225/400 = 9/16
56 1/4% simplest form is 9/16
The numbers that go into 120 are 10,12 and 6,20 and 3,40,. That's all I can think of at the moment.
B I'm pretty sure since p is the unknown number.
Answer:
<h2>15</h2>
Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 <em>add 15 to both sides</em>
4x = x + 45 <em>subract x from both sides</em>
3x = 45 <em>divide both sides by 3</em>
x = 15
