Lol it is 23 for real this time
Ira Lisetskai [31]2 years ago

Answer:

lt the <u>no</u> s be x, x+1 and x+2 then x+(x+1)+(x+2)=72

x+x+x+1+2=72

3x + 3 = 72

3x = 72 - 3

3x = 69 <em>(</em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>"</em><em>3</em><em>"</em><em>)</em>

<em> </em><em> </em><em> </em><em>we</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>23</em>

<em> </em>

<em>so</em><em> </em><em>the</em><em> </em><em>numbers</em><em> </em><em>are</em><em> </em><em>23</em><em>,</em><em> </em><em>24</em><em> </em><em>and</em><em> </em><em>25</em>

When Liz woke up in the morning, it was 6°F. By the late afternoon, the temperature had dropped 9°F.
Annette [7]

Given:

Temperature in the morning = 6°F.

By the late afternoon, the temperature had dropped 9°F.

To find:

The temperature by the late afternoon.

Solution:

Temperature by the late afternoon = Morning temperature - Dropped temperature

Using the given values and the above formula, we get

Temperature by the late afternoon = 6°F - 9°F

Temperature by the late afternoon = -3°F

Therefore, the temperature by the late afternoon is -3°F.

Find the approximate perimeter of rectangle ABCD plotted below. B(4,5) AC -6,0) C(8,-3) D(-2,-8) Choose 1 answer: Do 5 problems
Likurg_2 [28]

Answer:

Perimeter of rectangle ABCD = 47.62

Step-by-step explanation:

The perimeter of a rectangle is P = 2(length + width)

You need to find length and width

If you graph, you can pick your length length and your width

Pick two points after you graph, for (x_{1},y_{1})  and (x_{2},y_{2})

Use the distance formula to find the length =\sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} ^{2})}

point B (4,5) will be point 1 and point C (8,-3) will be point 2

Substitute

length =\sqrt{(8 - 4 )^{2} + (-3- 5 )^{2}}\\

length = \sqrt{80}

length = 8.94

Use the distance formula to find the width =\sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} ^{2})}

point C (8,-3) will be point 1 and point D (-2,8) will be point 2

Substitute

width =\sqrt{(-2 - 8 )^{2} + (8- (-3) )^{2}}\\

width =\sqrt{(-10 )^{2} + (11 )^{2}}\\

width =\sqrt{100 + 121}\\

width = \sqrt{221}

width = 14.87

Now use formula P = 2(length + width)

P = 2(8.94 + 14.87)

Perimeter of rectangle ABCD = 47.62
