One number is 5 more than twice another and their sum is 23.
what system of equation represents the word problem?

Let denote the numbers with X and Y. From the statement that one number is 5 more than twice another we can write the following: X=2*Y+5

From the fact that their sum is 23 we can write: X+Y=23, so it follows: X=23-Y

The following system of equation represents the problem:

X=23-Y   and X=2*Y+5

The solution of the problem is:

23-Y=2*Y+5

23=3*Y+5

23-5=3*y

18=3*Y

Y=18/3=6

X=23-Y=23-6=17

Step-by-step explanation:

Mrs Jackson bakes on xth day of December until 24th December.

Absolute value of the function f(x) = |x - 24| represents the number of cookies baked.

For x = 0

f(0) = |0 - 24| = 24

For x = 4

f(4) = |4 - 24| = 20

For x = 8

f(8) = |8 - 24| = 16

For x = 12

f(12) = |12 - 24| = 12

For x = 16

f(16) = |16 - 24| = 8

For x = 20

f(20) = |20 - 24| = 4

For x = 24

f(24) = |24 - 24| = 0

For x = 28

f(28) = |28 - 24| = 4

For x = 31

f(31) = |31 - 24| = 7
