On subtracting 6 from three times of a number, we get 15. Then the number is

Answers

Answer 1

Answer:

Step-by-step explanation:

If we take the number as 7 so 3 times 7 is

3 x 7 = 21

Subtracted by 6 = 21 - 6= 15

So the number is 7

Answer 2

Answer:

Step-by-step explanation

Add the subtracted value to the other given value

15+6=21

Since we know it is 3 times the number, divide by 3 to get the number

21/3=7

Check:

21=3x7

21=21

Solve inequality 5-3(4x-5)<32

Answers

Answer: x > -1

Step-by-step explanation:

1) Subtract 5 from both sides

-3(4x - 5) < 27

2) Divide both sides by -3 (Remember to change the inequality sign to face the other way, because you have multiplied/divided by a negative number)

4x - 5 > -9

3) Add 5 to both sides

4x > -4

4) Divide by 4 on both sides

x > -1

Find the coterminal angle between 0 and 360°of the angle -280°

Answers

Answer: So, the coterminal angle of 450° is -90°.

Step-by-step explanation:(i) 395°

Write 395° in terms of 360°.

395° = 360° + 35°

So, the coterminal angle of 395° is 35◦

(ii) 525°

Write 525° in terms of 360°.

525° = 360° + 165°

So, the coterminal angle of 525° is 165°.

(iii) 1150°

Write 1150° in terms of 360°.

1150° = 3(360°) + 70°

So, the coterminal angle of 1150° is 70°.

(iv) -270°

Write -270° in terms of 360°.

-270° = -360° + 90°

So, the coterminal angle of 270° is 90°.

(v) -450°

Write -450° in terms of 360°.

-450° = -360° - 90°

So, the coterminal angle of 450° is -90°.

5(3x-2)=4(2x+1)
(15x-10)=(8x+4)
7x-10=4
7x=14
X=2
Explanation:
I multiplied everything inside the parenthesis by the number on the outside, making the equation 15x-10=8x+4, then I combined like terms, so I subtracted 8x on both sides and added 10 to each side, making the equation 7x=14, this means that 14/7 and 7/7 is the last step, which leaves you with the answer of x=2

Stephen, Gavin and Jim share some sweets in the ratio 3:1:2. Stephen gets 24 sweets. How many sweets are there altogether?

Answers

Answer:

Step-by-step explanation:

Stephen : Gavin : Jim

3 : 1 : 2

We can say that this means the total amount of sweets get split between the 3 of them into 6 equal parts ( 3 + 1 + 2).

If Stephen gets 24 sweets, this means

3 parts = 24

So to find 1 part, divide 24 by 3.

1 part = 8 sweets

Now we can find the total by multiplying this by 6.

6 parts = 8 x 6 = 48 sweets.

The Israeli/Palestinian conflict is ALL about religion?TrueFalse The ultimate goal of operations management is to provide high-quality goods and services instantaneously in response to customer demand. Over the years, low cost often came at the expense of quality and flexibility. Furthermore, suppliers didn't always deliver when they said they would, so manufacturers had to carry large inventories of raw materials and components to keep producing. Such inefficiencies made U.S. companies vulnerable to foreign competitors who were using more advanced production techniques As a result of new global competition, companies have had to make a wide variety of high-quality custom-designed products at a very low cost. Something had to change on the production floor to make that possible. Several major developments have made U.S.companies more competitive: (1) computer-aided design and manufacturing (2) flexible manufacturing, (3) lean manufacturing, and (4) mass customization, (5) CAD(6) CAMMatch the company or role with the most appropriate manufacturing technique. Dress designer: In addition to helping in the design of products, the use of this system allows designers to work in three dimensions Shoe designer: The manufacturer programs the computer to make a simple design change, and then that change is readily Incorporated into production Purse designer: Software programs unite these two computer-aided support systems. While the software is expensive, it cuts as much as 80 percent of the time needed to program machines to make parts. Motor starters: Orders come in daily and, within 24 hours, the company's machines and robots manufacture, test, and package the starters-which are untouched by human hands. This system is so efficient it can even accommodate a special order (even a single item) in the assembly without slowing down the process.
