\quad \huge \quad \quad \boxed{ \tt \:Answer }

  • \tt y =  90 \degree -  \cfrac{5x}{2}

____________________________________

\large \tt Solution  \: :

The two lines are parallel, henceforth we can apply Angle pair rules.

\qquad \tt \rightarrow \:(x + 3x + x) + 2y = 180

[ Co - interior angles ]

\qquad \tt \rightarrow \:5x + 2y = 180

\qquad \tt \rightarrow \:2y = 180 - 5x

\qquad \tt \rightarrow \:y =  \dfrac{180 - 5x}{2}

\qquad \tt \rightarrow \:y =  \cfrac{180 }{2}  -  \cfrac{5x}{2}

\qquad \tt \rightarrow \:y =  90 \degree -  \cfrac{5x}{2}

Answer:

y = 90 -5/2 x

Step-by-step explanation:

The angle on the left equals x+3x+x = 5x

The angle on the right equals 2y

The two angles are same side interior angles which are supplementary because the lines are parallel

5x+2y = 180

Solving for y

2y = 180-5x

Divide by 2

2y/2 = 180/2 -5x/2

y = 90 -5/2 x

Can someone help its algebra?
aalyn [17]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle , that is

3x + 2x + 6 + 6x - 3 ( simplify by collecting like terms )

= 11x + 3

Given the perimeter = 36 units , then

11x + 3 = 36 ( subtract 3 from both sides )

11x = 33 ( divide both sides by 11 )

x = 3

Then

base = 2x + 6 = 2(3) + 6 = 6 + 6 = 12 units

height = 3x = 3(3) = 9 units

hypotenuse = 6x - 3 = 6(3) - 3 = 18 - 3 = 15 units

50 w +100 is greater than or equal to 18000
Marrrta [24]
What you would do to “simplify” the equation is 18000-100 then divide by 50. The answer would be 358. Hoped this helped!

Rita is making a beaded bracelet. She has a collection of 160 blue beads, 80 gray beads, and 240 pink beads. What is the estimat
a_sh-v [17]

Step-by-step explanation:

Given that Rita is making a beaded bracelet. She has a collection of 160 blue beads, 80 gray beads, and 240 pink beads. We are to calculate the probability that Rita will need to pick atleast 5 beads before she picks a grey bead from her collection.

Prob for drawing atleast 5 beads before she picks a grey bead from her collection

= 1-Prob for drawing atleast one grey beed in the first 5 draws.

(Because these two are complementary events)

no of grey beeds drawn in first 5 trials is

Bi=(5,1/6)

Prob for drawing atleast one grey beed in the first 5 draws.

=1-Prob of no grey

Hence required prob=P(X=0 in first 5 draws)

= 0.4018

6th beeds onwards can be grey also.

Nearest answer is c)0.45
