16 blocks = 4 steps
x blocks = 50 steps
(16 blocks x 50 steps)/4 steps
= 200 blocks
-a+7=2a-8
-a+a+7=2a+a-8 add a on both sides
7+8=3a-8+8 add 8 on both sides
15/3=3a/3 divide 3 on both sides
a=5 solution
Answer:
slope of AB = 2
slope CD = 2
Step-by-step explanation:
the equation of a line is y = ax+ b where a is the slope, b is the y-intercept
let us take yB - yA
→ yB - yA = axB <u>+ b</u> - axA <u>- b</u>
→ yB - yA = a(xB - xA)
→ a = (yB - yA) / (xB = xA) = (6 - 2) / (-5 - (-7)) = 2
same goes for line CD
$25.
25/5=5
5x4=20
4/5 x 25 = 20
