Given the median line QR and trapezoid MNOP, what is the value of x? MN=17 QR=x+12 OP=5x-14
kari74 [83]
<u><em>Answer:</em></u>
x = 7
MN (first base) = 17 units
OP (second base) = 21 units
QR (median) = 19 units

<u><em>Explanation:</em></u>
In a trapezium, the length of the median is equal to half the sum of the two bases.

<u>From the given, we have:</u>
MN (first base) = 17 units
OP (second base) = 5x - 14 units
QR (median) = x + 12 units

<u>Applying the above rule:</u>
median = 0.5 (first base + second base)
x + 12 = 0.5 (17+5x-14)
2(x+12) = 17+5x-14
2x + 24 = 3 + 5x
24-3 = 5x-2x
21 = 3x
x = \frac{21}{3}
x = 7

<u>Based on the above, the lengths would be:</u>
MN (first base) = 17 units
OP (second base) = 5x - 14 = 5(7) - 14 = 21 units
QR (median) = x + 12 = 7 + 12 = 19 units

Hope this helps :)

Solve the system: 5x+6y=−20 9y+2x=25
Semmy [17]

Answer:

  (x, y) = (-10, 5)

Step-by-step explanation:

This one can be a little tricky because the variables in the equations are not in the same order. It might help to rewrite the system as ...

  • 5x +6y = -20
  • 2x +9y = 25

Multiplying the first equation by 3 and subtracting 2 times the second equation can eliminate the y-variable:

  3(5x +6y) -2(2x +9y) = 3(-20) -2(25)

  11x = -110 . . . . . . simplify

  x = -10 . . . . . . . . divide by 11

  5(-10) +6y = -20 . . . substitute for x in the first equation

  6y = 30 . . . . . . . . add 50

  y = 5 . . . . . . . . . . divide by 6

The solution is (x, y) = (-10, 5).

The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of X.​
uranmaximum [27]

Answer:

1). x° + 100° + 120° + 100° = 360°

2). x = 40

Step-by-step explanation:

Formula for the sum of the interior angles of a polygon = (n-2)\times 180

Where n = number of sides of the polygon

From the picture attached,

For n = 4,

Sum of the interior angles of the given polygon = (4 - 2) × 180°

                                                                                = 360°

Therefore, equation for the sum of interior angles will be,

x° + 100° + 120° + 100° = 360°

x° + 320° = 360°

x° = 360° - 320°

x° = 40°

Which is the best for the sum 2/9+10/11?a. 0+0=0 b.1/2+1/2=1 c. 1+1=2d. 0+1=1
Sloan [31]

You have the following expression:

\frac{2}{9}+\frac{10}{11}

By definition, when you want to express a fraction as a decimal number, you must divide the numerator by the denominator. Knowing this, you get the following:

\begin{gathered} \frac{2}{9}\approx0.22 \\  \\ \frac{10}{11}\approx0.90 \end{gathered}

You can identify that:

\begin{gathered} 0.22\approx0 \\ 0.90\approx1 \end{gathered}

Based on the above, you can determine that the best estimate for the sum is:

\frac{2}{9}+\frac{10}{11}\approx0+1=1

The answer is option d:

0+1=1
