Answer:
37.854
Step-by-step explanation:
59.73-21.876=37.854
Cost of month plan = $40
Cost of minutes used = $0.45 after 700 minutes
Total cost = $48.10
Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)
------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
0.45x = 48.10 + 275
0.45x = 323.10
x = 323.10 ÷ 0.45
x = 718

Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23
Answer:
84% or 21/25
Step-by-step explanation:
1 is 8, 2 is 6, 3 is 9, 4 is 11, 5 is 9, 6 is 7. add the values: We get 50.
because landing on 1 is an 8/50 chance, not landing on one is a 42/50 chance, which in turn is 84% or 21/25.
