In a class of 40 students, the number of girls is 10 more than the number of boys. We have to find the number of girls and the number of boys in the class. Let’s represent the number of girls by g, and the number of boys by b. Write the pair of linear equations you will get in g and b :

b=15 g=25

Step-by-step explanation:

lets translate that story problem to mathematics equations

the problem told that no. of girls are 10 more than no of boys so this will =

g=b+10

then in class there are 40 students that means

g+b=40

now we have to equations with two variables then we should substitute

(b+10)+b=40

lets remove the brackets

2b+10=40 subtract 10 from both sides

2b=30 now divide both by 2

b=15 so g=25 after you write the equation once again with the new proof or number

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

answer: 2530

hope this
