Please help me find 'x' your help would be much appreciated <br><br><br> -Thanks
Vladimir79 [104]

Answer:

x=25.

Step-by-step explanation:

We know because of corresponding angles, the sum of the angle adjacent to (2x-5) and (2x-5) is 180 degrees

2x-5+5x+10=180

7x+5=180

7x=175

x=25

Given rectangle QUAD, If DU = 5x - 4 and QP = 2x + 7, then find the length of DU.
ira [324]

Answer:

DU = 86

Step-by-step explanation:

Properties of a rectangle,

- Opposite sides are equal in measure.

- Diagonals of a rectangle are equal.

- Diagonals bisect each other.

In the given rectangle QUAD,

Diagonals AQ and DU bisect each other at P.

AQ = DU

2(QP) = DU [Since, AQ = 2(PQ)]

2(2x + 7) = 5x - 4

4x + 14 = 5x - 4

5x - 4x = 14 + 4

x = 18

Since, DU = 5x - 4

DU = 5(18) - 4

     = 90 - 4

     = 86

Therefore, measure of DU = 86 units

X over 2 +2= 15 two step equations
Fed [463]

Answer:

\boxed{\boxed{\sf x=84}}

Step-by-step explanation:

\sf \cfrac{x}{6} +2=16

<u>Multiply both sides of the equation by 6:</u>

\sf x+12=96

<u>Subtract 12 from both sides:</u>

\sf x=96-12

<u>Subtract 12 from 96:</u>

\sf x=84
