Answer: the shortest side is 10 centimeters.

The length of each of the other sides is 10 centimeters each.

Step-by-step explanation:

Let x represent the length of the shortest side of the triangle.

Two sides of the triangle are each twice as long as the shortest side. This means that the length of the two sides would be 2x.

The perimeter of a triangle is the sum of each side of the triangle.

The puzzle piece in the shape of a triangle has perimeter 25 centimeters. This means that

x + 2x + 2x = 25

5x = 25

x = 25/5

x = 5

The length of each of the two sides is

2x = 2 × 5 = 10

m = Miguel Indurian titles amount        l = Lance Armstrong titles amount

they both won titles to the tour de france, if we add all together, they sum up to 12 for both of them
so.. whatever "m" and "l" are, we could say that m + l = 12

now... Miguel won 2 fewer than Lance, so, whatever "l" is, m = l - 2
thus    \bf \begin{cases}
\boxed{m}=l-2\\\\
m+l=12\\
----------\\
\left( \boxed{l-2} \right)+l=12
\end{cases}

solve for "l", to see how many Lance won

how many did Miguel win? well,  m = l - 2

---------------------------------------------------------------------------------

c = mgs amount in 12oz cup of regular coffee at starbucks
d = mgs amount in 12oz cup of regular decaffeinated coffee at starbucks

we know the regular coffee cup, has 13 times more than the decaf, same 12ouncer

thus whatever "c" and "d" are, we know that c = 13d
both 12ouncers put together, yield 280mgs of caffeine

so, one could say that whatever "c" and "d" are, c + d = 280

thus      \bf \begin{cases}
\boxed{c}=13d\\\\
c+d=280\\
----------\\
\left(  \boxed{13d}\right)+d=280
\end{cases}

solve for "d" to see how much is in the decaffed cup

the regular coffee cup?  well c = 13d

CAN SOMEONE HELP WITH THIS ASAP!!!
jek_recluse [69]

Answer: x=8

Step-by-step explanation:

Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.

6x+13+4x-3=90         [combine like terms]

10x+10=90                 [subtract both sides by 10]

10x=80                       [divide both sides by 10]

x=8

Now, we know that x=8.

Upper Deck $9.25
Elena-2011 [213]

Answer:

13

Step-by-step explanation:

Purchase 2 upper deck tickets:

\$100-(2*\$9.25)=\$81.50

You can then buy 13 right field bleacher tickets before you reach deficit:

\$81.50/\$6.00=13.583

Because you cannot purchase a .583 of a ticket, the most you can buy is 13.
