It dropped by 25 degrees (I'm assuming they are both either Celsius or Fahrenheit). 25 is a third of 75 (75/3 = 25). So, the answer will be letter a.

Quadrilateral ABCD is a rectangle. If AG = -7j + 7 and DG = 5j + 43, find BD
Kaylis [27]

<em>BD</em> = 56

Step-by-step explanation:

Step 1: In rectangle, the diagonals are congruent and bisect each other.

So, <em>AC</em> = <em>BD</em>

⇒<em>AG</em> + <em>GC</em> = <em>BG</em> + <em>GD</em>

⇒<em>AG</em> + <em>AG</em> = <em>GD</em> + <em>GD</em>

⇒ 2<em>AG</em> = 2<em>GD</em>

⇒<em>AG</em> = <em>GD</em>

⇒ –7<em>j </em>+ 7 = 5<em>j</em> + 43

⇒–7<em>j</em> – 5<em>j</em> = 43 – 7

⇒–12<em>j</em> = 36

⇒<em>j</em> = –3

Step 2: <em>BD</em> = 2<em>DG</em>

<em>BD</em> = 2(5<em>j</em> + 43)

     = 2(5 (–3) + 43)

     = 2(–15 + 43)

     = 2 × 28

     = 56

Hence, <em>BD</em> = 56.

How to solve equation an equation without y using elimination method
Sedbober [7]

Work only with the second equation at the beginning. Solve for x for it.

7x - 2x = 3                Combine the left hand side.

5x = 3                       Divide by 5

5x/5 = 3/5                Do the division

x = 3/5 = 0.6    

==============

Now work with the top equation.

3(0.6) + 5y = 13              Multiply on the left.

1.8 + 5y = 13                   Subtract 1.8 from both sides.

1.8 - 1.8 + 5y = 13 - 1.8    Do the subtraction

5y = 11.2                          Divide by 5

5y/5 = 11.2/5

y = 2.24                           Answer
