Answer:
A. (y+z=6) -8
Step-by-step explanation:
You will use the process of adding together the like terms. Since in equation Q, we have 8y, we need -8y in equation P. Answer A is the only one that will give us -8. You have to distribute -8 across all the variables and numbers in the parenthesis.
Answer:
-5.9n+9.1
Step-by-step explanation:
3.1 - 3.9n - 2n + 6=
Combind like terms
Step 1: -3.9 - 2n=-5.9n
Step 2: 6 + 3.1=9.1
Combine:
-5.9n+9.1
The other sides are 12cm and 5cm. This is a Pythagorean triple. It is useful to know them!!!

The value of y for the system of equation is -1/2 .
<h3>What is a System of Equation ?</h3>
A system of equation is a set of equation that have common solution
The set of equation given is
3x+4y=4
2x−4y=6
To solve the system , Elimination method will be used
Add equation 1 and 2 to eliminate y
5x = 10
x = 2
Substitute the value of x in equation 1 to determine y
3x +4y = 4
6 + 4y = 4
4y = -2
y = -1/2
Therefore the value of y for the system of equation is -1/2 .

Answer:B
V = l. w. h
Step-by-step explanation:
Volume of a rectangular prism is base area * height
The base is a rectangle, hence, the base area equals area of a rectangle which is length * width
Replacing base area (B) in the formula,
V = Bh
V= l * w * h
