Solve & Evaluate
Solve for t
d = rt
t=d/r
Solve for m
m - n = 5
m = 5 + n
Solve for m
m/k=x
m = xk
Solve for t
5 - b = 2t
t=(5-b)/2
Solve for m
D=m/V
m = VD
or m = V x D
Solve for c
a = 46c
c=a/46
Solve for x
x/5-g=a
x = 5(a + g)
Solve for x
y = mx + b
x=(y-b)/m
Solve for T
PV = nRT
T=(PV)/(nR)
Solve for T
M = T - R
T = M + R
The formula A=P+I shows that the total amount of money A received from an investment equals the principal P (the original amount of money invested) plus the interest I. Solve this formula for I.
I = A - P
Solve for b
2a + 2b = c
b=(c-2a)/2
Solve for r
ax + r = 7
r = 7 - ax
Solve for x
4y + 3x = 5
x=(5-4y)/3
Solve for x
9 + 3x = 2y
x=(2y-9)/3
The formula
C=2pir
relates the circumference C of a circle to its radius r. Solve for r.
r=c/(2pi)
Solve for x
3.3x + r = 23.1
x=(23.1-r)/3.3
Solve for a
2a - 4b = c
a=c/2+2b
a=(c+4b)/2
Solve for y
0.6x + 1.4y = 0.4
y=(0.4-0.6x)/1.4
Solve y = mx + b for m.
m=(y-b)/x
The formula for a person's typing speed is s = w-10em where s is speed in words per minute, w is number of words typed, e is the number of errors, and m is the number of minutes typing. Solve for w
w = s + 10em
Solve for g
s=1/2gr^2
g=(2s)/r^2
Solve for s
v^2=u^2+2as
s=(v^2-u^2)/(2a)
Solve for t
S=(hwft)/(35,000)
t=(35,000S)/(hwf)
Solve for d:
t=d/500+1/2
d=500(t-1/2)
or
d=500t-250
