Answer:
A. -0.45
Step-by-step explanation:
Step-by-step explanation:
4.5 × 10
= 45
this is the answer
Step-by-step explanation:
If the cost of 5m cloth is Rs.375
Then cost of 80m cloth is (80m× Rs 375)÷ 5m
then the cost of is 6000 Rs. you can use the criss cross method
5m = 375 Rs
80m = ?
80 × 375 = (30,000) ÷5
?= 6000
Answer: D. 2,800
Explanation: (3•1,000)= 3,000
(2•100)= 200
3,000-200= 2,800
506 x - 92 y + 90 = 498 - 4 x + 6 y
Geometric figure:
line
y = (255 x)/49 - 204/49
510 x - 98 y - 408 = 0
506 x - 92 y + 90 = 6 (y + 83) - 4 x
Real solution:
y = (255 x)/49 - 204/49
Solution:
y = (255 x)/49 - 204/49
Integer solution:
x = 49 n + 40, y = 255 n + 204, n element Z
Solution for the variable y:
y = 51/49 (5 x - 4)
