Answer:

[tex]2(z+3)[/tex]

Step-by-step explanation:

We are given that  the expression

[tex]z+(z+6)[/tex]

We have to find the expression which is equivalent to given expression.

[tex]z+z+6[/tex]

To find the equivalent expression we will combine like terms

Now, combine like terms we get

[tex](z+z)+6[/tex]

[tex]2z+6[/tex]

By using the property

[tex]a+a+..+a(n times)=na[/tex]

Therefore, the expression we get

[tex]2z+6[/tex]

Now, taking common 2

[tex]2(z+3)[/tex]

Hence, the expression which is equivalent to given expression is given by

[tex]2(z+3)[/tex]

Given:

School A rented and filled 5 vans and 9 buses with 499 students.

School B rented and filled 10 vans and 9 buses with 539 students.

To find:

The number of student a bus can carry.

Solution:

Let x be the number of student a van can carry and y be the number of student a bus can carry.

School A rented and filled 5 vans and 9 buses with 499 students.

[tex]5x+9y=499[/tex]         ...(i)

School B rented and filled 10 vans and 9 buses with 539 students.

[tex]10x+9y=539[/tex]        ...(ii)

Subtract (i) from (ii).

[tex]10x+9y-5x-9y=539-499[/tex]

[tex]5x=40[/tex]

[tex]x=\dfrac{40}{5}[/tex]

[tex]x=8[/tex]

Putting x=8 in (i), we get

[tex]5(8)+9y=499[/tex]

[tex]40+9y=499[/tex]

[tex]9y=499-40[/tex]

[tex]9y=459[/tex]

Divide both sides by 9.

[tex]y=\dfrac{459}{9}[/tex]

[tex]y=51[/tex]

Therefore, a bus can carry 51 students.

Answer:

Total number of slices = 9 slices

Step-by-step explanation:

Given:

Diameter of a cake = 12 cm

Area of one slice = 4π cm²

Find:

Total number of slices

Computation:

Radius of cake = 12 / 2 = 6 cm

Area of circle = πr²

Area of circle = π(6)²

Area of circle = 36π cm²

Total number of slices = Area of circle / Area of one slice

Total number of slices = 36π / 4π

Total number of slices = 9 slices

Answer:

9 full slices

The time would be 1:10 pm.

Step-by-step explanation:

9:20 + 3 hours is 12:20.

50 minutes after 12:20 is 1:10.

Answer:

1:10

Step-by-step explanation:

Hey there

to solve this problem think 9:20 and 3:50 as ratios. In this problem we will add these too

9:20 + 3:50= 12:70

so, if it is 12:70. in one hour there is 60 and in the 12:70 it 70. so we add one more hour it will be 1:10

= 1:10

Answer:

7^2+8^2+56^2 = 57^2

Step-by-step explanation:

If you look at it, you can decipher a pattern. 3x4 = 12, and then add and you get the number on the right.

So, with this we can infer it will go 7x8 = 56^2, which will be equal to 57^2

Hope that helps!

The number of square feet that you need to add will be 24 square feet.

Let W be the rectangle's width and L its length.

The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be

Area of the rectangle = L×W square units

You're going to build 3 feet by 7 feet garden. If you want to surround it with a 1-foot wide brick border.

Then the area of the garden and border will be

A₁ = (3 + 2)(7 + 2)

A₁ = 5 x 9

A₁ = 45 square feet

The area of the garden will be

A₂ = 3 x 7

A₂ = 21 square feet

The number of square feet that you need to add will be

A = A₁ - A₂

A = 45 - 21

A = 24 square feet

The number of square feet that you need to add will be 24 square feet.

Answer:

Step-by-step explanation:

area is radius squared times pi(3.14) the radius is half of the diameter  they give you the diameter so divide it by 2 to get the radius then multipy that by pi(3.14)

The approximate area of the circle of the given diameter of 70 inches will equal 3848 in². Hence, option C is correct.

The area of an object is the amount of two-dimensional space it occupies. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given values in the question,

Diameter of circle = 70 inches

Then, the radius of the circle will be.

r = 70/2

r = 35 in²

Use the formula of the area of a circle,

[tex]A =\pi\ r^{2}[/tex]

A = 3.14 × 35²

A = 3848 in².

Answer:

The expression represents the difference is (72 - 5d) dollars

Step-by-step explanation:

Let us solve the question

∵ Kenichi took $72 to a concert

∴ The total money with him = 72 dollars

∵ He paid for 5 tickets that each cost d dollars

→ That means he bought 5 tickets each cost d dollars

∴ The cost of the tickets he paid = 5 × d

∴ The cost of the tickets he paid = 5d dollars

∵ The money left with him = total money he has - the amount he spent

∵ The total money = 72 dollars

∵ The amount he spent = 5d dollars

∴ The money left with him = 72 - 5d  

∴ The expression represents the difference is (72 - 5d) dollars.

Answer:

She would leave a tip of $1.28

Step-by-step explanation:

So first if we add all of the expenses together we get $8.50. So her who lunch was $8.50. If she wants to leave a 15% tip, it would be 15% of her total cost so, 15% of $8.50 is 1.275. Rounded that's $1.28. She would leave $1.28 tip.
