Find the distance between the points (8,10) and (4,7)
r-ruslan [8.4K]

Answer: 7 is the distance in between the points

Step-by-step explanation: How you find the distance between points is pretty simple once you know how to do it!

So first take your X coordinate take the first one (8) and subtract it from the second one (4) 8-4=4 so now we have 4 put that aside for a moment,

Now take your Y coordinate subtract the first one (10) from the second one (7), 10-7=3

Finally add the 3 and 4 together you get 7 that is why 7 is the distance in between the points

If you need further help or instruction please let me know!

Translate each verbal expression into an algebraic equation and solve
Gekata [30.6K]

Step-by-step explanation:

I think this might be correct you can see for yourself if you think this is good

solution: 5 packs

let a be plates and b be packs

100a = 5b

= (20*5)a

sorry if confusing I'll say it here

packs is 20 plates and you need 100 plates

just divide the plates you need (100) and the plates per pack (20) and that's how many packs you need to get(5)

Pic included What is value of x? Enter your answer in the box. x =
Elza [17]

Answer:

The answer to your question is x = 10

Step-by-step explanation:

Use proportions to solve this problem

Given                  (x + 4)/8 = (2x + 1)/12

                          12(x + 4) = 8(2x + 1)

Expand

                          12x + 48 = 16x + 8

Group like terms

                           12x - 16x = - 48 + 8

Simplify

                          -4x = -40

Solve for x

                              x = -40/-4

Result

                              x = 10
