Five times the sum of x and negative two, or five times the difference of x and two
Answer:
7 9/10
Step-by-step explanation:
First, we need to add 4 2/3 and 5 2/5.
We should begin with converting the fractions into improper fractions.
4 2/3 + 5 2/5= 14/3 + 27/5
Now, we find the common denominator
= 70/15 + 71/15
We can add:
= 141/15
And simplify.
= 9 2/5
Finally, we subtract 1 1/2 from 9 2/5
Your answer is 7 9/10. Hope this helps!

the Highest common factor of 130,260,390 = 130
130 = 2⋅5⋅13
260 = 2⋅2⋅5⋅13
390 = 2⋅3⋅5⋅13
Common multipliers (130; 260; 390): 2, 5, 13
Now to find the highest Common factor you need to multiply the common factors
Answer: (130 ; 260 ; 390) = 2 ∙ 5 ∙ 13 = 130
