Answer:

31

Step-by-step explanation:

Here the trick is to perform the indicated operations in the correct order.  Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.

Doing the work inside parentheses first:

(3 × 22) ÷ 6 + [28 – (4)2]  =>  (66) ÷ 6 + [28 - 8], or

(66) ÷ 6 + [28 - 8]  =>  11 + [20], or 31

Answer: The second option and the third option are true.

Step-by-step explanation:

The formula of the line in slope-intercept form is:

y=mx+b

Where <em>m </em>is the slope and <em>b </em>is the y-intercept.

By definition, the y-intercept in a direct variation is 0.

Therefore, substituting m=-3 and b=0 into the equation, you obtain:

y=-3x+0

Then, the equation is:

y=-3x

As this is a line, it is a linear function.

Therefore, the second option and the third option are true.

lutik1710 [3]

Answer:

1.09 $

Step-by-step explanation:

From  1990 to 2000  ( 10 years ) the consumer price index  increased from

130.7  to  172.2 then

172,2  -  130.7   =  41.5 %  was the net increase, if peaches suffered similar increase then we will look for 41.5 %  of peaches price ( 1990)

0,77     ⇒   100

x ??      ⇒    41.5

x  =  0,77* 41,5 / 100

x  =  0,3196

Then price of a pound peaches in 2000  will be

0,77  +  0,32   =  1.09 $
