shtirl [24]

Answer:

Step 3 contains error.

Step-by-step explanation:

The given equation is :

$\dfrac{1}{4}(\dfrac{1}{3}k+9)=6$

Step 1.

Cross multiplying,

$(\dfrac{1}{3}k+9)=24$

Step 2.

Subtract 9 from both sides

$\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15$

Step 3.

Cross multiplying

$k=15\times 3\\\\k=45$

So, there is an error in step 3. The correct answer should be 45.

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

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