N+3=7. To find n, you need to have it by itself, so you can do that by subtracting 3 on both sides, so it would look like: n+3-3=7-3. Then you have n=4.
Answer:
$12000
Step-by-step explanation:
P=CRT
C=cost
R=rate
T=time
P=3000 x 8 x 50/100= $12000
Ok first you need to get a common denominator of 3 and 5 the smallest one would be 15 so then you rewrite both but remember if you do something to the bottom u have to do it to the top so you multiplied 3by 5 to get 15 to get your bottom then you have to times 5by 1 to get 5. So 5/15,same process for 3/5
5/15+ 9/15=9+5=14 so 14/15 (you keep the bottom the same) also it doesn’t need to be simplified because nothing can go into 14and 15 evenly
Same process for subtracting just subtract in the end so...
30/35-14/35= 16/35 also can’t be simplified evenly
In the end your answers are
1.14/15
2.16/35
Answer:
24 feet
Step-by-step explanation:
Let w represent the width of the rectangle. Then its length is 2w, and its area is ...
A = Lw
32 = (2w)(w) = 2w^2 . . . fill in the given values
16 = w^2 . . . . . . . . . . . . divide by 2
4 = w . . . . . . . . . . . . . . take the square root
8 = 2w = L . . . . . . . . . find the length
The dimensions of the yard are 8 feet long and 4 feet wide.
__
The perimeter is ...
P = 2(L +w) = 2(8 +4) = 2(12) = 24 . . . . feet
The perimeter of the rectangular back yard is 24 feet.
She bought 9 tickets (110.25 divided by 12.25) there is no rounding needed.
