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!

You are buying 12-packs of Mountain Dew for $\text{4.50}4.50 each and have a gift card worth $77. The function m\left(x\right)=4

poizon [28]

Answer:

$191

Step-by-step explanation:

The function is given by :

m(x) = 4.50x-7 ...(1)

Where

m(x) is the total cost if you buy x 12 packs of Mountain Dew.

We need to find the cost you pay to buy 44 12-packs of Mountain Dew

Put x = 44 in equation (1), we get :

m(x) = 4.50(44)-7

m(x) = 198-7

m(x) = $191

Hene, the cost for 44 12- packs of Mountain Dew is $191.
