Answer:
10x+5
Step-by-step explanation:
You would add 3x and 7x
you would leave 5 alone because it has no x thus it can not be added to the 3x and 7x
Answer:
This is hard to draw. on here....
But here goes:
Teammate 1:
{====} {=
Teammate 2:
{====} =
Teammate 3:
{====} =
Teammate 4:
{====} =}
So each teammate gets 1.25 or 1 1/4 of a granola bar
R + g + b = 50
r = b + 6
g = b - 4
(b + 6) + (b - 4) + b = 50
3b + 2 = 50
3b = 50 - 2
3b = 48
b = 48/3
b = 16 <=== 16 blue marbles
r = b + 6
r = 16 + 6
r = 22 <=== 22 red marbles
g = b - 4
g = 16 - 4
g = 12 <=== 12 green marbles
when the slope is perpendicular, it is the negative reciprocal
-3/5 becomes 5/3
y = mx + b
the slope is 5/3 the y intercept is -14
y = 5/3 x -14
