X=y-4 Let's make this eqn 1 and

2x-5y=3 this eqn 2..


Two things are possible here...
Its either you substitute for x in equation 2... Or you substitute for y...

x=y-4 put this in the equation 2..

2x-5y=3.. Replace the x with (y-4)

2(y-4)-5y = 3...
Since this is In the option no point in substituting for y...

Hope this helped...?

Answer:

  • 40 sq. units

Step-by-step explanation:

<h3>Solution 1</h3>

The figure (kite) is symmetric and covers half of the area of rectangle with sides 8 units aby 10 units

<u>The area of the rectangle:</u>

  • A = 8*10 = 80 sq. units

<u>The area of the kite:</u>

  • A = 1/2*80 = 40 sq. units
<h3>Solution 2</h3>

Split the kite into two triangles and calculate their area and add up

<u>Triangle DCB has b = 8, h = 2 and has area:</u>

  • A = 1/2*8*2 = 8 sq. units

<u>Triangle DAB has b = 8, h = 8 and has area:</u>

  • A = 1/2*8*8 = 32 sq. units

<u>Total area:</u>

  • 8 + 32 = 40 sq. units

Elza [17]

3.5m + 2.5 = 79.5 is the equation that could be used to determine m, the number of miles in the taxi ride.

Given in question,

Pick-up fee = $2.50

Fee per mile = $3.50

Total fare = $79.50

Let the no. of miles = m

Fee for m miles = 3.50m

Equation, 3.50m + 2.50 = 79.50.

Hence, the equation is 3.50m + 2.50 = 79.50.

Answer:

  • r = √(3V/(πh))
  • r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

  V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}

For V=50, h=15, this is ...

  {r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}
