I need to know if these answers are correct or not...
1.
x + (x + 1) + (x + 2) + (x + 3) = 70
4x + 6 = 70
4x = 70 - 6
4x = 64
64/4 =
x = 16
16 + 17 + 18 + 19 = 70
10.
Sca = 336/12 = 28 miles/hr
Scu = 336/14 = 24 miles/hr ->
28 = B + C
24 = B - C ->
28= B + C -> B = 28 - C -> 24 = B - C
-> 24 = 28 - C - C
24 -28 = -2C
-4 = -2C
C = 2 -> B = 28 - 2
= 26 miles/hr
