Answer:

3 pizza slices.

Step-by-step explanation:

We have been given that Desmond ordered his favorite pizza with 12 slices. Sadly, he could finish only 75% of the whole pizza.

As Desmond ate 75% of 12 slices, so left number of slices will be equal to 25% of 12 slices.

\text{Number of pizza slices left}=\frac{25}{100}\times 12

\text{Number of pizza slices left}=\frac{1}{4}\times 12

\text{Number of pizza slices left}=3

Therefore, 3 pizza slices were left.

let 

x--------------------- > numbers of television sold

y--------------------- > numbers of computer sold 

then 

72x+90y >= $360 ----------- >72x/72+90y/72 >= $360 /72---- >x+1.25y >= $5

y >= (5-x)/1.25--------------see the graph in attached figure 

 

case A---------- > (5,2) (3,3)  (1,4)

72x+90y --------- > 72*5+90*2=540 >= 360----- > is solution

72x+90y --------- > 72*3+90*3=486 >= 360----- > is solution

72x+90y --------- > 72*1+90*4=432 >= 360----- > is solution

What’s the value of x in 3x - 10 = 11
Lina20 [59]

First add 10 to both sides:

3x-10=11+10

3x=21

Divide three by both sides to get x by itself:

3x/3=21/3

x=7
