Answer:
Apples = 24
Pears = 40
Step-by-step explanation:
Let u be the unit of fruit in the basket,
number of apples:
number of pears:
now to find u, we equate the two equations.

Now we can find the original number of apples and pears by substituting u.
so original number of apples =
and original number of pears =
Answer:
7
Step-by-step explanation:
To solve this you just have to replace the letters with the corresponding numbers. 5/5 = 1 and 1+6 = 7
So your answer is 7!
We need to start from the innermost parenthesis and work our way out.
The first parenthesis is . These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have
and 2z and -13z are like terms, so we can sum them:
Finally we arrive to the whole expression, which is
Because, again, 5z and 11z were like terms.
