Answer:
a, t = (p - 4)/5
b. t =√(a + 4)
c. t = d/(5-f)
Step-by-step explanation:
a. p = 5t + 4
To make t the subject of the equation, subtract 4 from both sides
p - 4 = 5t + 4 - 4
p - 4 = 5t
Divide both sides by 5
(p - 4)/5 = t
t = (p - 4)/5
b. a = t2 - 4
to make t the subject, add 4 to both sides
a + 4 = t2 - 4 + 4
a + 4 = t2
find the root of both sides
t =√(a + 4)
c. d = t(5 – f)
to make t the subject, divide both sides by 5 - f
d/(5-f) = t(5 – f)/(5 – f)
t = d/(5-f)
He had 250 shirts to begin with.
Let x be the number of shirts he began with. He has 10%, or 0.10 of the shirts now he had then. This equals 25:
0.1x = 25
Divide both sides by 0.1:
0.1x/0.1 = 25/0.1
x = 250
