p = 100*a/b To calculate the value of a as a percentage of b, multiply a by 100 and then divide by b.

p / 4 = 16. Multiply both sides by 4: 4*p/4 = 4*16 ---> p = 64
16=24-p. subtract 16 both sides 0=8-p. add p both sides P=8
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
p/b=r/100 16/b=80/100 (16/80)100=b b=20 Check your work: 80% of 20 is 20x.8=16, work checked
The general idea in solving such equations it so get rid of everything, except the variable, on the left side. In this case, you have to add 16 to both sides. p - 16 = 64 p - 16 + 16 = 64 + 16 p + 0 = 80 p = 80 You can omit some of the steps when solving, I just included them for clarity: p - 16 = 64 p = 64 + 16 p = 80The general idea in solving such equations it so get rid of everything, except the variable, on the left side. In this case, you have to add 16 to both sides. p - 16 = 64 p - 16 + 16 = 64 + 16 p + 0 = 80 p = 80 You can omit some of the steps when solving, I just included them for clarity: p - 16 = 64 p = 64 + 16 p = 80The general idea in solving such equations it so get rid of everything, except the variable, on the left side.

P = 5 A = 6 B = 11 Or.... P = 1 A = 30 B = 55
p = 100*a/b To calculate the value of a as a percentage of b, multiply a by 100 and then divide by b.

p / 4 = 16. Multiply both sides by 4: 4*p/4 = 4*16 ---> p = 64
P = a + b + c + d, where a, b, c, d are sides. P = 2 × (a + b), where a and b are adjacent sides. P=2*(15.1+16) P=2*31.1 P=62.2 Answer: P= 62.2
16=24-p. subtract 16 both sides 0=8-p. add p both sides P=8
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
