Answer:
-2
Step-by-step explanation:
5x – 15 > 10 + 20x
Subtract 5x from each side
5x – 15-5x > 10 + 20x-5x
-15 > 10+15x
Subtract 10 from each side
-15-10 >15x
-25 > 15x
Divide each side by 15
-25/15 > x
-5/3 > x
X must be less than -1 2/3
The only value that is less than -1 2/3 is -2
Nobody can solve this without any further information?
Answer:
Rs. 4,200,000
Step-by-step explanation:
Given :
Volume of brick = 500cm³
Dimension of wall : 200m×0.5m×1.5m
Converting to cm
Volume of compound wall:
(200 * 100) * (0.5 * 100) * (1.5 * 100)
20000cm * 50cm * 150cm=
= 150000000cm³
Volume of compound wall / volume of brick
1500000000 cm³ / 500 cm³
= 300000
Price per brick = Rs. 14
Total price = 14 * 300000 = Rs. 4,200,000
Answer:
60cm²
Step-by-step explanation:
Surface area of a triangular prism = 2B+ph
B is the base area = 6cm²
perimeter p = 12cm
altitude h = 4cm
Substitute
Surface area = 2(6) + 12(4)
Surface area = 12 + 48
Surface area = 60cm²
Answer:
y = -3x + 5
Step-by-step explanation:
You want it in y = mx + b form
-5 = -y - 3x
Add y to both sides
-5 + y = -y + y - 3x
-5 + y = -3x
Add 5 to both sides
- 5 + 5 + y = -3x + 5
y = -3x + 5
