3q − p + 10 – 9t

What is the coefficient of t?

• 3

• 9

• -9

• 10

Jamila has k + 3 counters.

If she doubled her number of counters she would have:

• 2k-6

• 2k+6

• k+6

• 12k+6

Each cup contains p counters.

The total number of counters is:

(a)  

When r = 5 and p = 2, evaluate 10r − p.

• 47

• 52

• 50

• 48

a = 5, b = 4 and c = 0 therefore:

abc =

(a)  

If r = 5 and p = 3 , evaluate r − 4p.

(a)  

Work out by collecting like terms: 7a + 3a =

(a)  

Which expressions below have two terms?

 

 

• x + y + 5

•  2 − 3m

•  p × y

• 5kp − mn

Expand the brackets: 2(4 − p) =

(a)  

Expand this expression and then collect like terms:

7(m + 3) − 5=

• 7m+21

• 7m+16

• 7m-16

• 7m+15
