Answer:

<u>The two numbers are 23 and 56</u>

Step-by-step explanation:

Let's say the two numbers are A and B.

We are told:

1)  A+B=79

2) 3A+5B=283

Let's take the first expression and solve for A:

A+B=79

A=79-B

Now use this value of A in the second expression:

3A+5B=283

3(79-B)+5B=283

237-3B+5B=283

2B = 46

B = 23

Since B=23, we know from 1) that

A+B=79

A+23=79

A = 56

<u>CHECK:</u>

Does A+B=79?  

        56+23 = 79?  <u>YES</u>

Does 3A+5B=283?

3(56)+5(23)=283

168  + 115 = 283?  <u>YES</u>

Why does the fact family for 81 and 9 have only two number sentences
qwelly [4]
Because there are only two things you can do with these two " family" members. 81 divided by 9 is 9. 9 times 9 is 81. Strictly speaking, there should be three in the family: 9,9 and 81 9 is the square root of 81. 81 is the 9 squared.
