Answer:

$36

Step-by-step explanation:

Since 30% = 30/100 then we can transform it into a decimal:

30%=0.30

Now if we multiply 120•0.30, we will get how much we saved.

$36, we saved $36.

Bonus information:

If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

In a school of 2000 students, 1150 do not like puzzles. 2/5 of the students travel to school by bus. 595 of the people that do l
Vadim26 [7]

The number of students who do not like puzzles and ride the bus to school is 205

To find the answer it is necessary to do the following procedure:

To find out how many people the 2/5 traveling by bus are equivalent to, divide the total number (2000) of people by 5, and then multiply that value by 2.

  • 2000 ÷ 5 = 400
  • 400 × 2 = 800

From the above, it can be established that 800 people travel by bus to school. Now, to know how many people travel by bus and do not like puzzles, the following operation must be done.

Subtract the number of students who do like puzzles and ride the bus (595) from the total number of students who ride the bus (800)

  • 800 - 595 = 205

So the answer is 205 students ride the bus and they don't like puzzles.

Good morning ☕️

______

Answer:

x=4

___________________

Step-by-step explanation:

-Solving:

2x + 5 – 3 (2x - 7) = 2 (3x – 5) – 4

2x + 5 – 6x + 21 = 6x – 10 – 4

-4x + 26 = 6x - 14

10x= 26+14

10x=40

x=4

-Checking:

x=4

2(4) + 5 – 3 (2(4) - 7) = 8+5-3(8-7) = 13-3(1) =13-3=10

2 (3(4) – 5) – 4 = 2(12-5)-4 = 2(7)-4=14-4=10.
