When n basketball uniforms are purchased, the cost, C, of each uniform is given by the equation.
1 answer:
Answer:
D. Subtraction property of equality; n = 15
Step-by-step explanation:
Given equation that shows the cost of n basketballs uniforms,
C = 40n + 260
According to the question,
Total cost = $ 860,
⇒ 40n + 260 = 860
Using subtraction property of equality, subtract 260 on both sides,
⇒ 40n = 860 - 260
⇒ 40n = 600
Using division property of equality, divide both sides by 40.
⇒ n = = 15.
Hence, 15 uniforms were purchased.
i.e. Option D is correct.

Answer:
a) = 4.5
b) = 3.3
Step-by-step explanation:
Before solving our problems given to us let us under stand the rule of cube roots
It says -----(A)
Also
---(B)
Now let us see each part one by one
a) we have
Now 64 = 4 x 4 x 4
0.027 = 0.3 x 0.3 x 0.3
0.008 = 0.2 x 0.2 x 0.2
substituting these values
Applying Rule A in above
4.5
b) we have
Applying the B rule in this
3.3
