1. 3(p+q)=p
3p+3q=p; 3p-p=3q; 2p=q so p=q/2
2. 4a=2b-7
2b=4a+7 so b=(4a+7)/2
when a=3 , b=(12+7)/2=19/2=9.5
3. d=rt; r=d/t
4.( 2x15)+(2xwidth)=90
2x width=90-30
width =60/2=30
A = LW
3,003.04 = 16L
3,003.04 / 16 = L
187.69 = L
so the painting can be 187.69 cm in length
Ok. <span>well the answer 1/2 the hour you paint 1/2 in 1/4 so add 1/2+1/2=1 so it is 2 so 1/4+1/4 </span>
