Answer:
61 m^3
Step-by-step explanation:
The difference in volume is (5 m)^3 - (4 m)^3, or (125 - 64) m^3, or
61 m^3
Answer:
(1, 0)
Step-by-step explanation:
Given the 2 equations
2x - 4y = 2 → (1)
- 4x + 6y = - 4 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
4x - 8y = 4 → (3)
Add (2) and (3) term by term
(- 4x + 4x) + (6y - 8y) = (- 4 + 4), simplifying gives
- 2y = 0 ⇒ y = 0
Substitute y = 0 in (1) or (2)
Substituting in (1) gives
2x - 0 = 2, that is
2x = 2 ( divide both sides by 2 )
x = 1
Solution is (1, 0 )
H=Hours he an skate; T=total cost
T=$7.00+($1.50/hr)H
T-$7.00=($1.50/hr)H
(T-$7.00)/($1.50/hr)=H
For T=$19:
($19.00-$7.00)/($1.50/hr)=H
$12.00/($1.50/hr)=H
8hrs=H
ANSWER: Jon can skate 8 hours for $19.00.
Hope this helps!
1200= 80%
? =100%
to find the ? you can multiply 100(1200)=120000
then 120000 divided by 80= 1500
the original price was 1500, with the discount of 20% you save 300$ and the price is 1200$
