two number have a sum equal to 50. their difference is 16. to figure out what the number are, you must first identify the varibles. what are the variables in this problem?
between them, kristen and brad have 68 cousins. brad has 10 more cousins than kristen. how many cousins does kristen have?
kristen has 28 cousins. Subtract 10 from 58. just make sure that the total adds to 68
i sorry...i meant to say kristen has 58 cousins... subtract 10 from 68 then make sure the total adds to 68. Disregard first response
Let x = one number and x + 16 the other.
x + x + 16 = 50
2x = 34
x = 17
Can you take it from there?
Let x = Kristen's cousins and x +10 = Brad's cousins.
x + x + 10 = 58
Solve similar to first problem.
To solve this problem, let's first identify the variables involved. Variables are unknown quantities that we need to find out.
Let's assume the two numbers are represented by variables. In this case, we can call the first number "x" and the second number "y".
So, the variables in this problem are:
- First number: x
- Second number: y
We can now proceed to solve the problem using algebraic equations.
