Step-by-step explanation:

Step 1:

0.6x - 0.1 = 0.5x + 2      Equation

Step 2:

0.1x - 0.1 = 2     Subtract 0.5x on both sides

Step 3:

0.1x = 2.1     Add 0.1 on both sides

Step 4:

x = 2.1 ÷ 0.1    Divide

Please help I'll give the brainiest to the right answer!
Anna [14]

Answer:

x=1

Step-by-step explanation:

Because vertical angles are always equal, we want to solve 50x+10=70x-10.

We can add 10 to both sides to get 50x+20=70x.

We can subtract 50x from both sides to get 20=20x.

Lastly, we divide both sides by 20 to get 1=x.

So, \boxed{x=1} and we're done!

The check is left as an exercise to the reader.

Age c) The group is planning to build a fence around the garden. How many yards of fencing materials do they need for the fence?
FromTheMoon [43]

Answer:

Step-by-step explanation:

The perimeter is obtained by taking the sun of the fence :

Outer fencing :

Let's obtain b :

From Pythagoras :

b² = 15² - 12²

b = sqrt(225 - 144)

b = 9

Outer fencing = 2(12+6) + 2(8+9)

= 2(18) + 2(17)

= 36 + 34

= 70

Inner fencing :

(8 + 9 + 12 + 6 + 15 + 10) = 60

(70 + 60) = 130 yards
