Explain why 2a+3b=5ab
Ahat [919]

That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.

If you had 2a+3a, then it would simplify to 5a

Similarly, 2b+3b = 5b

Or you could have 2ab+3ab = 5ab

The key is that the variable portions must match up to be able to add them.

explain how to use missing pieces strategy to compare two fractions. include a diagram with your explanation
Artemon [7]

<span>The missing pieces strategy is another method to compare two fractions. To tell which number is larger, you ned to see which one is missing less. For example you have ¾ versus 4/5. Each of these fraction needs 1 to complete the whole. You need to subtract the numerator with one to compare them. For ¾ we have ¼ and for 4/5 we have 1/5. You know that if you complete 4/5 you will get 5 and for ¾ you will get 4. You know that 5 is greater than four. Therefore, 4/5 is larger than ¾.</span>

Mr. Nguyen bought a package of 4 chicken legs and a package of 6 chicken wings. Ms. Dawen bought a package of 3 chicken legs and
gulaghasi [49]

Answer:

weight of legs - 7 ounces

weight of wings - 4 ounces

Step-by-step explanation:

Let the weight of a chicken leg be represented by l

Let the weight of a chicken wing be represented by w

The total weight of Mr. Nguyen's package can be represented by this equation :

4l + 6w = 52

The total weight of Ms. Dawen's package can be represented by this equation :

3l + 6w = 45

To find the weight of the legs and wing, use simultaneous equation

4l + 6w = 52 eqn 1

3l + 6w = 45 eqn 2

Subtract equation 2 from 1

l = 7 ounces

Substitute for l in equation 1

4(7) + 6w = 52

28 + 6w = 52

Solve for w

w = 4 ounces
