Let's go:


\frac{80}{2x + 80} = \frac{60}{87} \\\\ 60.(2x + 80) = 80.87 \\\ 120x + 4800 = 6960 \\\ 120x = 6960 - 4800 \\\ 120x = 2160 \\\ x = 18


I hope I helped you.

Considering the least common multiple of the denominators, it is found that the result of the expression is given by:

\frac{9100}{138320}

<h3>How do we add fractions?</h3>

We place all the terms of the addition in "equivalent" fractions, with the same denominator, found from the last common multiple of all the denominators.

In this problem, the denominators are as follows: 28, 70, 130, 208, 304. Using a calculator, their lcm is of 138,320.

Considering equivalent fractions(the numerators are the division of the lcm by the previous denominator), the expression is:

\frac{4940}{138320} + \frac{1976}{138320} + \frac{1064}{138320} + \frac{665}{138320} + \frac{455}{138320} = \frac{4940 + 1976 + 1064 + 665 + 455}{138320} = \frac{9100}{138320}

N=3
Distribute them at the numbers, add 30 to both sides of the equation then simplify. Then add 14 to both sides of the equation. Simplify again. Divide both sides of the equation by the same factor. Simplify. Answer is n=3

Which angle determines whether or not quadrilateral SVUT is a trapezoid? What measure would the angle need to be for SVUT to be
Lorico [155]

Answer:  The answer is ∠TUV.

Step-by-step explanation: Given in the question a quadrilateral SVUT with ∠SVU = 112°. We need to determine the angle whose measure will decide whether or not the quadrilateral SVUT is a trapezoid.

We know that for a quadrilateral to be a trapezoid, we need only one condition that one pair of opposite sides must be parallel.

So, in quadrilateral SVUT, since the measure of  ∠SVU is given, so we can decide  it is a trapezoid or not if we know the measure of ∠TUV. As ST and UV cannot be parallel, so its meaningless to determine ∠TSV.

For SV and TU to be parallel to each other, we need

∠SVU + ∠TUV = 180° (sum of interior alternate angles).

Therefore,

∠TUV = 180° - 112° = 68°.

Thus, we need to determine ∠TUV and its measure shoul be 68°.
