9. r = d/t
For d, multiply both sides by t.
10. y = 3x - 10
How did you get 7x?
3. (P - 21)/2 = w
can someone help me figure these literal equation out? I did them before but my teacher said they were incorrect.
Questions~~
Solve the following formula for the variable indicated
9. r = d/t, where r = rate, d = distance, and t = time for d
( I didn’t know how to answer this one in the first place)
10. 3x - y = 10 for y
My answer~
3x-10
3x-10=7x
What my teacher said~~ Please go back and look at the examples at the end of the lesson.
Examples from the lesson~
Ex. 2 Solve d = m for m
V
d = m Isolate the m using the inverse operation of
V division which is multiplication of V.
V(d) = m (V)
V
Ex. 3 Solve P = 2l + 2w for w
P = 2l +
-2l = -2l
P – 2l = 2w
2 2
P – 2l = w
