-2x = 10
x = -5
3 is the Anwser put number 3 in
Any irrational number when added to 0.4 produce an irrational sum.
Example: #0.4+pi# is irrational
Answer:
First box: y/x = 38/2 = 19
Second box: y/x = 57/3 = 19
Third box: y/x = 76/4 = 19
Constant of proportionality = 19
Equation: y = 19x
Answer:
x=4
Step-by-step explanation:
5(x-10) = 30- 15x
5x - 50= 30 - 15x
+15x +15x
20x - 50 = 30
+50 +50
20x = 80
/20 /20
x = 4
Hope this helps!
