Answer:
see the procedure
Step-by-step explanation:
we know that


so
The value of digit 8 in 1.8 is 0.8
The value of digit 8 in 486 is 80
Divide the numbers
80/0.8=100
therefore
The value of the digit 8 in 486 is 100 times greater than the value of digit 8 in 1.8
or
The value of the digit 8 in 1.8 is 100 times less than the value of digit 8 in 486
1. False (F): Example: 2-3=-1∉N
2. True (T)
3. True (T)
4. False (F): Example: 3/4=0.75 which is not an integer
5. False(F) : Ratio can be negative if one but not the other integer is negative. Example: 5 : (-1)= -5
6. True (T)
7. True (T)
7-4=3
10-7=3
13-10=3
we can see that this is an arithmetic sequence with a difference of 3
the nth term=the first term +(n-1) times the difference
so a(n)=4+3(n-1)
Answer:
x=-7
Step-by-step explanation:
so if you multiply two negative numbers you get a positive and and -7 * -3 is just doing 3*7 which is 21 and that is the answer to -3*-7 and 21 minus 5 is 16 so there´s that and hope this helps
Answer:

Step-by-step explanation:
Notice that all three sides of the given triangle has one tick mark.
This means that all three sides are congruent, meaning that we have an equilateral triangle.
And for equilateral triangles, all three angles are also congruent.
So:

Also, recall that the interior angles of a triangle is always 180. Thus:

Substitute:

Combine like terms:

Substitute:

Multiply:

Thus:

And we are done!
