
Step-by-step explanation:
We have these locations with the total of 56 as given in the question
A. Probability of landing anywhere but plain:
= 1 - probability of plain
= 1- 21/56
= 1 - 0.375
= 0.625
B. Probability of landing in a location which both a desert and a plain is the probability of a hit temperature and plain terrain. These two are independent of each other = 0
C. He cannot calculate probability of landing here because this information is not available
D. He cannot also, no information
E. Same thing here. No information
The answer is going to be
slope = 2
y-intercept= 5/4
