Solve & Evaluate
Solve d=rt for t
t=d/r
Solve m - n = 5 for m
m = 5 + n
Solve for m:
m/k=x
m = xk
Solve 5 - b = 2t for t
t=(5-b)/2
Solve for m:
D=m/V
m=VD
Solve a=46c for c
c=a/46
Solve for x:
x/5-g=a
x = 5(a + g)
Solve y = mx + b for x
x=(y-b)/m
Solve PV = nRT for T
T=(PV)/(nR)
Solve M = T - R for T
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 2a + 2b = c for b
b=(c-2a)/2
Solve ax + r = 7 for r
r = 7 - ax
Solve 4y + 3x = 5 for x
x=(5-4y)/3
Solve 9 + 3x = 2y for x
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 3.3x + r = 23.1 for x
x=(23.1-r)/3.3
Solve 2a - 4b = c for a
a=c/2+2b
a=(c+4b)/2
Solve 0.6x + 1.4y = 0.4 for y
y=(0.4-0.6x)/1.4
Solve for d:
t=d/500+1/2
d=500(t-1/2)
or
d=500t-250
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 y = mx + b for m.
m=(y-b)/x
