[section 2][formulas]
(1.) A = s2 when
s = 3 here is the problem
A = (3)2 replace s with 3
A = 9 square the 3
result: A = 9
(2.) B = 2t - 1 when
t = 2 here is the problem
B = 2(2) - 1 replace t with 2
B = 4 - 1 multiply
B = 3 subtract
result: B = 3
(3.) C = (5/9)(F - 32) when F =
68 here is the problem
C = (5/9(68 - 32) replace F with 68
C = (5/9)(36) subtract
C = 20 multiply
result: C = 20
(4.) S = 180(n - 2) when n = 5 here is the problem
S = 180(5 - 2) replace n with 5
S = 180(3) subtract
S = 540 multiply
result: S = 540
(5.) A = P[1 + 0.06t] when P = 1500 & t = 5
[here is the problem]
A = 1500[1 + 0.06(5)] replace P & t with 1500 & 5
A = 1500(1 + 0.3) multiply
A = 1500(1.3) add
A
= 1950 multiply
result: A = 1950
(6.) U = P/n when P = 4.59 & n = 2.4
[here is the problem]
U = 4.59/2.4 make substitutions
U = 1.9125 divide
result: U = 1.9125
(7.) V = LWH when L = 4; W = 2.5, H = 6
[here is the problem]
V = (4)(2.5)(6) make substitutions
V = 60 multiply
result: V = 60
(8.) A = (pi)r2 when r = 20 here is the problem
A = (pi)(20)2 replace r with 20
A = 400pi square the 20
result: A = 400pi
(9.) A = (pi)r2 when r = 9
here is the problem
A = (pi)(9)2 replace r with 9
A = 81pi square the 9
result: A = 81pi
(10.) C = 2(pi)r when r = 50 here is the problem
C = 2(pi)(50) replace r with 50
C = 100pi multiply
result: C = 100pi
