The answer is: B. (If you subtract 11.4 - 6.8, you get 4.6. B is the only answer that shows this.) While all of the answers show mental math, only B gives you the correct answer.
Answer:
a+b=5/2a, a+b=5/3b
Step-by-step explanation:
1.2a=0.8b
6/5a=4/5b
6a=4b
b=3/2a, a=2/3b
a+b=3/2a+a
a+b=5/2a
a+b=2/3b+b=5/3b
Answer: 31
Step-by-step explanation: divide 558 by 18
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 3 (x + 4) ← is in point- slope form
with slope m = 3
The diagonals of a square are perpendicular to each other.
Given a line with slope m then the slope of a line perpendicular to it is
= -
= - 
Thus the slope of FH is -
