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
Expressions 4(x+5) and 5(x+4) are Equivalent
Expressions 5(2m+2) and 10m+10 are not equivalent
Step-by-step explanation:
Heres why,
4(x+5) and 5(x+4)
4 times x =4x, so multiply 4x by 5 which should give you 20.
and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.
5(2m+2) and 10m+10
times 5 to 2m to get 10m and times 10m by 2 to get 20.
10m+10 = 1 which they are not equivalent
The simplest form work be in a divide sign such as 2/3
I think the answer is 320miles,
3hs at 60mph = 180miles
2hs at 70mph = 140miles
so 180+140=320miles
