W is the variable.So try figuring out what the variable (W) represent and the value
From the system of equations, we have 3 unknowns and 3 equations. Therefore, it can be solved.
<span>3x - 2y + 2z = 30 (1)
</span><span>-x + 3y - 4z = -33 (2)
</span><span>2x - 4y + 3z = 42 (3)
We can write equation 2 x as a function of y and z and substitute the new equation to the other equations.
</span>x =3y - 4z + 33 (2)
3 (3y - 4z + 3)<span> - 2y + 2z = 30 (1)
</span>2 (3y - 4z + <span>3)</span> - 4y + 3z = 42 (3)
We simplify and solve the equations and we get values,
x = 4
y = -7
z = 2
Answer:
not solvable
Step-by-step explanation:
so there is a ratio of 5:3
that equals 8 parts
if you divide 60 by 8 that's 7.5
times 7.5 by 5 and you get 37.5
don't know how u get half a person but that's just how it is
The answer is: y=-4x+29
To solve this, you need to know the y-intercept.
1. y=-4x+b
2. 9+-4(5)+b
3. 9=-20+b
4. b=9+20
5. b=29
6. Substitute into y=-4x+b
Answer:
74
Step-by-step explanation:
(80+96+81+89+64)÷5 = 84
Used the formula to get the average of a number. Hope this helps
