x - y + 5z = 3 .... (1)
4x + z = 0
.......(2)
x + 3y + z = -9 .......(3)
From (2) z = -4x, Substitute for z in (1) and (3):-
x - y + 5(-4x) = 3
-19x + y = 3 ......(4)
x + 3y - 4x = -9
-3x + 3y = -9
- x + y = -3 .....(5)
Subtract:- (4) - (5) we get
-18x = 0
x = 0
So z = -4x = 0
Substituting for x and z in equation (3):-
3y = -9
y = -3
Answer is x = 0 , y = -3 and z = 0
Answer: Mr. Carlo make the box with the height 4 feet or 5 feet .
Step-by-step explanation:
Since we have given that
Length of a storage box =5 feet
Breadth of a storage box =2 feet
Height of a storage box =h
Volume must be at least 36 cubic feet but no more than 56 cubic feet.
Possibility of h will be 4 and 5
<u>Case I:</u>
<u>Case II :</u>
So, it can be 40 cubic feet or 50 cubic feet .
So, height can be 4 feet or 5 feet .

Answer:
10x + 18
Step-by-step explanation:
First, we need to add like terms. Like terms are terms that are alike. For instance 8x and 2x are like terms. 15 and 3 are also like terms.
So, we have to add 8x plus 2x and 15 plus 3. That’s comes out to 10x plus 18.
Therefore, this expression is equivalent to 10x + 18.
Step-by-step explanation:
just subtract it
answer is 122.709
