Answer:
15>x*3
i don't know what you tried to say but this is what I think the answer is.
The above figure depicts :
Equation of the line:
y=mx+b
Ordinate at the origin (where the line cut the y-axis): b=1
B=(-5,5)=(xb,yb)→xb=-5, yb=5
C=(0,1)=(xc,yc)→xc=0, yc=1
m=(yc-yb)/(xc-xb)
m=(1-5)/(0-(-5))
m=(-4)/(0+5)
m=(-4)/(5)
m=-(4/5)
y=mx+b
y=-(4/5)x+1
Multiplying the equation by 5:
5[y=-(4/5)x+1]
5y=-4x+5
Adding 4x both sides of the equation:
5y+4x=-4x+5+4x
4x+5y=5
Answer: The equation for BC is: Third option 4x+5y=5
Answer:
You must drink 52 7/12 ounces or 52.58 ounces to reach the goal.
Step-by-step explanation:
Total amount of the water already drank is found by adding the fractions
So
3 1/10 ounces + 2 1/15 ounces + 6 5/20
Converting into improper fractions
31/10 + 31/15+ 125/20
Now finding the lcm of 10,15,20
so Factors of 10 = 2 x 5
Factors of 15 = 5 x 3
Factors of 20 = 2 x2 x5
LCM= 5x2x2x3= 60
31*6/60 + 31*4/60 + 125*3/60
= 186+124+375/60
= 685/60 = 11.42 ounces
The amount of water already drank is 11.42 ounces
The amount remaining is found by subtracting the amount drank from the total amount
so
64 ounces - 11.42= 52.58
It can be solved in fractions as
64- 11 5/12
Again taking making improper fraction and taking lcm
64- 137/12
= 768-137/12 = 631/12= 52 7/12 ounces
