This is a question of randomness so there really is no answer. I would guess 7 since that is the center page and you're more likely to open it up in or near the middle
Answer:
a=
Step-by-step explanation:
You are looking for <em>a </em>meaning <em>a </em>needs to be alone.
So subtract -3b+9c from both sides
14a=18+3b+9c
Then divided the right side by 14 to get<em> a</em> alone.
a=
To solve the equation you can first subtract 4x from both sides. Then,
Since you arrive at something false, -5 is not equal to negative 8, so the equation has no solution.

Answer:
(b) Ingrid’s claim is correct, but her steps are incorrect
Step-by-step explanation:
As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.
Step 3 should read ...
0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1
Step 4 should read ...
0 + sin(y) = sin(y)
So, Ingrid's conclusion is correct, but her steps are incorrect.
Answer:
The required equation is
Charges = $(22 * No of Rooms cleaned)
Step-by-step explanation:
Direct Relation:
The relation ship in which if one quantity increase then it results in the increase of the other quantity too and if it decreases then other quantity will decrease too.
it is represented by
a∝b
a= kb
where k is constant of proportionality
Now for the given question
Charges is directly proportional to no of rooms cleaned
It is
Charges ∝ No of rooms cleaned
It could be written as
Charges = K * No of rooms cleaned
Here k is given as $22 for each room
so
it becomes
Charges = $(22 * No of Rooms cleaned)
which is the relationship in form of equation!!!
