Please Answer This! Im Desperate UvU,

Answers

Answer 1
Part A:

x=5
4x-1 ≤19
4(5)-1 ≤19
20-1 ≤19
19 ≤19

x=5
4x-1<19
4(5)-1<19
19<19

Explanation:
In problem one the greater then symbol has a line under it, this means that the symbol now means greater then or equal to. Since 19 is equal to 19 it is correct. In problem to the greater then symbol has no line under it meaning it only means greater then. Since 19 is not greater then 19 it is false.
So basically the difference is:
≤ = greater then or equal to
< = greater then


Part B:
5x+2=47
-2 -2
5x=45
/5 /5
x=9

Explanation:
Since when you solve the equation x=9 the value 9 from the set makes the equation.


Hope this helped :)

what is 6 x 18 using the distributive property

Answers

Answer:

108 is the answer and there is no explanation for this. Youc can directly multiply it.

Answer:

648

Step-by-step explanation:

There is no distributive property necessary. You would use distributive property in a problem like a(b + c).

a(b + c)

ab + ac

That is distributive property. 6 × 108 doesn't require distributive property.

6 × 108 or 6(108) or 108(6) = 648
