Solve the equation. -3x + 1 + 10x = x + 4

Answers

Answer:

$x=[tex](1)/(2)$ [/tex]

Step-by-step explanation:

Solving the equation mean finding the value of x

Equation given is:

$-3x+1+10x=x+4$

Now what we need to do is take the values with x in it to the left side of the equation and the other numbers to the right side of the equation.

$-3x+10x-x=4-1$

Now simplify values with x and the numbers.

$6x=3$

$x=[tex](1)/(2)$ [/tex]

Therefore $x=[tex](1)/(2)$ [/tex]

x = $(1)/(2)$

simplify the left side by collecting like terms

7x + 1 = x + 4 ( subtract x from both sides )

6x + 1 = 4 ( subtract 1 from both sides )

6x = 3 ( divide both sides by 6 )

x = $(3)/(6)$ = $(1)/(2)$

For what side length(s) is the area of an equilateral triangle equal to 30 cm?? Only enter the number, in centimeters, rounded to two decimal places. A cm ►

Answers

Answer: The sides length are 8.32 cm

Step-by-step explanation:

An equilateral triangle has all his sides of the same lenght, so we assume that the triangle has an L lenght in his sides.

The area of a triangle is $Area = (base * height)/(2)$ where the base is L, the Area is 30 and an unknown height.

To determine the height, we cut the triangle in half and take one side. By simetry, one side has a base of $(L)/(2)$ , a hypotenuse of L and a the unknown height.

Then we apply the Pythagoras theorem, this states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, or, $hypotenuse = \sqrt{c^(2) + c^(2) }$ Where one c is $(L)/(2)$ and the other is the height.

Then we find one of the c of the equation wich will be the height.

$height = \sqrt{hypotenuse^(2)-base^(2) }$

$height = \sqrt{ L^(2) -(L)/(4) ^(2)}\nheight = \sqrt{( 3L^(2))/(4) } \n\nheight = (√(3)L )/(2)$

Finally, we use the triangle area mentioned before an find the value of L.

$30 = (L*(√(3)L )/(2) )/(2) \n\nL = \sqrt{(120)/(√(3) ) } \n\nL = 8.32 cm$

Given the equation 5(-2x -10) = 25(x + 1), solve for the value of x that will make the equation true.

Answers

Answer:

Step-by-step explanation:

5(-2x -10) = 25(x + 1)

-10x - 50 = 25x + 25

by transposing

-10x - 25x = 25 + 50

-35x = 75

x = -75/35

x = 15/7

or 2.142857..... in decimal
