Which value of x is in the solution set of 2(3x-1)≥4x-6

densk [106]

_ means equal to

2(3x-1)>_ 4x-6
6x-2>_4x-6
6x - 4x >_-6+2
2x>_ -4
=> x >_ -4/2
=> x >_ -2
This means x is greater or equal to -2 .
X - [-2, infinity)

Solve the system of linear equations by elimination x + 3y = 5 2x - 3y = 1

enot [183]

x + 3y = 5
2x - 3y = 1
------------------add
3x = 6
x = 2

x + 3y = 5
2 + 3y = 5
3y = 3
y = 1

answer x = 2 y = 1

You must use the substitution method. 3x+2y=11 y=5x-1

valina [46]

Plug in y=5x-1 for y in 3x+2y=11

3x+2(5x-1)=11
3x+10x-2=11
13x=13
x=1

plug x=1 to y=5x-1 to find y

y=5(1)-1
y=5-1
y=4

ANSWER: x=1 and y=4 which is (1,4) as an ordered pair

The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gether with a half circle at each

klasskru [66]

Answer:

398.21 m

Step-by-step explanation:

The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gather with a half circle at each end.

So, the radius of each half circle will be $\frac{73}{2} = 36.5$ m.

Therefore, the total distance around the track i.e perimeter of the area covered by the track will be = 2 × Perimeter of each half circle + 2 × Length of the rectangle.

= Perimeter of full circle + 2 × Length of the rectangle.

= $2\pi r + 2l$

= $\frac{2 \times 22 \times 36.5}{7} +2 \times 84.39$

= 398.21 m.(Answer)
