Yes
15+14 > 19 true
15+19 > 14 true
14+19 > 15 true
If all the statements are true then it’s a right triangle.
2 - 2/3x = 3/7 (Multiply by 21, the lowest common factor)
42 - 14x =9
A is wrong.
The hight and age are sometimes not proportional or ideal. Some kids don't develop due to health problems for example, which make them look smaller than normal. Other people might a conditions, which makes them grow to tall.
Hope it helped,
Happy homework/ study/ exam!
The x int is 0,6
The y int is -3,0
Hi!
<h3>We need to isolate x on one sides, and whatever we do to the equation we have to do on both sides. </h3><h3>Subtract 5 from both sides. </h3>
4x + 5 - 5 = 12 - 5 - 7x
4x = 7 - 7x
<h3>Add 7x to both sides. </h3>
4x + 7x = 7 - 7x + 7x
11x = 7
<h3>Divide by 11 on both sides</h3>
11x/11 = 7/11
<u>x = 7/11</u>
<h2>The answer is x = 7/11</h2>
Hope this helps! :)
