Answer:
4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 8y from both sides.
Step 3: Subtract 18 from both sides.
Step 4: Divide both sides by -9.
y=4
I’m not sure if I did my math correct but I got 1x
I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x
10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46
This is all I know sorry. Hope you find some more help :)
Answer:
$40
Step-by-step explanation:
we know that
The linear equation in slope intercept form i equal to
where
y is the amount of her mother's donation
x is the number of miles that Melissa walks
where
m is the slope
b is the y-intercept
In this problem
The slope is
The y-intercept is
substitute
so
For x=15 miles
substitute
