Jerome wrote the following scenario to match the algebraic expression s4
− 16:
“16 fewer than four times the number of songs on my mp3 player”
Does his scenario match the expression? Explain.

Answers

No, Jerome’s scenario does not match the expression. The term s4 means the number of songs is divided by four, but the scenario uses the word ‘times,’ which means multiplication. The scenario should say ‘16 fewer than one-fourth the number of songs.’

Answer:

The scenario does not match.

Jerome should have used division instead multiplication.

16 fewer than the number of songs divided by 4.

{ \left( \frac { 1 }{ 2 } \right) }^( 4 )\n \n =\frac { 1 }{ 2 } \cdot \frac { 1 }{ 2 } \cdot \frac { 1 }{ 2 } \cdot \frac { 1 }{ 2 }

\n \n =\frac { 1 }{ 2\cdot 2\cdot 2\cdot 2 } \n \n =\frac { 1 }{ 16 }

It is because (1/2)^4 is equal to 1/2*1/2*1/2*1/2 which equals 1/16

Jackson has a rope 1 foot 8 inches long. He cuts it into 4 equal pieces. How many inches long is each piece?

Answers

1 foot  8 inches.

1 foot = 12 inches.

1 foot  8 inches = 1 foot + 8 inches = 12 inches + 8 inches = 20 inches.

He cuts into 4 equal pieces.

=  20 / 4

= 5 inches.

Each piece would be 5 inches long.
Each individual piece of rope is 5' long! We all know that a foot is 12' so that plus the extra 8' equals 20'... 20' divided by four which is the amount it was cut into, is 5' !!!

N/2+4=-4. I need help I cannot figure this out and I left.my math binder at my school. :/ plz halp :3

Answers

(n)/(2) +4=-4

Multiply both sides by 2 :

(n)/(2) *2+4*2=(-4)*2

n+8 =-8

Subtract 8 from both sides:

n+8-8=-8-8

n=-16

hope this helps!
first subtract four from both sides and get n/2=-8. Then multiply both sides by 2 and get n=-16
