Answer:
86
Step-by-step explanation:
82+90=172
172/2 (divided by two because thats how many numbers we added up to get 172)
172/2=86
86 is your answer
M=2
The slope intercept form is y=Mx+b,where m is the slope and b is the y intercept y=Mx+b
Using the slope intercept form the slope is 2 m=2
All lines that are parallel to y =2x-5 have the same slope of 2
M=2
Answer:
-6/5
Step-by-step explanation:
Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
Answer:
below
Step-by-step explanation:
I would guess that they added 42 and 45 and then added 1 for their mistake. That might be a bit of stretch, but that is what I think
In the proportional theory,
28 units is the total measurement that includes 8 units.
So, 10 + 3x - 5 is the total measurement that includes 10 units proportionally.
This means,
28 = 10 + 3x - 5
Now solve for x,
28 = 10 + 3x - 5
28 - 10 = 3x - 5
18 + 5 = 3x
23 = 3x
23 / 3 = x
So x = 23/3 or 7.6666....
