Answer:81
Step-by-step explanation: 9*1= 9 9*2= 18 9*3 = 27 9*4= 36 9*5=45 9*6 = 54 9*7=63 9*8= 72 9*9 81 9*10= 90
Let a and b represent the heights of the corresponding buildings (in meters).
... a = b +271 . . . . . . . a is 271 meters taller than b
... 2b -a = 211 . . . . . . if a is subtracted from twice b, the result is 211
Use the expression for a in the first equation to substitute for a in the second.
... 2b - (b+271) = 211
... b = 482 . . . . . . . . . . . simplify and add 271
... a = b +271 = 753
Building a is 753 meters tall; building b is 482 meters tall.
Can u please put the rest of the answer
Answer:
Step-by-step explanation:
A) Use the slope formula to find the slope m.
m=4/13
B) Use the point-slope formula, y−y1=m(x−x1) to find the equation of the line.
y=4/13x+198/13
C) Write in slope-intercept form, y=mx+b.
y=4/13x+198/13
The two cities are actually 427.5 miles apart.
