Answer:
45
Step-by-step explanation:
let the longer tape be x
shorter tape be y
given
x+y=135⇒equation 1
also given
2y=x⇒equation 2
subtituting eq2 in eq1
2y+y=135
3y=135
y=135/3=45
hope this helps
The second value: 5.099 is the lesser known value
Answer:
Im not sure but im pretty sure it is 9+144
Step-by-step explanation:
X = 4 + (x^2 - 4) / (x - 8)
x(x - 8) = 4(x - 8) + x^2 - 4
x^2 - 8x = 4x - 32 + x^2 - 4
-8x - 4x = -32 - 4
-12x = -36
x = -36/-12
x = 3
Answer:
x=-9
y=4
Step-by-step explanation:
x + 3y = 3
x - 5y = -29
Multiply the second equation by -1
-x + 5y = 29
Add the two equations together to eliminate x
x + 3y = 3
-x + 5y = 29
---------------------
0x +8y = 32
Divide each side by 8
8y/8 = 32/8
y = 4
Now solve for x
x+3y =3
x+3(4) = 3
x+12 = 3
Subtract 12 from each side
x+12-12 = 3-12
x = -9
