The answer is 7x + 3

First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.

Then, you add x+2 + x+1
Combine like terms and you have 2x+3

Add 5x + 2x+3 and you have 7x +3

I’m bad at explaining, so here are the steps.

Which expression is equivalent to \root(3)(x^(5)y)
san4es73 [151]

Answer:

\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}

Step-by-step explanation:

Given

\sqrt[3]{x^{5}y}

Required

The equivalent expression

We have:

\sqrt[3]{x^{5}y}

Rewrite as an exponent

\sqrt[3]{x^{5}y} = (x^{5}y)^\frac{1}{3}

Open bracket

\sqrt[3]{x^{5}y} = x^{5*\frac{1}{3}}y^\frac{1}{3}

\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}

You run a hotel with 1465 rooms. You currently have 296 rooms reserved by individuals and 651 rooms reserved by groups for a par
Tanya [424]

Answer:

Hotel is over booked by 140 rooms

Step-by-step explanation:

Total number of hotel rooms = 1465

number reserved by individuals = 296

number reserved by groups = 651

booking rates = 67% for individual ,  56% for groups

<u>Determine if you are under booked or overbooked for the weekend </u>

let X represent the number of rooms booked by individuals

and Y represent the number of rooms booked by groups

number of reserved room for individuals

= 67% of X = 296

X = 67% + 33%

   = 296 + ( (296 / 67 ) * 33 )

   = 296 + 146 ≈ 442

number of rooms reserved for groups

= 56% of Y = 651

Y =( 651 / 56 ) * 100

   ≈ 1163

Total rooms booked = X + Y

                                  = 442 + 1163 = 1605

<u>To determine if under booked or over booked </u>

Total rooms booked - Total number of hotel rooms

 =  1605 - 1465

 =  140 ( Your Hotel is over booked )

I need help on the following questions.
Zigmanuir [339]
For the first one, you just need to divide the amount of feet by 3 to get the amount of yards (there are three feet in a yard). 

1431 / 3 = 476 2/3
 
The 102nd floor of the Sears Tower is 476 2/3 yards from the ground.

Second, you just need to multiply the amount of centimeters by 10 (there are 10 millimeters in a centimeter).

16 * 10 = 160

The butterfly has a wingspan of 160mm.

Third, the measurements are indeed 
7. =
8. =
9. <
10. >
11. > 
12. =

Fourth, you just need to know your conversion factors.
1. There are 3 feet in a yard. 42 / 3 = 14 yards
2. There are 1000 meters in a kilometer. 2350 / 1000 = 2.35 km
3. 12 inches in a foot. 18 * 12 = 216 inches
4. 10 decimeters in a meter. 289 * 10 = 2890 dm
5. 1760 yards in a mile. 1760 * 5 = 8800 yds
6. 10 millimeters in a centimeter. 35 * 10 = 350 mm

Hope that was helpful =)
