Since my answer was deleted here it is:

The variable x represents the cost per pound of meat.

The variable y represents the cost per pound of cheese.

The deli charges $4.50 for a pound of meat.

Answer:

The cost of 1 pound meat is $ 4.5 And cost of 1 pound of cheese is $ 2.5.

Step-by-step explanation:

Let the cost of 1 pound of meat be x

Let the cost of 1 pound of cheese be y

Cost of 4 pounds of meat = 4x

Cost of 5 pounds of cheese = 5y

Since we are given that one customer purchases 4 pounds of meat and 5 pounds of cheese for a total of $30.50.  

So, equation becomes : 4x+5y = 30.50

Cost of 11 pounds of meat = 11x

Cost of 14 pounds of cheese = 14y

Since we are given that a sandwich shop owner comes in and purchases 11 pounds of meat and 14 pounds of cheese for $84.50.

So, equation becomes : 11x+14y = 84.50

Thus the system of equations are :

4x+5y = 30.50 -1   (Red line)

11x+14y = 84.50 -2   (Black line)

Solving these equations graphically we get the solution

x = $4.5

y = $2.5

Hence The cost of 1 pound meat is $ 4.5 And cost of 1 pound of cheese is $ 2.5.

A right square pyramid is pictured below. if l is 15 cm and x is 18 cm, what is the surface area of the pyramid?
Nady [450]

Answer:

The surface area of square pyramid is 953.64  cm² .

Step-by-step explanation:

Given as for a square pyramid :

The height of pyramid = l  = 15 cm

The base of square pyramid = x = 18 cm

Now,

The surface area of square Pyramid = b^{2} + 2b\times \sqrt{\frac{b^{2}}{4}+h^{2}}

or , The surface area of square Pyramid = x^{2} + 2x\times \sqrt{\frac{x^{2}}{4}+l^{2}}

Or, The surface area of square Pyramid = 18^{2} + 36\times \sqrt{\frac{18^{2}}{4}+15^{2}}

Or,  The surface area of square Pyramid = 324 + 36 × \sqrt{81 + 225}

or,  The surface area of square Pyramid = 324 + 36 × 17.49

Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²

Hence The surface area of square pyramid is 953.64  cm² .  Answer

A recipe calls for 2/3 cup of milk. If you make 3 1/2 times the recipe, how much milk do you need?
jeka57 [31]

To solve this problem, we need to multiply 2/3 by 3 1/2. We do this because we are making the recipe 3 1/2 times, which means we need the amount of milk for one recipe multiplied by the amount of times you are completing the recipe. To multiply these two numbers, we first need to convert 3 1/2 to an improper fraction. To do this, we multiply the denominator by the whole number and add the numerator, while keeping the same denominator. This is modeled below:

3 1/2 = (2*3 + 1)/2 = (6+1)/2 = 7/2

Now that we have this information, we can multiply our fractions together by simply multiplying the numerators and denominators together (straight across).

2/3 * 7/2 = (2*7)/(3*2) = 14/6

To simplify this fraction, we need to divide both the numerator and the denominator by the GCF, or greatest common factor, of the two numbers. The greatest common factor is 2.

(14/2) / (6/2) = 7/3

To convert this fraction into a mixed number, we must divide, and make the remainder into a fraction.

7/3 = 2 r 1 = 2 1/3

Therefore, your answer is 2 1/3 cups of milk.

Hope this helps!

MArishka [77]

Answer:

x= \frac{3-3\sqrt{7}i }{4} and x= \frac{3+3\sqrt{7}i }{4}

Step-by-step explanation:

We have to solve the given equation - 2x² + 3x - 9 = 0

To solve the equation given above we have to factorize the left-hand side of the equation.

But it can not be factorized. So, use the Sridhar Achaya formula.

Therefore, x= \frac{-3 + \sqrt{3^{2}-4 \times (-2) \times (-9) } }{2\times (-2)} and x= \frac{-3 -\sqrt{3^{2}-4 \times (-2) \times (-9) } }{2\times (-2)}

So,  x= \frac{3-3\sqrt{7}i }{4} and x= \frac{3+3\sqrt{7}i }{4} {Where i=\sqrt{-1}}

Therefore, the solutions are imaginary numbers. (Answer)

Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are x = \frac{-b + \sqrt{b^{2}-4ac } }{2a} and x = \frac{-b - \sqrt{b^{2}-4ac } }{2a}.
