We must create a number line and draw an arrow for each term of the sum.
The procedure is now described:
1) Create a number line with big marks for each unit and small marks for each tenth.
2) Draw an arrow from 0 to 4.2. (Blue arrow in the figure)
3) Create an arrow from 4.2 to 3.8. (Green arrow in the figure)

8x-4=2(4x-4) math question I need the answer to pls help
Answer:
no solutions.
8x-4=2(4x-4)
distribute.
8x-4 = 2*4x+2*-4
8x-4=8x-8
add 4 to both sides
8x= 8x - 4
subtract 8x from both sides
0=-4
this has no solutions, since 0 is not equal to -4.

Answer:
3x – 2 = 76 (Alternate Interior Angles)
3x = 76 + 2
3x = 78
x= 26°.
x + 2 = 40 (Alternate Interior angles).
x = 40 - 2
x= 38

The ratio of the amount of money Karen had to the amount of money Peter had was 2 : 5. After Peter received $75 from his mother, the ratio of the amount of money Karen had to the amount of money Peter had became 4 : 15. How much money did each person have at first?
Answer:
$60 and $150
Step-by-step explanation:
Initially
Karen : Peter = 2 : 5
After Peter receiving $75 the ratio is
4 : 15
We can suppose that initally the amount of monye Karen has is 2x and Peter is 5x.
The new ratio is
2x : (5x +75) = 4 :15
2x (15)= 4 (5x +75)
30 x = 20 x + 300
10 x = 300
x = 30
So at first Karen has 2x =60 dollars while Peter has 5x = 5(3) = 150 dollars.
