Answer:
Step-by-step explanation:
I don't exactly know what you are asking, but sum equal fractions can be 10/12 and 50/60. As long as you multiply the numerator and the denominator by the same value, you get an equal fraction.
Answer:
y= -3x+24
Step-by-step explanation:
First find the slope of the line
-x + 3y = -6
Add x to each side
3y = x-6
Divide by 3
3y/3 = 1/3 x -6/3
y = 1/3x -2
The slope is 1/3 since it is in the form y = mx+b where m is the slope
Perpendicular lines have slopes that multiply to -1
1/3 * m = -1
m = -1 * 3/1
m = -3
The slope of the perpendicular line is -3
Slope intercept form is
y = mx+b where m is the slope and b is the y interceot
y = -3x+b
We have a point ( 6,6)
6 = -3(6) +b
6 = -18+b
Add 18 to each side
6+18 = -18+b+18
24 = b
y= -3x+24
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
