Answer:

n = -33

Step-by-step explanation:

Let n = number

Sum of a number and 9

(n+9)

is tripled

3(n+9)

the result is six less then twice the number

2n-6

3(n+9) = 2n-6

Distribute

3n+27 = 2n-6

Subtract 2n from each side

3n-2n +27 = -6

n +27 = -6

Subtract 27 from each side

n+27-27 = -6-27

n =-33

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number

professor190 [17]

Answer:

Number of calories in one slice of a 14 inch pizza is 189.825. 

Step-by-step explanation:

Given that 6 inch pizza has 650 calories. 

Therefore 1 inch pizza has $\frac{650}{6}$ calories. 

14 inch pizza will have

$\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories$

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

 $\frac {1516.66}{8} =189.825 calories$
