Answer:
x = 2
Step-by-step explanation:
<em><u>1. Combine multiplied terms into a single fraction</u></em>
<em><u>19.2 − 15 = 7.5 + 8.4</u></em>
<em><u>96/5 − 15 = 7.5x + 8.4</u></em>
<u><em></em></u>
<u><em>2. Combine multiplied terms into a single fraction again</em></u>
<em><u>96/5 − 15 = 7.5x + 8.4</u></em>
<em><u>96/5 − 15 = 15x/2 + 8.4 </u></em>
<em><u /></em>
<em><u>3. Add 15 to both sides of the equation</u></em>
<u><em>96/5 − 15 = 15x/2 + 8.4 </em></u>
<u><em>96/5 − 15 + 15 = 15x/2 + 8.4 + 15</em></u>
<u><em /></u>
<u><em>4. Simplify</em></u>
- <u><em>Add the numbers</em></u>
<em> </em><u><em>96/5 = 15x/2 + 8.4 +1.5</em></u>
- <u><em>Add the numbers again</em></u>
<em> </em><u><em>96/5 = 15x/2 + 23.4</em></u>
<u><em /></u>
<u><em>5. Multiply all terms by the same value to eliminate fraction denominators</em></u>
<u><em>96/5 = 15x/2 + 23.4</em></u>
<u><em>2 x 5 x 96/5 = 2 x 5(15x/2 + 23.4)</em></u>
<u><em>7. solution</em></u>
<u><em>x=2</em></u>

Answer:
I believe its A !
Explanation:
Since one angle and one side are given, a different angle can prove that its ≅
You would be using ASA
Given:
The base is a rectangle of dimension 7 cm×6 cm.
The length of each diagonal side = 10 cm
To find the height of MT.
Formula
By Pythagoras theorem we get,
![h^{2} = l^{2} + b^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%20%3D%20l%5E%7B2%7D%20%20%2B%20b%5E%7B2%7D)
where, h be the hypotenuse
b be the base and
l be the height.
Now, in this diagram,
The perpendicular distance of M from BC = 3 cm
Slant height = 10 cm
Taking, b = 3 and h = 10 we get,
![10^{2} = l^{2} + 3^{2}](https://tex.z-dn.net/?f=10%5E%7B2%7D%20%20%3D%20l%5E%7B2%7D%20%2B%203%5E%7B2%7D)
or, ![l^{2} = 10^2-3^2](https://tex.z-dn.net/?f=l%5E%7B2%7D%20%3D%2010%5E2-3%5E2)
or, ![l = \sqrt{100-9}](https://tex.z-dn.net/?f=l%20%3D%20%5Csqrt%7B100-9%7D)
or, ![l = 9.5](https://tex.z-dn.net/?f=l%20%3D%209.5)
Hence,
The height of MT is 9.5 cm.
Answer:
136
Step-by-step explanation:
7*5=35
35+35=70
1/2*6*4=12
12+12=24
6*7=42
70+42+24=136
sorry if it is wrong.
