Answer:

Distance between the points is 8.94 units

Step-by-step explanation:

General formula:

${ \boxed{ \bf{distance = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y _{1} - y _{2} ) }^{2} } }}}$

substitute:

${ \sf{ = \sqrt{ {(5 - ( - 3))}^{2} + {(8 - 4)}^{2} } }} \\ = { \sf{ \sqrt{64 + 16} }} \\ = { \sf{ \sqrt{80} }} \\ = 8.94 \: units$

Solve for X 1. -5 = x - (-6) 2. - 30=1.25x 3. -6x=72 4. -4.9=0.7x 5. 3.15=0.45x

Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7

Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.

-5 = x - (-6)

-5=x+6

Then subtract 6 from both sides.

-5=x+6

-11=x

The answer to the second can be found simply by dividing both sides by 1.25.

- 30=1.25x

-30/1.25=1.25x/1.25

24=x

The third one can be solved by as we said before dividing both sides by -6.

-6x=72

-6x/-6=72/-6

x=-12

The fourth one can be found again by using division on both sides.

-4.9=0.7x

-4.9/0.7=0.7x/0.7

-7=x

Finally we solve the last one by again doing the same thing dividing both sides by 0.45.

3.15=0.45x

3.15/0.45=0.45x/0.45

7=x

Hope this helps!
