12 out of every 15 students owns a cell
phone. If there are 435
students surveyed, how
many do not own a cell
phone?

 348 students do not own a cell phone.

Step-by-step explanation:

12 out of 15 = 80%

80% of 435 = 348

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
