Annika sells 6 inch pies for $5.00 and 8 inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8 inc
Alina [70]
The question is
Find the values of x and  y

Let
x---------> the number of 6-inch pies Annika sold 
y--------> the number of 8-inch pies Annika sold 

we know that
x=2y------> equation 1
5x+9y=133---> equation 2
substitute the equation 1 in equation 2

5*[2y]+9y=133
10y+9y=133
19y=133
y=7
x=2y-----> x=2*7-----> x=14

the answer is
the number of an 6-inch pies is 14
 the number of an 8-inch pie is 7

Which model represents the factors of 4x2 – 9?
GREYUIT [131]
The factors of 4 x² - 9 :
4 x² - 9 = ( 2 x - 3 ) · ( 2 x + 3 )
We have to use the formula for the difference of squares:
a² - b² = ( a - b ) · ( a + b )

Look at the picture.

\cos 36^\circ = \frac{x}{12} \\
0.809 \approx \frac{x}{12} \\
0.809 \times 12 \approx x \\
x \approx 9.708

The base of the ladder is approximately 9.708 feet from the tree trunk base.

xeze [42]

Answer:

D. x-\frac{5}{2}y =  \frac{25}{2}

Step-by-step explanation:

Given

y = \frac{2}{5}x - 5

Required

Determine its equivalent

<em>From the list of given options, the correct answer is</em>

x - \frac{5}{2}y = \frac{25}{2}

This is shown as follows;

y = \frac{2}{5}x - 5

Multiply both sides by \frac{5}{2}

\frac{5}{2} * y = \frac{5}{2} * (\frac{2}{5}x - 5)

Open Bracket

\frac{5}{2} * y = \frac{5}{2} * \frac{2}{5}x - \frac{5}{2} *5

\frac{5}{2}y = x - \frac{25}{2}

Subtract x from both sides

\frac{5}{2}y - x = x -x - \frac{25}{2}

\frac{5}{2}y - x = - \frac{25}{2}

Multiply both sides by -1

-1 * \frac{5}{2}y - x * -1 = - \frac{25}{2} * -1

-\frac{5}{2}y + x =  \frac{25}{2}

Reorder

x-\frac{5}{2}y =  \frac{25}{2}

<em>Hence, the correct option is D</em>

x-\frac{5}{2}y =  \frac{25}{2}
