I believe "BY || JE" means that those two lines are congruent, which means the slope of JE would be the same as the slope of BY. So in this case the answer should be B. -1/5.
I hope this helped.
Answer: 12
Step-by-step explanation:
(55-52) + ( 3 +6)
3 + 9
12
Step 1: Simplify both sides of the equation.
3(x−5)−5=23
(3)(x)+(3)(−5)+−5=23(Distribute)
3x+−15+−5=23
(3x)+(−15+−5)=23(Combine Like Terms)
3x+−20=23
3x−20=23
Step 2: Add 20 to both sides.
3x−20+20=23+20
3x=43
Step 3: Divide both sides by 3.
3x
/3 = 43

Answer:
50 kg water.
Step-by-step explanation:
We have been given that the number of kilograms of water in a human body varies directly as the mass of the body.
We know that two directly proportional quantities are in form 
, where y varies directly with x and k is constant of variation.
We are told that an 87-kg person contains 58 kg of water. We can represent this information in an equation as:
Let us find the constant of variation as:
The equation 
represents the relation between water (y) in a human body with respect to mass of the body (x).
To find the amount of water in a 75-kg person, we will substitute 
in our given equation and solve for y.
Therefore, there are 50 kg of water in a 75-kg person.
Answer:
fraction 1 and 3 over 5
Step-by-step explanation:
2:3 is equal to 8 blocks
5:12 is equal to 5 blocks
if you divide them, the result is:
8/5 which is the same as 1 3/5
because 5 is contained 1 time in 8 and the rest is 3
