Answer:
q1: yes
q2: no
Step-by-step explanation:
2(5)+10(1)=20
10+10=20
20=20
(5)+(1)=6
5+1=6
6=6
(8)=(1)+3
8=1+3
8=4
Answer:
Step-by-step explanation:
x has to be equal to or less than a -5 to get (4 + x) to be a negative number.
x has to be equal to or greater than -10 for (11 + x) to be a positive number.
Therefore, any number between -10 and -5 will work.
The rule is minus 5.
So 20, 15, 10, 5, 0, -5
answer:X=k/n-3
explain:move all terms to the left side and set equal to zero. then set each factor equ to zero!
I hope this helps
the number is 6
let the number be n , then the difference of this number and 3 is n - 3
4 times this is 4(n - 3) = 12 ( solve for n )
divide both sides by 4
n - 3 = 3 ( add 3 to both sides )
n = 3 + 3 = 6
the number is 6
