Combine like terms . what is 43z + 15z + 7z + 5z + 46z + 14z? ​
Vladimir [108]

Basically just add them all together like normal addition except there is a z attached to each number:

43z + 15z + 7z + 5z + 46z + 14z

58z+ 7z + 5z + 46z + 14z

65z + 5z + 46z + 14z

70z + 46z + 14z

116z + 14z

130z

Hope this helped!

A pizza shop sells pizza by the slice. They must make two different sizes of pizza - a 12-inch pizza which they cut into 60-degr
Vadim26 [7]

Answer:

14 inch pizza.

Step-by-step explanation:

A pizza is the shape of a circle which is 360 degrees.

For the 12 in pizza, it is being divided into 60 degree slices.

360/60= 6 slices.

The area of the pizza is calculates with \pi *r^2 so we must find the radius of the pizza, r. 12 inch is the diameter which is 2r so half of the diameter= r.

12/2=6=r

So the area of the 12 inch pizza is = pi*6*6= 36\pi

36\pi/6 for 6 slices means each slice is 6 pi in area.

For the 14 inch pizza, it is being divided into 45 degree slices.

360/45= 8

The radius = d/2= 14/2= 7

The area = \pi*7*7 = 49pi

For each slice 49\pi/8= 6.125\pi

Since 6.125\pi > 6\pi that  means that the 14 inch pizza slice is a better deal because you get more food for the same amount of money.
