what operation should be done first to solve 5x+3=28?

Answer:

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

Finding the circumference of the circle in terms of pi

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

Finding the circumference of the circle using π = 3.14

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches

Answer:

69/8

Step-by-step explanation:

-55/8 + 31/2

The lowest common denominator (LCD) is 8.

(-55 + (8/2)31) / 8

(-55 + 124) / 8

69/8

Answer:

x > 2

Step-by-step explanation:

4x + 2 > 10

Subtract 2  from both sides;

4x > 8

Divide both sides by 4;

x > 2

Answer:

x > 2

Equality Property

Step-by-step explanation:

Step 1: Define

4x + 2 > 10

Step 2: Solve for x

Here we see that any value x greater than 2 would work as a solution to the inequality.

Answer:

C.

Step-by-step explanation:

if four people dont want it and there are 14 people total, then it would be (14-4). The photos cost $3 so it would be 3(14-4)=$30

Answer:

C

Step-by-step explanation:

from 14 friends you have to take away the 4 that do not want a photo

(14- 4 ) is the number of kids Charlie will have to pay for

and will pay $3 for each (14-4) kids

3(14-4)  is the cost

3(14-4) = 3*10 = is $30

Answer:10 presents fell off

Step-by-step explanation: to find 2/6 we can start with finding 1/6 because it’s easier. To do that we divide 30 by 6 which equals 5. because 5 is 1/6 5x2 is 2/6 so the answer is 10

Answer:

you put 30 over 1 than you then you 2 over 6 then subtract then

Step-by-step explanation:

so it would look like this

30/1 - 2/6=

Answer:

The commission earned on all sales over

$12 500 is $750

Step-by-step explanation:

$12 500 is over $8000 so the commission is 6%

Turn the percentage into a decimal

[tex]6 \div 100 = 0.06[/tex]

Multiply that decimal with the earned sales price

[tex]0.06 \times 12500[/tex]

= $750

Answer:

x = 8

Step-by-step explanation:

do distribution: 4x - 28 + 12 = 16

simplify: 4x - 16 = 16

add 16 to both sides: 4x = 32

divide both sides by 4: x = 8

Let me know if you need me to explain it more, good luck!

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × [tex]\frac{1}{4}[/tex] = 1

4 × [tex](-\frac{1}{2})[/tex] = -2

Here is the simplified expression:

[tex]12 + c - 2d[/tex]

=================================================

Work Shown:

[tex]x = 27.2 \text{ cm}\\\\x = 27.2 \text{ cm} * \frac{1 \text{ inch}}{2.54 \text{ cm}}\\\\x = \frac{27.2}{2.54} \text{ inch}\\\\x \approx 10.7086614 \text{ inches}\\\\x \approx 10.7 \text{ inches}\\\\[/tex]

Effectively all we do is divide 27.2 over 2.54 to convert from cm to inches.

This means that 27.2 cm is roughly the same as 10.7 inches.

I rounded to one decimal place because 27.2 is to one decimal place. If your teacher says for you to round otherwise, then follow those instructions of course.

Tom will have to sell at least 10 TVs to get the bonus and to get $1,500

Step-by-step explanation:

Total: The same or above 1500

Tom gets paid 100 for each TV = 100t

He can get a 500 bonus by selling a certain amount = 500

100t + 500 ≥ 1,500

100t + 500 - 500 ≥ 1500 - 500

100t ≥ 1000

100t ÷ 100 ÷ 1000 ÷ 100

t ≥ 10

Tom will have to sell at least 10 TVs to get the bonus and to get $1,500

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Step-by-step explanation:

Firstly, add 10,009 and 274,628 together which is equal to 284, 637

then you're going to multiply 284,637 and 38,986

which is equal to 11,096,858, 082

Answer:   The larger number is 40.

The smaller number is 19

Step-by-step explanation:

x + (x-21) = 59   This is the number and the  number difference add to 59.

x + x = 59 + 21    Add 21 to both sides. Combine like terms.

2x = 80  divide both sides by 2

x= 40 This is the first number.  Subtract 21 to get the second number

40 - 21 = 19

The difference between 40 and 19 is 21.

19 + 40 = 59

Given :

A sixth-grade student bought three cans of tennis balls for $4 each.

The sales tax for each can was $0.95.

To Find :

The total amount the student spent.

Solution :

Price of each can including taxes :

p = $( 4 + 0.95 )

p = $4.95

So, price of 3 such cans including tax is :

P = p×3

P = $( 4.95×3 )

P = $14.85

Therefore, total amount spend by the student is $14.85 .
