Answer:

The two numbers are 23 and 56

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

CHECK:

Does A+B=79?

56+23 = 79? YES

Does 3A+5B=283?

3(56)+5(23)=283

168 + 115 = 283? YES

31.693 Rounded to the nearest Hundredth

ioda

Hi there!

»»————-　★　————-««

I believe your answer is:

31.69

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

'9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
Since 3 is less than or equal to 4, we would round down.

⸻⸻⸻⸻

31.693 ≈ 31.69
