60 as the product of
prime factors is
2 + 3 +2 + 5
3a + 3b - 2a + 2b
=a+b
2 + 4 ÷ 2= 4
-2-6=8
15.46897654 to 3
significant figures
3a + 3 = 12
Is 15.469
a=5
TWO IS THE
MAGIC NUMBER!
Only two of these cards
are correct … but which
two??
3(y + 5)
3a = 15
= 3y + 5
Area = 1 x 1

3y - y = 3
1/3 + 2/5 = 3/8
= 1 cm2
- 3 x - 8 = -24
1cm
2 cm
3(y + 2) - 2(y - 4)
= 3y + 6 - 2y - 8
