Activity 1:

Q/Circle the coefficient of each of these terms:

14d f) 3.5g

11k + 4 g) W

5.3e + 67 h) X

918273k + 87 I) k + 455

-5g j) 3X + 1

e) 14

f) 3.5 and 11

g) 1 and 5.3

h) 1 and 918273

i) 1 and - 5

j) 3

Step-by-step explanation:

A coefficient is the number or constant that multiplies a variable in an algebraic expression. It is placed before a variable.

We are to find the coefficient of each of the terms.

e) 14d

Considering the above definition, d is the variable. The coefficient to be circled is 14

f) 3.5g + 11k + 4

Considering the above definition, g and k are variables respectively.

The coefficient to be circled are 3.5 and 11 respectively

g) w + 5.3e + 67 = 1w + 5.3e + 67

Considering the above definition, w and e are variables respectively.

The coefficient to be circled are 1 and 5.3 respectively

h) x + 918273k + 87 = 1x + 918273k + 87

Considering the above definition, x and k are variables respectively.

The coefficient to be circled are 1 and 918273 respectively

I) k + 455 - 5g = 1k + 455 - 5g

Considering the above definition, k and g are variables respectively.

The coefficient to be circled are 1 and - 5 respectively

j) 3x + 1

Considering the above definition, x is the variable. The coefficient to be circled is 3

Note the answer to (f), (g) and (h) would be slightly different if the signs are opposite. That is if we have: x - 918273k + 87. Coefficient = - 918273

If 3.5g - 11k + 4, Coefficient = 3.5 and - 11

For w - 5.3e + 67, Coefficient = - 5.3 and 67

You can used the formula to find the omitted questions (a to d)
