Solve & Evaluate

100

Solve for t

d = rt  

t=d/r

200

Solve for c

a = 46c

c=a/46

300

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

400

The formula

C=2pir

relates the circumference C of a circle to its radius r. Solve for r.

r=c/(2pi)

500

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 

Solving I

100

Solve for m

m - n = 5 

m = 5 + n

200

Solve for x

x/5-g=a

x = 5(a + g)

300

Solve for b 

2a + 2b = c 

b=(c-2a)/2

400

Solve for x

3.3x + r = 23.1 

x=(23.1-r)/3.3

500

Solve for g

s=1/2gr^2

g=(2s)/r^2

Solving II

100

Solve for m

m/k=x

 

m = xk

200

Solve for x 

y = mx + b 

x=(y-b)/m

300

Solve for r

ax + r = 7 

r = 7 - ax

400

Solve for a

2a - 4b = c 

a=c/2+2b

a=(c+4b)/2

500

Solve for s

v^2=u^2+2as

s=(v^2-u^2)/(2a)

Solving III

100

Solve for t

5 - b = 2t 

t=(5-b)/2

200

Solve for T

PV = nRT 

T=(PV)/(nR)

300

Solve for x

4y + 3x = 5 

x=(5-4y)/3

400

Solve for y

0.6x + 1.4y = 0.4 

y=(0.4-0.6x)/1.4

500

Solve for t

S=(hwft)/(35,000)

t=(35,000S)/(hwf)

Solving IV

100

Solve for m

D=m/V

m = VD

or m = V x D

200

Solve for T

M = T - R 

T = M + R

300

Solve for x

9 + 3x = 2y 

x=(2y-9)/3

400

Solve y = mx + b for m.

m=(y-b)/x

500

Solve for d:

t=d/500+1/2

d=500(t-1/2)

or

d=500t-250
