Answer:

See below ~

Step-by-step explanation:

<u>Q3</u>

  • r = 8 / sin 45°
  • r = 8 / (1/√2)
  • <u>r = 8√2</u>

  • t  = 8 / tan 45°
  • t = 8 / 1
  • <u>t = 8</u>

<u></u>

<u>Q4</u>

  • f = 9√3 / sin 60°
  • f = 9√3 / (√3/2)
  • <u>f = 18</u>

  • o = 9√3 / tan 60°
  • o = 9√3 / √3
  • <u>o = 9</u>

#3

  • tan45=8/t
  • 1=8/t
  • t=8

Simiilary

  • cos45=8/r
  • r=8√2

#4

  • sin60=9√3/f
  • √3/2=9√3/f
  • 1/2=9/f
  • f=18

And

  • cos60=0/18
  • 1/2=0/18
  • o=18/2=9

1. What is the value of the y variable in the solution to the following system of equations?
ollegr [7]

Part 1)

we have

3x-6y=3 ------> equation A

7x-5y=-11 ------> equation B

Multiply by -7 the equation A

-7(3x-6y)=-7*3

-21x+42y=-21 ------> equation C

Multiply by 3 the equation B

3*(7x-5y)=-11*3

21x-15y=-33 -------> equation D

Adds equation C and equation D

-21x+42y=-21 \\21x-15y=-33\\---------- \\ 42y-15y=-21-33\\27y=-54 \\ y=-2

therefore

<u>the answer Part 1) is the option A </u>

y=-2

Part 2)

we have

3x+y=6

y=-3x+6 ------> equation A

6x+2y=8

Simplify Divide by 2 both sides

3x+y=4

y=-3x+4 ------> equation B

the lines A and B are parallel lines, because the slope m is equal

so

The system has no solution

therefore

<u>the answer Part 2) is the option D</u>

There is no x value as there is no solution to the system.

Part 3)

we have

4x+2y=6 ------> equation A

x-y=3

y=x-3  ------> equation B

substitute equation B in equation A

4x+2[x-3]=6

6x-6=6

6x=12

x=2

therefore

<u>the answer part 3) is the option D</u>

x=2

Part 4)

Let

x---------> The number of one-step equations

y---------> The number of two-step equations

we know that

x+y=1,120

x=1,120-y -------> equation A

3x-2y=1,300 ------> equation B

substitute equation A in equation B

3[1,120-y]-2y=1,300

3,360-5y=1,300

5y=3,360-1,300

5y=2,060

y=412

therefore

<u>the answer part 4) is  the option D</u>

y=412
