<span>5/13 + 7/13 = 12/13 < 1
5/12 + 7/12 = 12/12 = 1
5/11 + 7/11 = 12/11 > 1
Hope this helps.</span>
Step-by-step explanation:
abx² - (a⁴ + b⁴)x + (a³b³) = 0
(ax - b³)(bx - a³) = 0
Therefore x = b³/a or x = a³/b.
X=5 is your answer to this
Answer:
x=10, y=5
Step-by-step explanation:
For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.
x-2y=0
x=2y
You can substitute 2y as x on the first equation (x+4y=30).
2y+4y=30
6y=30
y=5
Plug y=5 into any equation.
x+4(5)=30
x+20=30
x=10
Answer/Step-by-step explanation:
a. m<h = x°
Two angles to use in finding x are <h and 55°
Angle pair formed: linear pair angles
b. x° + 55° = 180° (linear pair)
Subtract 55° from each side
x + 55 - 55 = 180 - 55
x = 125°
c. Given: m<n = y°
Two angles to use in solving for y are: <h and <n
Angle pair formed: alternate exterior angles
d. m<n = y° (given)
m<n = x° = 125° (as solved in 2b)
Therefore:
y = x (alternate exterior angles are congruent)
thus:
y = 125° (substitution)
