Answer:

b. Substitution

Step-by-step explanation:

-3x-3y=3

+3x .     +3x

-3/(-3y)=(3+3x)/-3

  y= -1-x

-1-x=-5x-17

+5x .   +5x

-1+4x= -17

+1 .        +1

4/(4x)=(-16)/4

x=-4

y=-1-x

y=-1--4

y=-1+4

y=3

What is the height of a right triangle with an angle that measures 30 degrees adjacent to a base of 14
stepladder [879]

The height of the right triangle is 8.08

<h3>Calculating the height of a triangle </h3>

From the question, we are to determine the height of the described right triangle

From the given information,

The angle measure is 30 degrees adjacent to the base

and

The base is 14

Using SOH CAH TOA

Adjacent = 14

Opposite = height of the triangle

Let the height the h

∴ Opposite = h

Thus,

tan 30° = h/14

h = 14 × tan 30°

h = 8.08

Hence, the height of the right triangle is 8.08

Edward had 100 newspapers to deliver on his paper route. He had already delivered 25
kati45 [8]

Answer:

50 newspapers

Step-by-step explanation:

100 (total amount of newspapers) - 25 (amount Edward already sold) = 75 (amount of newspapers left)

75 (amount of newspapers left) ÷ 3 (Edward and his 2 friends) = 25 (equal amount each person delivered)

25 (amount Edward already sold) + 25 (amount Edward sold after his friends helped him) = 50 (amount of newspapers Edward sold in total)
