X=5/8 or x=-4/3
here is the work if needed...
24x^2+17x-20=0
Step one: Factor left side of equation.
(8x-5)(3x-4)=0
Step two: Set factor equal to 0.
8x-5=0 or 3x-4=0
x=5/8 or x=-4/3
X = 4 because 1 over 24 times 4 is 4 over 24 which is converted to 1 over 6
<span>−y−3(−3y+5)
= </span><span>−y + 9y - 15
= 8y - 15
answer
</span><span>d.8y-15</span>
If one is 50 cents, then to get to one dollar we need 2 of those. also, one dollar equals 100 cents, and 50+50=100, so then the answer would be that you need to have 2 coins of the half-dollar to get to 1 dollar. i hope that this helps you, have a great day! =)
