miss Akunina [59]

Answer:

The volume of the pyramid is $V=187\ ft^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base of the pyramid

H is the height of the pyramid

we have

$B=93.5\ ft^{2}$

$H=6\ ft$

substitute

$V=\frac{1}{3}(93.5)(6)=187\ ft^{3}$

If x/3= x+1/4, What is the value of x

olya-2409 [2.1K]

Well first because in this equation the first value is less than one, we should multiply the whole equation by 3, so
<span>x/3= x+1/4
x=3x+3/4
now we should switch the values
3x+3/4=x
now subtract x from both sides
2x+3/4=0
now subtract 3/4 from both sides
2x=-3/4
now divide both sides by 2
x=3/8
So that's your answer!

-(6x+6)+2=-6x-3 please solve

makkiz [27]

Answer:

There is no solution.

Step-by-step explanation:

To solve, use the order of operations. Follow them until you solve for x or just numbers remain.

-(6x + 6) + 2 = -6x - 3

-6x - 6 + 2 = -6x - 3

-6x - 4 = -6x - 3

-4 = -3

The answer is no solution since this is a false statement.
