Answer:

Substituting for a Variable

If you know the value that the variable is equal to, you can substitute that value in for the variable in the expression! Let's look at an example. Since we know that x=5, we can directly substitute or replace the x in the expression x+3 with a 5 to solve for y!

there are students in a school. This number is 15% more than it was last year. Calculate the number of students last year
ANTONII [103]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let's help out by giving some values to the question.

Let's say there are 230 students in a school. This number is 15% more than it was last year. Calculate the number of students last year.

Let the number of students last year be x.

Since there's a 15% increase, this implies that (100% + 15%) = 115% of x equals to 230. This will be:

115% of x = 230

115% × x = 230

115/100 × x = 230

1.15x = 230

x = 230/1.15

x = 200

There were 200 students last year.

Just assign the missing values and use the above method and you'll get your answer.

Name
PtichkaEL [24]

Answer:

3 bars

Step-by-step explanation:

Total no. of gold bars = 24.

Fraction of bar captain allocated to himself = 1/3 of the bars

no. of bars he allocated to himself =  1/3 of 24 = 1/3 * 24 = 8

Fraction of bar captain allocated to his friend bill = 1/4 of the bars

no. of bars he allocated to his friend bill =  1/4 of 24 = 1/4 * 24 = 6

No . of bars captain allocated to rest of crew = 7

Total no of bars which are allocated altogether =

no. of bars he allocated to himself +no. of bars he allocated to his friend bill +No . of bars captain allocated to rest of crew

substituting the value of above summation variable as calculated above we have

Total no of bars which are allocated altogether = 8+6+7 = 21

No. of bars left = total no. of bars - Total no of bars which are allocated altogether = 24 - 21 = 3

Thus 3 gold bars are left.
