I Nisa buy dollars worth of stock and gained $25 per year Kevin bad for hundred dollars worth of stock in the last $35 per year
alisha [4.7K]

Answer: x= 5 years and y = $225

Step-by-step explanation:

Since we have given that

Amount Nisa gained per year = $25

Amount Kevin lost per year = $35

According to question,

y=100+25x\\\\and\\\\y=400-35x

so, it becomes,

100+25x=400-35x\\\\25x+35x=400-100\\\\60x=300\\\\x=\frac{300}{60}\\\\x=5

so, For x= 5 years,

Their income of Nisa and loss of Kevin will be

y=100+25x\\\\y=100+25\times 5\\\\y=100+125\\\\y=\$225

Jan 18 Spiral Review<br> Find the surface area of the following complex shapes.
zepelin [54]

Answer:

320 in.²

Step-by-step explanation:

Let's think of the shape as a normal rectangle with a height of 16 inches. Now all we need is the length. If you look at the right corner, it looks like a piece has been cut out. Since that piece has the same length and height of 8 inches, it is a square. This tells us the missing length of the entire length of the rectangle. Now the length of the rectangle is 16 inches + 8 inches, which is 24 inches.

The total area of the rectangle is 16 × 24, which is 384.

Then from the total area, we just need to subtract the area of the cut-out part. The area of the cut-out square is 8 × 8, which is 64.

384 - 64 = 320

The total surface area of the following complex shape is 320 in.²
