The equation y = 0.1x + 1.61 can be used to predict the price per pound of ground beef, where x is the number of years since 199

alekssr [168]

2017 - 1996 = 21
So x = 21

y=0.1(21)+1.61
y=2.1+1.61
y=3.71

$3.71 is your answer

-2 1/4÷(-3 1/3)=? Solve into a simplified proper or improper fraction.

schepotkina [342]

Answer:

The answer is

Step-by-step explanation:

-2 1/4÷(-3 1/3)

First convert the mixed number to an improper fraction

That's

$- 2 \frac{1}{4} = - \frac{9}{4}$

And

$- 3 \frac{1}{3} = - \frac{9}{3}$

So we have

$- \frac{9}{4} \div - \frac{9}{3}$

Simplify

Change the division sign to multiplication sign and reverse the second number

That's

$- \frac{9}{4} \times - \frac{3}{9}$

Simplify

We have the final answer as

$\frac{3}{4}$

Hope this helps you
