Answer:
The equation is 21x+4y<3150
Step-by-step explanation:
This question can be understood by the concept of inequalities.
Let x be the number of stocks of software company and y be the number of stocks of robotics company purchased.
Money invested in 1 stock of software company = $42
Money invested in 1 stock of robotics company = $8
Total expenditure on software company stock = 42*x
Total expenditure on robotics company stock = 8*y
So the total expenditure should be less than 6300
Hence the equation is
42x+8y<6300
21x+4y<3150

Answer:
-65
Step-by-step explanation:
1 - 4 / 7 = 3 / 7 ( It means that it is 3 / 7 of the aquarium left to fill with water )
5 / 6 L ------ 4 / 7
x L --------- 3 / 7
5 / 6 : x = 4/7 : 3/7
5 / 6 : x = 4 : 3
4 x = 3 * 5/6
4 x = 15/6
x = 15/6 : 4
x = 5/2 : 4 = 5/8 L
Answer:
Jacob needs 5/8 L more to fill the aquarium,
or 5/6 + 5/8 = 35/24 L ( in total ).
