Answers

Answer 1
Answer:

Answer:

13 bracelets

If you have 260 cm of string and you need 20 cm for each bracelet, you have to divide 260 by 20. Which gives you 13
Answer 2
Answer:

Answer: Dorothea can make 13 bracelets.

Step-by-step explanation: If Dorothea has 260cm of strings, she should cut the string accordingly to set aside the strings. Cutting 260cm of 20cm length each would be the same as doing 260 divided by 20. If you do the math (mentally or using a calculator), you would get 13 pieces of strings, meaning Dorothea can make 13 bracelets. Hope this helped!

Solve. 3(4x + 2x) = 8

Answers

If you would like to solve the equation 3 * (4 * x + 2 * x) = 8, you can do this using the following steps:

3 * (4 * x + 2 * x) = 8
3 * 6 * x = 8
18 * x = 8    /18
x = 8/18
x = 4/9

The correct result would be 4/9.
The answer is B. 4/3

Answer:

Step-by-step explanation:

1) We would determine the cube root of 27 and find its square.

Cube root of 27 = 3

3² = 9

Solution = 9

2) 36³ = 46656

√36³ = √46656 = 216

3) we would find the 5th roof of - 243 and find its cube

5th root of - 243 = - 3

- 3³ = - 27

Solution = - 27

4) Looking at the expression, 40⅔, we can see that

a = 2

b = 3

c = 40

Answer: 1) We would determine the cube root of 27 and find its square.Cube root of 27 = 33² = 9Solution = 92) 36³ = 46656√36³ = √46656 = 2163) we would find the 5th roof of - 243 and find its cube5th root of - 243 = - 3- 3³ = - 27Solution = - 274) Looking at the expression, 40⅔, we can see that a = 2b = 3c = 40
