Answer:
x=1
Step-by-step explanation:
1). first combine -3+12. ( without the variable )
2). -3+12=9
3). therefore -3×1= -3

can you help me with my question
35 is the 'is' and 40 is the 'of'
is/of = %/100
35/40 = x/100
cross-multiply to get:
40x = 3500
x = 3500/40
x = 87.5
it is because 20 + 20 is 40 and then 40 - 20 = 20
