Easy,

23y-(7x-2y)+x

<span>There is an imaginary</span> 1 in front of the parentheses, making it,

23y-1(7x-2y)+x

Now, distribute the 1.

-1*7x= -7x
and
-1*-2y= 2y

Leaving your problem looking like...

23y-7x+2y+x

Combine your apples and oranges.....

25y-6x

Thus, your answer.

Kitty [74]

Answer:

Part 1) The new distance from the water to the top of the tank is $1.979\ in$

Part 2) The maximum number of balls that can be put into the tank with the tank not overflowing is 95

Step-by-step explanation:

step 1

Find the total volume of the tank

$V=20*10*15=3,000\ in^{3}$

step 2

Find the volume of the tank if the water level is two inches below the top of the tank

$V=20*10*(15-2)=2,600\ in^{3}$

step 3

Find the volume of the glass sphere

The volume of the glass sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=1\ in$

assume

$\pi=3.14$

substitute

$V=\frac{4}{3}(3.14)(1)^{3}$

$V=4.2\ in^{3}$

step 4

What is the new distance from the water to the top of the tank?

we know that

$2 in -----> represent (3,000-2,600)=400\ in^{3}$

using proportion

Find how many inches correspond a volume of $4.2\ in^{3}$

$\frac{2}{400}\frac{in}{in^{3}}=\frac{x}{4.2}\frac{in}{in^{3}}\\ \\x=4.2*2/400\\ \\x=0.021\ in$

The new distance from the water to the top of the tank is

$2-0.021=1.979\ in$

step 5

Find how many of these balls can be put into the tank with the tank not overflowing

we know that

The volume of one ball is equal to $4.2\ in^{3}$

using proportion

$\frac{1}{4.2}=\frac{x}{400}\\ \\x=400/4.2\\ \\x=95.23\ balls$

therefore

The maximum number of balls that can be put into the tank with the tank not overflowing is 95

Answer:

The answer is "The second choice".

Step-by-step explanation:

$r=6\\\\h=13 \\\\$

Formula:

$A=2\pi rh$

$=2\times 3.14 \times 6 \times 13\\\\=2\times 3.14 \times 78\\\\=3.14 \times 156\\\\=3.14 \times 156\\\\=489.84 \approx 489.8 ft^2$

Step2247 [10]

Answer:

4 T-shirts and 5 long sleeves shirts.

Step-by-step explanation:

T-shirt cost =$10

Long sleeve shirt cost = $15

Total number of shirts = 9

Total number of T-shirts = 4

Cost of 4 T-shirts = 4 × 10 =$ 40

Total number of long sleeve shirt = 5

Cost of 5 long sleeve shirt = 5 × 15 =$ 75

Verification:

75+40 = $115 proved!
