Answer:

Question 1)

5x

Question 2)

0.22a

Question 3)

8 + 6n

Question 4)

25

Question 5)

ab+c=14

Step-by-step explanation:

Ques 1)

The product of 5 and x.

Product of two numbers means that it is obtained by multiplying them.

Hence, the expression so obtained is: 5x

Ques 2)

22% of a

It means that:

22%×a

Also, we know that:

22% =0.22

This means that:

22% of a=0.22×a

i.e.

22% of a=0.22a

Ques 3)

8 more than the product of 6 and n.

The product of 6 and n is given by: 6n

and 8 more than there product will be given by:

8+6n

Ques 4)

Evaluate: 30 − m/6 for m = 30

i.e. we put m=30 in the expression and get the resulting value.

i.e. we have:

30-m/6=30-(30/6)

i.e.

30-m/6=30-5

i.e.

30-m/6=25

Ques 5)

Evaluate ab + c for a= 2, b = 5, c = 4.

i.e. we will put the value of a,b and c in the given expression and find the value.

i.e.

2×5+4= 10+4

i.e.

ab+c=14
