5x-3 =2x+15 <br> Someone pls help for geometry
inysia [295]

Answer:

x = 6

Step-by-step explanation:

5x-3 = 2x+15

<h3>i) move 2x to the left-hand side and change its sign</h3>

5x-2x-3 = 15

<h3>ii) move -3 to the right-hand side and change its sign</h3>

5x-2x = 15+3

<h3>iii) collect like terms</h3>

3x = 15+3

<h3>iv) add the numbers</h3>

3x = 18

<h3>v) divide both sides of the equation by 3</h3>

\frac{3x}{3}  =  \frac{18}{ 3}

x = 6

The Sum Of 3 Consecutive integers is 138, What Are The Integers?
puteri [66]

If the integers were all the same, then each one would be 1/3 of 138 = 46 .

They're not all the same, but they're consecutive, so you can find them easily.
Just start with your 3 copies of 46, take ' 1' away from one copy, and add it
to another one. You haven't changed their sum. You just made one of your
copies 1 less than 46, and you made another one of them 1 more than 46. 
Now you have 45, 46, and 47, and that sure looks like an answer to me.
Isn't that easy ... you only had to use some brain instead of a lot of messy
algebra.  That's what 'Brainly' might be all about, I guess.

Given that P = (-5, 5) and Q = (-13, 10), find the component form and magnitude of 2 vector PQ.
Brut [27]
Define unit vectors along the x-axis and the y-axis as \hat{i} , \, \hat{j} respectively.

Then the vector from P to Q is
\vec{PQ} = (-13+5)\hat{i} + (10-5)\hat{j} = -8\hat{i} + 5\hat{j}
In component form, the vector PQ is (-8,5).

The magnitude of vector PQ is
√[(-8)² + 5²] = √(89) = 9.434

Answer:
The vector PQ is (-8, 5) and its magnitude is √89  (or 9.434).
