1) A bar diagram with 2 shaded squares and 8 unshaded squares.
Answer:
(10q-p)/30=r
Step-by-step explanation:
p=10(q-3r)
distribute
p = 10*q - 10* 3r
p = 10q - 30r
subtract 10q from each side
p-10q = 10q-10q-30r
p-10q = -30r
divide by -30
(p-10q)/-30 = -30r/-30
-(p-10q)/30 =r
distribute
(-p+10q)/30 = r
i would rewrite to put the positive term 1st, put that is a personal choice ( my negative get lost in the parenthesis)
(10q-p)/30=r
