Answer:

Shirt= $5.50

Pant=$10

Step-by-step explanation:

Let's shirt be 'x' and pant be 'y' 

 =}. 3x + y = $26.50

 4x + 2y = $42

=}. 3x + y = $26.50

 2x + y = $21. ( then first term minus 

 second term )

=}. x = $ 5.50

Now, y = $26.50 - 3x

 = $26.50 - 16.50

 = $10

the NACI cafeteria wants to sell two 25 cm diameter medium size pizzas for the same price as one large pizza. what should the di

Alex777 [14]

Answer:

35.34 centimeters

Step-by-step explanation:

The amount of pizza is same as the area. The pizza is in a shape of a circle. The area of a circle is:

$A=\pi r^2$

Where

r is the radius (half of diameter)

Area of one medium size pizza is (diameter 25 means radius is 25/2 = 12.5):

$A=\pi r^2\\A=\pi (12.5)^2\\A=490.87$

So, area of two of these medium size pizzas is:

490.87 * 2 = 981.74

This should be the area of the large pizza. We can find the radius of that by substituting into formula. Shown below:

$A=\pi r^2\\981.75=\pi r^2\\r=\sqrt{\frac{981.74}{\pi}} \\r=17.67$

Hence, the diameter would be around:

17.67 * 2 = 35.34 centimeters

Please help. I am not good with this

aniked [119]

Answer:

X= 7

Z= 117

Step-by-step explanation:

Z would be 117 because on the bottom half of the equation it has to be equal to 180. It gave you 63 already and so I just took the 180 and subtracted the 63 to get 117.
