<h3><u>Given </u><u>:</u><u>-</u></h3>
- We have given Rhombus QRST
- The measurement of two sides of rhombus that is ( 6x - 5 ) and ( 4x + 13).
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>value </u><u>of </u><u>x </u>
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>
<u>Here</u><u>, </u><u> </u><u>We </u><u>have </u>
<u>We </u><u>know </u><u>that</u><u>, </u>
- All sides of rhombus are equal
- Opposite sides of rhombus are parallel to each other
<u>Therefore</u><u>, </u>
<u>From </u><u>the </u><u>figure</u><u>, </u><u>we </u><u>can </u><u>conclude </u><u>that </u><u>:</u><u>-</u>






Hence, The value of x is 9 .
<h3><u>The </u><u>measurement </u><u>of </u><u>the </u><u>sides </u><u>of </u><u>rhombus </u><u>QRST</u><u> </u><u>:</u><u>-</u><u> </u></h3>
Length of side QR




Length of side RS




<u>From </u><u>above </u><u>we </u><u>can </u><u>say </u><u>that</u><u>, </u>
- All sides of rhombus are equal.
<h3><u>Some </u><u>more </u><u>properties </u><u>of </u><u>rhombus </u></h3>
- Opposite angles of rhombus are equal
- Diagonals of rhombus bisect each other at 90°
- Diagonals of rhombus also bisect the side angles of rhombus
- Rhombus is a quadrilateral, so the sum of interior angles of rhombus are 360°
- Whereas, The sum of the adjacent angles of rhombus are 180°.
- All rhombus are parallelogram but all parallelograms are not rhombus .
a = adult tickets
c = child
c + a = 163 tickets total
rewrite as c = 163-a
5.10c + 9.00a = 1088.70
5.10(163-a) + 9.00a = 1088.70
831.30-5.10a + 9.00a = 1088.70
831.30 +3.9a = 1088.70
3.9a = 1088.70-831.30
3.9a = 257.40
a = 257.40 / 3.9 = 66
66 adult tickets were sold
One way to solve the system is to <u>substitute</u> a variable.
<u>Explanation:</u>
One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.
The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.
Answer:
275
Step-by-step explanation:
25x15=375-15=360-85=274
Answer:
To convert something means to change (something) into a different form or so that it can be used in a different way. : to change to a different system, method, etc. : to change from one form or use to another.
