Answer:
nj+k = p
Step-by-step explanation:
n = (p-k)/j
Multiply each side by j
nj = (p-k)/j *j
nj = p-k
Add k to each side
nj +k = p-k+k
nj+k = p
4.876 < 4.879
the first three digits are the same, however the last digit, which is the fourth digit from both sides are 6 and 9
6 is less than 9 therefore that determines the whole value of 4.876 to be less than 4.879
<span>b – 2a – c
= 9 - 2(-3) - (-6)
= 9 + 6 + 6
= 21

21</span>
Let us assume the number of hours volunteered by Katie = x
Number of hours volunteered by Elizabeth = y
Number of hours volunteered by Siobhan = z
After one week,
x = y + 3
z = y - 1
After 3 weeks
3x = 3 (y + z)
Dividing both sides by 3, we get
x = y + z
Putting the value of x from the first equation in the third equation, we get
x = y + z
y + 3 = y + z
z = 3
Now putting the value of z in the second equation, we get
z = y - 1
3 = y - 1
y = 4
Putting the value of y in the first equation, we get
x = y + 3
= 4 + 3
= 7
The number of hours volunteered by Katie = 7 hours
Number of hours volunteered by Elizabeth = 4 hours
Number of hours volunteered by Siobhan = 3 hours
I would say -13 because y = - 10 - 3 would mean that what ever -10 minus 3 equals is what y equals and -10 - 3 is -13
