Answer:

4x-43

Step-by-step explanation:

Here we have to simplify the expression 7(x – 4) – 3(x + 5)

In order to do so we first open the two brackets using distributive laws.

7(x – 4) – 3(x + 5)= 7*x-7*4-3*x-3*5

= 7x-28-3x-15

Now we bring the terms containing the x together and the terms not containing x together

= 7x-3x-28-15

we simplify them

= 4x-43

Hence

7(x – 4) – 3(x + 5)=4x-43 is the simplified expression

7(x - 4) - 3(x + 5)
Distribute the 7 and 3
7x - 28 - 3x - 15
4x - 43

List the single-digit divisors of 2100. I really need help

liberstina [14]

Answer:

1, 2, 3, 4, 5, 6, 7

Step-by-step explanation:

Prime factors of 2100 are:

2100 = 2*2*3*5*5*7

The single-digit divisors are:

1, 2, 3, 2*2= 4, 5, 2*3= 6, 7

-----------------------------------------------------------------

Another solution is you divide 2100 by all numbers 1 through 9 and list those divisible:

2100/1 = 2100, yes
2100/2 = 1050, yes
2100/3 = 700, yes
2100/4 = 525, yes
2100/5 = 420, yes
2100/6 = 350, yes
2100/7 = 300, yes
2100/8 = 262.5, no
2100/9 = 233.33, no

So all the numbers from 1 to 7
