120
Step-by-step explanation:
Answer: 138
Step-by-step explanation:
1/r = (3 1/2)/245
(3 1/2)r = 245
r = 245/3 1/2
r = 70
scale is 1 in to 70 miles.
Answer:
5/6
Step-by-step explanation:
5/10 + 2/6
First find the common denominator by multiplying 5/10 by 3/3
5/10*3/3=15/30
Then to get to that same denominator multiply 2/6 by 5/5
2/6*5/5=10/30
Answer:
15/30+10/30= 25/30
Then divide 25/30 by 5/5
25/30 / 5/5 = 5/6
Answer:
4
Step-by-step explanation:
we want y = mx + b
4x = 2y - 3
-2y = -4x - 3
2y = 4x - 3
therefore the gradient (slope) = the coeffecient of x, which in this case is 4
