Answer:
y = -12
Step-by-step explanation:
-7/3y - 2/9 = 1/3
cross multiple for 1/3:
-21/3y - 6/9 = 1
cross multiply for 3y and 9:
-21 - 6 = 3y + 9
3y + 9 = -27
3y = -36
y = -12
P(boy's name) = 16/30 = 0.53 (the three's continuous) = 53.3%
Answer:
x = -1
Step-by-step explanation:
First, add x to both sides.
-2x-6-x+x=-x-4x-8+x
-----------------------------------
Next, Refine it.
-2x - 6 = -4x - 8
--------------------------------------
Now, add 6 to both sides.
-2x - 6 + 6 = -4x - 8 + 6
--------------------------------------
Now we Simplify.
-2x = -4x - 2
---------------------------------------
Add 4x to both sides.
-2x + 4x = -4x - 2 + 4x
----------------------------------------
Simplify again.
2x = -2
-----------------------------------------
Divide both sides by 2.
2x/2 = -2/2
------------------------------------------
And we're almost finish! Just need to simplify.
x = -1.
Answer:
Step-by-step explanation:
you set the equation and try to bring it over one
i will do one of them for you
$9.40 for 5 cans of soup
to find what one can costs, divide 9.40 by 5
and you get $1.88
or you can set a proportion
9.40 x
--------- = ----------
5 1
cross multiple
5x=9.40
x=1.88
Answer:
Option A. (-16,14)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
In this problem we have that
so
--->
--->
therefore
The coordinates of point Q are (-16,14)
