Answer:
y= -x/6-9
x= -6y-54
Step-by-step explanation:
Answer: 4
Step-by-step exzplanation: 20/360= X/72
360X= 1440
Divide by 360
X=4
Answer:
Speed of a= 21 miles/hr
r = Speed of b= 7 miles/hr
Speed of a = 3r
Step-by-step explanation:
The cyclist are 112 miles apart
Time traveled by two = 4 hours
Speed of a = 3 * speed of b
If a cylcles 3 times More than b, then a will cover 3*distance of b
But speed = distance/time
Time = 4hours
Total distance=112
a = 3b
3b + b = 112
4b = 112
b = 112/4
b = 28 miles
a = 3b
a = 3*28
a = 84 Miles
They bought traveled 4 hours
Speed of a = 84miles/4 hours
Speed of a= 21 miles/hr
Speed of b = 28miles/4 hours
Speed of b = 7 miles/hr
Answer:
this is the answer
Step-by-step explanation:
hope it helped!!!
X = 42
x/3 - 4 = 10
+ 4 +4
x/3 = 14
•3 •3
x = 42
