Answer:

AC ≈ 7.8 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A (- 4, - 4 ) and (x₂, y₂ ) = C (2, 1 )

AC = \sqrt{(2-(-4))^2+(1-(-4))^2}

      = \sqrt{(2+4)^2+(1+4)^2}

      = \sqrt{6^2+5^2}

     = \sqrt{36+25}

     = \sqrt{61}

     ≈ 7.8 ( to 1 dec. place )

When 2/3 of a number is increased by 20, the sum is then halved, the result obtained is the same as 2/3 of the number, increased
aleksklad [387]

\frac{2/3x+20}{2} =\frac{2}{3} x+3\\\frac{2/3x+20}{2} - 3 = \frac{2}{3}x\\\frac{2/3x+20}{2} - \frac{6}{2} = \frac{2}{3}x\\\frac{2/3x+20-6}{2} = \frac{2}{3}x\\\frac{2/3x+14}{2} = \frac{2}{3}x\\2(\frac{2/3x+14}{2}) = 2(\frac{2}{3}x)\\2/3x+14=\frac{4}{3}x\\14=\frac{4}{3}x-\frac{2}{3}x\\14=\frac{2}{3}x\\\frac{14}{1}/\frac{2}{3}=x\\\frac{14}{1}*\frac{3}{2}=x\\7*3=x\\x=21

The number is 21.

Help anyone<br> 8th grade math?
Kruka [31]

Answer: x = 1

Step-by-step explanation:

2.8 + 2x = 0.6 x 8

2.8 x + 2x = 4.8

2x = 4.8 - 2.8 (subtract 2.8 on both sides)

2x = 2

x = 1 (divide 2 on both sides)

Hope this helps
