Answer:
1680
Step-by-step explanation:
Since there are 4 places (frames) to put up each poster, we think individually:
In the first place they can place ANY OF THE 8 POSTERS
In 2nd place, they can place ANY OF THE REMAINING 7 POSTERS
In 3rd place, they can place ANY OF THE REMAINING 6 posters
and
in last place, they can place ANY OF THE REMAINING 5 posters
The number of ways is the multiplication of them all, so:
8 * 7 * 6 * 5 ways = 1680 ways
The correct way to write this equation is .25x-3=12. The .25 is interchangeable with
So if Hugo has saved $10 the first week and $6 for the next 6 weeks the answer would be $46.
you can either add up 6 six times or you can multiple 6 by 6.
6+6+6+6+6+6=36 or 6×6=$36
then you add the $10 from the first week & the $36 from the $6 you saved for 6 weeks to get your final answer of $46.
$36+$10=$46
Solve your system of equations.
3x+2y=8;2x+3y=2
Solve 3x+2y=8 for x:
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8
3x/3=−2y+83(Divide both sides by 3)
x=−2/3y+8/3
Substitute (−2/3y+8/3) for x in 2x+3y=2:
2x+3y=2
2(−2/3y+8/3)+3y=2
5/3y+16/3=2(Simplify both sides of the equation)
5/3y+16/3+−16/3=2+−16/3(Add (-16)/3 to both sides)
5/3y=−10/3
5/3y5/3=−10/35/3(Divide both sides by 5/3)
y=−2
Substitute (−2) for y in x=−2/3y+8/3:
x=−23y+83
x=−23(−2)+83
x=4(Simplify both sides of the equation)
Answer is A)
