Answer:
Step-by-step explanation:
-9/2
1) g=6x
<h3> <u>x = g/6</u></h3>
2) u=2x-2
<h3> <u>x = ( u+2) / 2</u></h3>
3) z=m-x
<h3> <u>x = m - z</u></h3>
4) g=ca
<h3> <u>a = g/c</u></h3>
5) u=x-k
<h3> <u> x = u+k</u></h3>
6) g=c+x
<h3> <u> x = g - c</u></h3>
7) u=k/a
<h3> <u>a = k/u</u></h3>
8) g=xc
<h3> <u>x = g/c</u></h3>
9) 12am=4
<h3> a = 4/ 12m</h3><h3> <u> a = 1/3m</u></h3>
10) -3x+2c=-3
<h3> x = (-3 - 2c) / - 3</h3><h3> <u> x = ( 3 - 2c) / 3</u></h3>
.... Hope this will help....
Answer:
n=-9
Step-by-step explanation:
subtract 19 to both sides
19-19=0
10-19=(-9)
n=-9
to verify add 19+(-9)=10
hope this helps :3

Answer:
The answer is c. 16x2 + 24xy + 9y2.
Step-by-step explanation:
Let the number of pieces of gum be g and the cost of each piece be c.
gc=2.16. Also, (g+3)(c-0.01)=2.16.
So gc=(g+3)(c-0.01)=gc-0.01g+3c-0.03.
And -0.01g+3c=0.03 and c=2.16/g. -0.01g+6.48/g=0.03.
-0.01g²+6.48=0.03g; 0.01g²+0.03g-6.48=0 which can be more conveniently written:
g²+3g-648=0=(g+27)(g-24) so g=24, the number of pieces she actually had.
CHECK The cost of the gum, c=2.16/24=9 cents.
A penny cheaper makes the gum 8 cents a piece and she could have bought 27 pieces instead of 24.
