Write the expression <br> 6 less 7 times a number
ANTONII [103]

Answer: 7x - 6

Step-by-step explanation:

Una librería consta de 5400 libros repartidos en 3 estanterías
pishuonlain [190]

Answer:

B = 900 Libros

A = 2700 Libros

C = 1800 Libros

Step-by-step explanation:

A = 3B

2B = C

A + B + C = 5400

3B + B + 2B = 5400

6B = 5400

B = 5400 / 6

B = 900 Libros

A = 3B

A = 3(900)

A = 2700 Libros

C = 2B

C = 2(900)

C = 1800 Libros

Dani says she is thinking of a secret number. As a clue, she says the number is the least whole number that has three different
pychu [463]

Answer:

30 = 2 x 3 x 5

Step-by-step explanation:

The secret number is the least whole number that has three different prime factors. Since, this is the least whole number it should have the 3 smallest prime numbers as its factors.

The 3 smallest prime numbers are: 2, 3 and 5

The number that will have 2, 3 and 5 as its only factors will be the least whole number with 3 different prime factors.

So, the secret number  must be = 2 x 3 x 5 = 30

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Mariana [72]
This is the question:

A bicycle manufacturing company makes a particular type of bike.

Each child bike requires 4 hours to build and 4 hours to test.

Each adult bike requires 6 hours to build and 4 hours to test.

With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week.

If c represents child bikes and a represents adult bikes,

determine which system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week

 

Now you can state the system of inequalities from the statements

1) First inequality based on the hours availble to buiding


Each child bike requires 4 hours, e<span>ach adult bike requires 6 hours to build and </span>the company is able to have up to 120 hours of building =>


4c + 6a ≤ 120


2) Second inequality based of the hours available to testing.


Each child bike requires 4 hours to test, each adult bike 4 hours to test and the company is able to have up 100 hours of testing time for a week =>


4c + 4a ≤ 100

Then the two inequalities are:

4c + 6a ≤ 120
4c + 4a ≤ 100

<span>The answer is Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Which you can verify by replacing in both equations 10 for c and 12 for a. Look:

1) 4(10) + 6(12) = 40 + 72 = 112 ≤ 120

2) 4(10) + 4(12) = 40 + 48 = 88 ≤ 100
