9/10=a/30. and value of a is 27
2/3x + 7 = x-7
+7 +7
---------------------
2/3x + 14 = x
-2/3x -2/3x
----------------------
14 = 1/3x
*3 *3
-------------
42 = x
Hope this helps! :)
Answer:
if you mean 17/4 tablespoons then it would take .425 tablespoons to make one cup of coffee, because 17/4 is 4.25 as a decimal.
Step-by-step explanation:
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19
