Answer:

yep

Step-by-step explanation:

since a triangle's total angle is 180 degrees,

(5x + 18) + (3x + 2) + (x + 16) = 180

9x + 36 = 180

9x = 144

x = 16

m<D = (3x + 2)

m<D = 3(16) + 2

m<D = 48 + 2

m<D = 50 (your answer)

Shalnov [3]

Look at some shorter periods of time to decide whether their reasonable. Do that by simplifying the fraction. . . . . 40,000 pounds / 80 years = 4,000 pounds / 8 years = 2,000 pounds (1 ton) / 4 years = 1,000 pounds / 2 years (have you decided yet ? Well, simplify it some more) 1,000 pounds / 2 years = 500 pounds per year = almost 1 and 1/2 pounds of bread every day of your life. NOW what do you think ? Make sense ?

GrogVix [38]

The recursive formula that models the amount owed is
an = a(n-1) -75; a1 = 600.
This formula is for AFTER the first month of payment, this is why the first term is 700-100 = 600. This also means that n > 1.

PLEASEEEE HELP ME WITH THIS!!

Answer:

$x=\boxed {3.5}$

Step-by-step explanation:

Given:

AC = 5

BC = 6

DB = 4.2

∠ACD ≅ ∠BCD

AD = $x$

∵ ∠ACD ≅ ∠BCD

∴ CD is the angle Bisector of ∠ ACB

We know that, from angle bisector theorem that,

The angle bisector of an interior angle of a triangle divides the opposite side in two segments such that the two segments are proportional to the other two sides of the same triangle.

Therefore, the sides that are in proportion are given as:

$\dfrac{AC}{BC} =\dfrac{AD}{DB}$

Substituting the given values we get:

$\dfrac{5}{6} =\dfrac{x}{4.2}\\\\6x=5\times 4.2\\\\6x=21\\\\x=\dfrac{21}{6}=3.5\\\\\therefore x=3.5\ unit$

Therefore, the value of $x$ is 3.5.
