Answer:
Step-by-step explanation:
Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...
k + (k -5) = 21
2k = 26 . . . . . . . add 5, collect terms
k = 13 . . . . . . . . . divide by 2; Kim's age
k -5 = 8 . . . . . . . Jack's age
Kim is 13; Jack is 8.
Answer:
y = 5
Step-by-step explanation:
We khow that x and y are consecutive integers and that x^2 is greater than y^2 since x^2-y^2=11
● so x is greater than y
● wich means that x = y+1
● x^2-y^2=11
● (y+1)^2-y^2 = 11
● y^2+2y+1-y^2=11
● 2y + 1 = 11
● 2y +1-1 = 11-1
● 2y = 10
●2y/2 = 10/2
● y = 5
The answer I think should be 15 hope this helps
Answer:
values of q are q=0,-9,5/6
Option B is correct
Step-by-step explanation:
We need to solve the equation:
2q(q+9)^2(6q-5)=0
We will be using zero factor polynomial i,e if ab=0 then a=0 and b=0
so, 2q(q+9)^2(6q-5)=0
2q =0, (q+9)^2 =0 and (6q-5)=0
Finding values of q
2q = 0 => q=0
(q+9)^2 =0 => taking square root
q+9 = 0
q = -9
(6q-5)=0 => 6q-5=0
6q = 5
q = 5/6
So, values of q are q=0,-9,5/6
Option B is correct
