Step-by-step explanation:
A real number MUST be able to be represented on a number line.
All numbers can be placed on a number line including irrational numbers.
Numbers like π can be placed between 3.13 and 3.15. It is a number.
Numbers like x or ∑ isn't a "REAL" number because it has no value.
Answer:
you need to first figure out the equation f.
it says that 18=2/5f, so why don't we use inverse operation and multiply 18 by 5/2. and the answer would be....
Step-by-step explanation:
The propriety is zero propriety. Because 0 times a number is 0
Answer:
1 3/4
Step-by-step explanation:
You can set it up like the distrubtive property first
3/4(2+ 1/3) Next you use the distirbutive property instead of adding inside the parenthesis and you multiply the 3/4 by 2 and then the 3/4 by 1/3
Use 2 as 2/1 in fraction problems
3/4 * 2/1 Now multiply the numerators together and the denomenators together
3 * 2 = 6 4 * 1 =4
6/4
3/4 *1/3
3 * 1 =3
4 * 3 =12
3/12
Now we have to make them both like terms (same denominator) so we can add them, we will multiply the 6/4 by 3 (Both top and bottom)
6 * 3 = 18 4 *3 =12
18/12
Now we add the fractions
3/12 +18/12 = 21/12
Reduce that and you get
21/12 = 1 9/12 or 1 3/4
Answer:
B and C
Step-by-step explanation:
(-7)•8z = -56z
(-4)•(-7)=28
and
40•(-1.4)= -56z
40•0.7= 28
