Solve the following inequality. 36> -2(x+4)+14

Answers

Answer:

x > - 15

Step-by-step explanation:

Given

36 > - 2(x + 4) + 14 ← distribute and simplify right side

36 > - 2x - 8 + 14

36 > - 2x + 6 ( add 2x to both sides )

2x + 36 > 6 ( subtract 36 from both sides )

2x > - 30 ( divide both sides by 2 )

x > - 15

solve the equation


2(h-8) - h=h - 16

A h = 8

B h= -8

C h = infinitely many solutions

D h = no solution

Answers

Answer:

2(h-8)-h=h-16

2(h-8)=h+h-16

2(h-8)=2h-16

2(h-8)=2(h-8)

h-8=h-8

h-h=8-8

0=0 so their can be infinite value of h.

hence c is correct

we can put in place of anything but answer will be zero.

Answer:

C h= infinitely many solutions

Step-by-step explanation:

when you replace h with any number it is true

say h= 3

2(3-8) - h = h-16

2(-5) - 3 = 3 - 16

-10 - 3 = -13

-13 = -13

using distributive property:

2h-16-h = h-16

combine like terms

h-16=h-16

it is the same expression on both sides of the equal sign

Two given angles cannot be both..


A. congruent and complementary

B. vertical and congruent

C. adjacent and congruent

D. vertical and adjacent


Please help me :(

Answers

The right answer is congruent and complementary because they both are different from each other and different causes

If vertical angles are directly opposite each other and do not share a common side, therefore, two given angles cannot be both: D. vertical and adjacent.

Recall:

If two angles are said to be vertical when both angles are directly opposite each other and are also congruent or equal in measure.

Vertical angles share a common vertex or point but do not share a common side.

Adjacent angles share a vertex and a common side.

Thus, if vertical angles are directly opposite each other and do not share a common side, therefore, two given angles cannot be both: D. vertical and adjacent.

Find the missing length marked with a question mark.
UVW-USR

Answers

Given:

[tex]\Delta UVW\sim \Delta USR[/tex]

To find:

The missing length marked with a question mark.

Solution:

Let x be the missing value.

We have,

[tex]\Delta UVW\sim \Delta USR[/tex]

Corresponding sides of similar triangles are proportional, so

[tex]\dfrac{UV}{US}=\dfrac{VW}{SR}=\dfrac{UW}{UR}[/tex]

Using this, we get

[tex]\dfrac{UV}{US}=\dfrac{UW}{UR}[/tex]

On substituting the values, we get

[tex]\dfrac{70}{x}=\dfrac{55}{44}[/tex]

[tex]\dfrac{70}{x}=\dfrac{5}{4}[/tex]

On cross multiplication, we get

[tex]70\times 4=5\times x[/tex]

[tex]280=5x[/tex]

[tex]\dfrac{280}{5}=x[/tex]

[tex]56=x[/tex]

Therefore, the missing length is 56 units.

What number goes in the “?”

? - 2x - 5 = 5

Answers

First, replace the “?” with an x:
x - 2x - 5 = 5

Next, combine alike terms:
[ x - 2x ] - 5 = 5
^ alike terms

This will result in:
-x - 5 = 5

You do the inverse (opposite) of -5
-x -5 = 5
+5

Once you do the plus 5, the five moves to the end of the equation:
-x - 5 = 5 + 5
+5>>>>>^

The “-5” no longer exists because you canceled it with the “+5” that you moved to the other side.
The new equation:
-x = [5 + 5]
^ you add these two

After adding you get:
-x = 10

When putting “x” into a number it will ALWAYS be 1.

You then divide both sides by the “x” (which is -1 since it it always equal to one but is negative because it has a negative sign on it)

Your new equation:
-x / -1 = 10 / -1

If you divide to negatives, this will result in a positive.

You’re left with:
-x / -1 = x (since two negatives become a positive result)
10 / -1 = 10 (if there’s a negative and positive when dividing, it will automatically become negative) [ONLY FOR DIVISION]

At the end you’re left with:
x = -10
