Answer: (5,2)


Step-by-step explanation:

Given equations: 2x-2y=6......(1)\\4x+4y=28.......(2)

Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get

x-y=3......(3)\\x+y=7.......(4)

Adding equation (3) and (4), we get

2x=10\\\Rightarrow\ x=5

Substitute x=5 in equation (4), we get

y=7-5=2

Hence, the solution of the both equations is (5,2).

What are the measurements of the two angles in the figure below?
IgorC [24]

Both angles need to equal 180 degrees .

Add them together:

2x +10 + 3x-5 = 180

5X +5 = 180

Subtract 5 from each side:

5x = 175

Divide both sides by 5:

X = 175 / 5

X = 35


Now replace X with 35 in each equation:

2x +10 = 2(35) +10 = 70 +10 = 80

3x-5 = 3(35) - 5 = 105 -5 = 100


The answer is A. 80 and 100

-3 +3(n+8)= 2(1 + 6n) - 8
lilavasa [31]

Answer:

3 =n

Step-by-step explanation:

-3 +3(n+8)= 2(1 + 6n) - 8

Distribute

-3 +3n +24 = 2 +12n -8

Combine like terms

21+3n = 12n -6

Subtract 3n from each side

21+3n-3n = 12n-3n -6

21 = 9n -6

Add 6 to each side

21+6 = 9n-6+6

27 = 9n

Divide each side by 9

27/9 = 9n/9

27/9 =n

Divide the top and bottom by 3

3 =n
