If x/5+6=-14 then x equals

yanalaym [24]

Answer:

x = - 100

Step-by-step explanation:

Given

$\frac{x}{5}$ + 6 = - 14 ( subtract 6 from both sides )

$\frac{x}{5}$ = - 20

Multiply both sides by 5 to clear the fraction

x = 5 × - 20 = - 100

g100num [7]

Answer: 54 mph

Step-by-step explanation:

d-the distance

s+9 - the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so 6*(s+9)=7*s

6s+54=7s

-6s -6s

54= 7s-6s

s=54 mph

Prove that x-y = √(x+y)^2-4xy?

Svetlanka [38]

Proved Below

$\Longrightarrow x-y = \sqrt{(x+y)^2-4xy}$

$\Longrightarrow x-y = \sqrt{x^2+2(x)(y)+ y^2-4xy}$

$\Longrightarrow x-y = \sqrt{x^2+2xy-4xy+y^2}$

$\Longrightarrow x-y = \sqrt{x^2-2xy+y^2}$

$\Longrightarrow x-y = \sqrt{(x-y)^2}$

$\Longrightarrow x-y =x-y$

3/4 -3/8 in simplest form?

solmaris [256]

3/4 and 3/8 have to have equal denominators, so multiply 3/4 by 2/2 because it's equal to one, so it doesn't change the value of the fraction, but it makes the denominator (the number on the bottom) bigger.
3/4 x 2/2 = 6/8
Now subtract.
6/8 - 3/8 = 3/8
Don't subtract the denominators.
3/8 can't be simplified.
