Answer:
24d+12d=t
Step-by-step explanation:
Answer:
the answer should be x= -9 over 11
Step-by-step explanation:
The given trapezoid will have the sides ST, TV, VU, and US. Each of these can be assigned as base or legs. By this, it can be deduced that the given sides, SV and TU are the diagonals. Because the trapezoid is isosceles, the values of SV and TU should also be equal.
SV = TU
3x - 11 = x + 13
Transpose the terms with x and the constants in each sides of the equation.
3x - x = 13 + 11
2x = 24
<em> x = 12</em>
Thus, the value of x from the equation is 12.
Recall that

which means

Now,
could be positive or negative, which means
. If we specifically knew the sign of
was positive, then we can simplify and write

or if it's negative,

Let's turn this english into numbers:
<span>The time it takes Tomás to bike to the community center is 2 minutes less than half the time it takes him to bike to the city park.
Since </span>p = the time it takes Tomás to bike to the park, and it takes18 minutes to bike to the community center, the sentence turns into:
18 = 2 minutes less than half p
18 = 2 minutes less than 1/2p
18 = 1/2p-2
<span>D.1/2p–2=18
</span>
