Answer:
Q=2
Step-by-step explanation:
hello :
the solution to the system is
{(x,y) : x-3y=4} means infinty solution
X-3y=4
....(*)
Qx-6y=8....(**)
multiply (*) by -2
-2x+6y = -8 (***)
add (*) and (***) : (Q-2)x =0
this ie true for reals x when Q=2
Answer: 12.37ft
<h2 />
Step-by-step explanation:
The formula to find the missing side of a triangle is a^2 + b^2 = c^2
so all you have to do is put 3 and 12
3^2 + 12^2 = c^2
9 + 144 = c^2
153 = c^2
√153 = 12.37
Answer:

*
= 1.4142</h3><h3>
= π =3.14159</h3><h3>
= π² = 9.8696</h3>
Explanation:
1.) Rewrite √24 = 
Rewrite √54 =
Divide both terms by the denominator; √6 cancels. 2-3 = -1
2.) Rewrite as 
×
The 3's cancel. 10/2 = 5√2 in the numerator.
√5 × √5 = 5 in the denominator. The 5's cancel.
That leaves √2 ≈1.4142
3.) Divide the terms in the numerator by the term in the denominator.
√2's cancel. 10π/2 = 5π 8π/2 = 4π
Subtract and we are left with π = 3.14159
4.) The square roots are reciprocals. They multiply to 1
We are left with π × π = π² ≈ 9.8696

Answer:
x=9
Step-by-step explanation:
.5x+.7 = .3x+2.5
-.7 -.3x
.2x=1.8
/.2 /.2
x=9
.5(9)+.7=5.2
.3(9)+2.5=5.2
