L = Lower box tickets amount.
U = Upper box tickets amount.
we know the whole amount sold were 254 of both, thus
L + U = 254.
since we know the price of L is 12.5 for each, then the amount of money sold total for all of them has to be 12.5 * L, or
12.5L.
and the U is 10, so its total amount of money for it is
10U.
we also know that the total amount for both spent was 2745, thus
12.5L + 10U = 2745.
so, 172 Upper box tickets were sold then.
how many Lower box tickets were sold? well,
L = 254 - U
Answer:
the first one
Step-by-step explanation:
give me a brainley
Let’s say son’s age = S
Dad’s age = D
4 years ago, the son was (S-4) and dad now is three times that so D=3(S-4)
Expand that to get D=3S-12
In 12 years, the son will be (S + 12)
Dad will also be (D + 12) and he will be two times the sons age at that point so:
D + 12 = 2(S + 12)
Expand the right side:
D +12 = 2S + 24
Subtract 12 from both sides:
D = 2S + 12
So now D = 2S + 12 AND
D = 3S - 12
Since both equations equal “D”, they must then equal each other:
2S + 12 = 3S - 12
Do some algebra and you get S = 24
Plug this back into EITHER “D=“ equations to find D
D=2(24) +12
D=60
Answer:
26.2 cm2
Step-by-step explanation:
120=360*1/3 >> This sector is 1/3 of a circle.
The area of a circle is 5*5*3.14=78.5
So 1/3 of it is 78.5*1/3=26.16=>26.2
Take out the gcf (5).
5(x+3)
The inner binomial cannot be factored.
Final answer: 5(x+3)
