Answer:

One = 3x = 3 x 18 = 54

Second = 7x = 7 x 18 = 126

Step-by-step explanation:

3x+7x = 180

10x = 180

x = 180/10 = 18

One = 3x = 3 x 18 = 54

Second = 7x = 7 x 18 = 126

I hope im right!

F(x)=3/x+2-√x-3 f(7)=

Paladinen [302]

Divide each term by x and simplify.

(Ok so I don’t make it confusing the first part after “F=“ will be on top The I’ll put the bottom part below oh btw the top and bottom r negative so put the negative sign in front of the fraction)

F= - 21fx+x√x-2x-3(top of fraction)

F=-x^2(bottom of fraction)

Just use the distributing property and combine like terms. There isn’t a definite answer since it is an expression.

Value of x for 12(x-2)+3x=1/2(x+6)+2

Damm [24]

Answer:

The value of x = 2

Step-by-step explanation:

Given the equation

$12\left(x-2\right)+3x=\frac{1}{2}\left(x+6\right)+2$

Expand 12(x-2) = 12x - 24

Expand 1/2(x+6) = 1/2x + 3

so the equation becomes

$12x-24+3x=\frac{1}{2}x+3+2$

simplifying

$15x-24=\frac{1}{2}x+5$

$15x=\frac{1}{2}x+29$

multiplying both sides by 2

$30x = x + 58$

subtracting x from both sides

$30x - x = 58 - x$

$29x = 58$

divide both sides by 29

$\frac{29x}{29}=\frac{58}{29}$

simplifying

$x = 2$

Therefore, the value of x = 2
