X + 20 is greater than 4x -1
Paul [167]

Answer:

False; they are equal.

Step-by-step explanation:

The equation is x + 20 > 4x - 1.

First, do the opposite of -1 and add one to the other side while -1+1 cancels out. Now it's x+21 > 4x. Now subtract x from both sides. Positive x minus negative x cancels out and 4x minus x or 1x is 3x. Now you're left with 21> 3x. Now do the inverse operation of multiplication and divide both sides by 3. Now the 3x over 3 cancels out and 21 divided by 3 is 7. So x is 7. If you substitute it in. It will be 7+20 which is 27 which is great than 4(7)-1 which is 28-1. 28-1 is 27. So, the equation is false. They are equal.

Can someone please help!
vekshin1

Answer:

<h2>43.3cm²</h2>

Step-by-step explanation:

Area of a Triangle = Base * Height * 1/2

Base = 5

Height = 4.33

Area of a Triangle = 5 * 4.33 * 1/2

Area of a Triangle = 10.825

There are four triangles.

Surface Area = Area of a Triangle * Number of Triangles

Surface Area = 10.825 * 4

Surface Area = 43.3cm²

Solve this inequality for x: -46 − 8x &gt; 22. A. x &lt; 8.5 B. x &lt; -8.5 C. x &gt; -8.5 D. x &gt; 8.5
marissa [1.9K]

Step one rewrite: -46-8x>22

Add 46 to both sides: -8x>68

Divide both sides by -8 to isolate x<-8.5

(remember to flip the inequality sign when multiplying or dividing by negative numbers in inequality problems)

So the correct answer is B. x < -8.5
