EASY PLZ HELP! Solve for x. (Show your work) 2x + 3 > 5

m_a_m_a [10]

Hi there!

Answer:

X>1

*The answer must have a positive sign and greater than symbol.*

Step-by-step explanation:

First, you subtract by 3 from both sides of an equation.

$2x+3-3>5-3$

Then, you subtract by the numbers from left to right.

$5-3=2$

$2x>2$

You can also divide by 2 from both sides of an equation.

$\frac{2x}{2}>\frac{2}{2}$

Finally, you divide by the numbers from left to right.

$2/2=1$

Final answer is x>1

I hope this helps you!

Have a nice day! :)

Thank you so much! :)

Identifying Possible Triangles

Masja [62]

Answer:

3rd triangle can be constructed with dimensions 2,6,7.

Step-by-step explanation:

sum of any two sides > third side.

difference of any two sides < third side

8+5=13 not >14 (no triangle.)

7+8=15 not >15 (no triangle)

2+6=8>7

2+7=9>6

7+6=13>2

7-2=5<6

7-6=1<2

6-2=4<7

so it is a triangle.

6+3=9 not >10 (not a triangle)

Step-by-step explanation:

Using the formular, Sn = n/2(2a + (n - 1)d)

where, n = 6: Sn = 6/2( -20 + 5(3)) = 3(15 - 20)

∴ Sn = 15
