Is -7 + 9= 9 + 7 true, false or open

2 answers:

6 0

$-7 + 9 \neq 9 + 7$

$2 \neq 17$

When you add a positive number and a negative number, you get a positive, but the number is smaller. If you add two positive numbers, then of course, you're going to get a positive number as an answer. But overall, this is false.

Can you solve 4 + 2/3 x = -5 in fraction form?

guapka [62]

Answer:

$\frac{-27}{2} = (-13)(\frac{1}{2})$

Step-by-step explanation:

The given equation is 4 + 2/3 x = -5

Taking variable on one side and constants on other side, we get

$-9 = (\frac{2}{3})(x)$

$x = (\frac{3}{2})(-9) = \frac{-27}{2} = (-13)(\frac{1}{2}) = -13.5$

The number in decimal form is given by -13.5

The number in fraction form is given as $\frac{-27}{2} = (-13)(\frac{1}{2})$

How to master Euclidean geometry

Roman55 [17]

Euclidean geometry is all about shapes, lines, and angles and how they interact with each other. There is a lot of work that must be done in the beginning to learn the language of geometry. Once you have learned the basic postulates and the properties of all the shapes and lines, you can begin to use this information to solve geometry problems. Unfortunately, geometry takes time, but if you put in the effort, you can understand it.
