Answer:
5. 100/b+24 6. 5m+13
Step-by-step explanation:
5. The quotient means Divide. The sum means Add. So / is z symbol for division. 100 divided by b plus 24.
6. More means to Add and the product means to multiply. So instead of putting m times 5, you would put 5m. First you would put 5m+ 13 b/c of the "than".
With 
, we have
Then the difference quotient is
since <em>h</em> ≠ 0.
The grocer wants to make a 10 pound mixture
p - pounds of peanuts
c - pounds of cashews
therefore the total pounds should be equal to 10 pounds
p + c = 10 -----> 1)
the cost for ;
peanuts - 4.00 per pound * p pounds = 4p
cashews - 6.50 per pound * c pounds = 6.5c
the price of 10 pounds mixture = 4.75 per pound * 10 pounds = 47.5
4p+6.5c = 47.5 ---> 2)
to solve for p and c lets use simultaneous equations
p + c = 10 -----> 1)
4p+6.5c = 47.5 ---> 2)
multiply 1st equation by 4
4p + 4c = 40 ---> 3)
subtract 3rd equation from the 2nd
2.5c = 7.5
c = 3
substituting c= 3 in 1st equation
p+c = 10
p+3 = 10
p = 7
therefore 3 pounds of cashews and 7 pounds of peanuts are needed to make the mixture
