Answer:
the answer is she had $4.40 left.
Step-by-step explanation:
1) 40x1.50=<u>60</u> 2) 40x0.89= <u>35.6</u> 3) 60+35.6= <u>95.6</u> 4) 100- 95.6= <u>$4.4</u> I hope this helps if not sorry. :)
because the denominator is on the bottom, you have to find a number which both 12 and 9 can be divided by. In this case the only answer that isn't a decimal is 3
Eliminate y's
multiply second equaiton by 4
4x+4y=-4
add to first equation
3x-4y=-24
<u>4x+4y=-4 +</u>
7x+0y=-28
7x=-28
divide both sides by 7
x=-4
sub back
x+y=-1
-4+y=-1
add 4 to both sides
y=3
(x,y)
(-4,3)
D is answer
It would have to be 44°. If you go around 360° nothing happens. So subtract 404°-360° and you get 44°. 44°<90° from the x-axis so we are done.
