Answer:
x = 3.5
y = - 4
Step-by-step explanation:
2(4x + 7y = -14)
8x + 14y = -28
8x + 5y = 8
- (8x + 14y = -28)
--------------------------
- 9y = 36
y = 36/-9
y = - 4
4x + 7y = - 14
4x + 7(- 4) = - 14
4x -28 = - 14
4x = 14
x = 14/4
x = 3.5
Answer:
The total number of automatic transmission car dealership sell = 728
Step-by-step explanation:
Given as :
Let the total number of standard transmission car = S
And the total number of automatic transmission car = 200 + S
The percentage of blue standard car = 15%
The percentage of blue automatic car = 10%
Total number of blue car sold = 152
∴ 15% of S + 10% of ( 200 + S ) = 152
Or, 15 S + 10 × ( 200 + S ) = 152 × 100
Or, 25 S = 15200 - 2000
Or, 2 5 S = 13200
∴ S = 
So, S = 528
I.e The total number of standard transmission car = S = 528
And the total number of automatic transmission car = 200 + 528 = 728
Hence The total number of automatic transmission car dealership sell = 728 Answer
Volume = Pi × radius squared × height
Radius = Diameter ÷ 2
= 8 ÷ 2
= 4 cm
Volume = Pi × 4 squared × 12
= Pi × 16 × 12
= 603.1857895...
= 603.19 cm cubed
Note : Pi is approximately equal to 3.14
