If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side

Soloha48 [4]

Answer:

$x=9, AB=BC=AC=35$

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that $AB=BC=AC$ . We are given the lengths of all 3 sides in terms of $x$ , but we only need to set two of them equal to each other to solve for $x$ . Let's use $AB$ and $BC$ to solve for $x$ . We know that $AB=BC$ , $AB=2x+17$ , and $BC=6x-19$ . Therefore, we can write the following equation to solve for

$AB=BC\\2x+17=6x-19$ (Substitute given values into equation)

Solving for $x$ , we get:

$2x+17=6x-19\\2x+17-17=6x-19-17$ (Subtract $17$ from both sides of the equation to isolate constants)

$2x=6x-36$ (Simplify)

$2x-6x=6x-36-6x$ (Subtract $6x$ from both sides of the equation to isolate $x$ )

$-4x=-36$ (Simplify)

$\frac{-4x}{-4}=\frac{-36}{-4}$ (Divide both sides of the equation by $-4$ to get rid of $x$ 's coefficient)

$x=9$ (Simplify)

Therefore, $AB=2x+17=2*9+17=18+17=35$ , and $AB=BC=AC=35$ . Hope this helps!

The Nutty Professor sells cashews for $7.10 per pound and Brazil nuts for $4.60 per pound. How much of each type should be used

aivan3 [116]

Answer:

Pounds for cashew- 20.96

Pounds for Brazilian nut- 11.04

Step-by-step explanation:

Let c be the pounds of cashew

Let b ne the pound of Brazilian but

32×6.24

= 199.68

7.1c + 4.60b= 199.68.......equation 1

c + b= 32..........equation 2

From equation 2

c= 32-b

Sub 32-b for c in equation 1

7.1(32-b) + 4.60b= 199.68

227.3-7.1b+4.60b, = 199.68

227.3-2.5b= 199.68

-2.5b= 199.69-227.3

- 2.5b= -27.61

b= 27.61/2.5

b= 11.04

Sub 11.04 for b in equation 2

c+b= 32

c + 11.04= 32

c= 32-11.04

c= 20.96
