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.

(2x-14)=100
2x=100+14
2x=114

In the drawing below, a boy with his shadow is standing beside a monument with its shadow. the drawing is not drawn to scale.
CaHeK987 [17]
There exists the same question from other source that has the image of the drawing. Attached to this answer is the image.

To solve this, first we have to assume ratios.

Real Height / Shadow = 56 / 49
Real Height / 28 = 56 / 49
49 * h = 56 * 28
49h = 1568

Then, we have to divide both sides by 9
h = 32

Therefore, the obelisk is 32 ft

C is correct answer to this question.
