First attempt to break the top portion up so the negative signs don’t confuse you.

(2 x -2) x (-2 x -4)/ 2 x 2

= (-4) x (8)/ 4

= -32/4

= -8

*Remember that multiplying two negative numbers give you a positive number

a bagel cost $0.80.On Wednesday ,a dozen bagels cost $6.00. what is the unit price of a bagel on wednsday, if you buy 3 bagels?
maria [59]

If a bagel costs $0.80 any day, then the unit price
is $0.80 per bagel.

If the unit price of a bagel is $0.80 , then every bagel
you buy costs $0.80 .

Only one thing changes:  The price of a dozen on Wednesday.

If you buy 1 dozen ... or any number of dozens ... on Wednesday,
then the unit price of the contents of that bag is

                        ($6.00) / (1 dozen)  =  $6.00 per dozen

If you want to convert that to a
different unit of measure, then
you do it like this:

                 (6.00  $/dozen) x (1 dozen/12 bagels)

             =  (6.00 x 1 / 12)  ($/bagel)

             =        0.5  $/bagel

                 or   $0.50 / bagel .

It is an odd number. it is greater than 142. it is less than 156. rounded to the nearest ten, the rounded value is less than the
GaryK [48]
The odd numbers between 142 and 156 are these:

143, 145, 147, 149, 151, 153, and 155.

Of these, 143 to the nearest ten is 140.

Likewise, 151 to the nearest ten is 150.

And, 153 to the nearest ten is 150.

Of the seven original numbers, 143, 151, and 153 round to a nearest ten that
 is less than the possible mystery number.

To the nearest hundred, 143 goes to 100; 151 goes to 200, and 153 goes to 200.

Of those three, only two round to a nearest hundred that is bigger than the mystery number.

Answer:  151 and 153 are the mystery numbers.

Choose the equation that has solutions (5,7) and (8,13).
Alekssandra [29.7K]
<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

(x_{1},y_{1}) is called solution of a equation if (x_{1},y_{1}) satisfies the equation.

Consider the equation y=2x-3,

For point (5,7),

LHS=y=7

RHS=2x-3=2(5)-3=10-3=7

So,RHS=LHS

The point (5,7) satisfies the equation.

For point (8,13),

LHS=y=13

RHS=2x-3=2(8)-3=16-3=13

So,RHS=LHS

The point (8,13) satisfies the equation.

So,both the points satisfy the equation y=2x-3
