Answer:
x = 5 ; y = 7
Step-by-step explanation:
3x - 2y = 1 --------------------(I)
x + 4y = 33 ------------(II)
Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y
(I) 3x - 2y = 1
(II)*(-3) <u>-3x -12y = -99 </u> {Now add}
- 14y = -98
y = -98/14
y = 7
Plugin y = 7 in equation (I)
3x - 2*7 = 1
3x - 14 = 1
3x = 1 + 14
3x = 15
x = 15/3
x = 5
Answer:
h = 196/65
Step-by-step explanation:
65 miles /1 hour is the moving rate
200 miles is the distance to the railroad maker
h = ?
200- 4 miles = 196 miles were left behind the train
65miles /1 hour , 130miles/2hours , ..196miles/ ?hours
h = 196/65 = 3 hours and 1/65 minutes from an hour = 3 hours and 12/13 min.
60/ 65 = 12/13

Answer:
Lets start with d, since its all alone, take 180 - 58 = d, which is 122 = d, next c, 180 - 48 - 58 = c, which is 74 = c, next a, since d is 122, 180 - 122 = a because d + a = 180, a = 58, a + b + c = 180 so, 180 - 58 - 74 = b, b = 48
A=58
B=48
C=74
D=122
