Answer:
Step-by-step explanation:
Let the amount charged is y and number of hours is x.
Then the equations are as below.
<u>Attorney A:</u>
<u>Attorney B:</u>
<u>If the amounts are equal, then:</u>
- 150x + 250 = 175x + 150
- 175x - 150x = 250 - 150
- 25x = 100
- x = 4 hours
The Undefined term that is used to define an angle is a point.
<h2>Further Explanation: </h2><h3>Angle</h3>
- An angle is defined as the union of two rays with a common endpoint.
- The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.
<h3>A ray </h3>
It is a part of a line with one end point and proceeds on in one direction.
<h3>Naming of angles</h3>
- Angles can be named in three different ways;
- Using three Capital letters such as ∠ PQR, or ∠BCD. The middle letter represents the vertex of the angle. Therefore, the angles above are read as "angle PQR" and angle BCD.
- Using the Vertex of the angle. For example, in the case of ∠PQR, can also be called angle Q, while ∠BCD can be called angle C.
- Angles can also be named by placing any number or symbol at the vertex in the interior of the angle. Such that angles can be called angle 1 or angle 3 , or angle 5, and so on.
- Angles are measured using a tool known as a protractor
<h3>Measuring of an angle using a protractor</h3>
- To measure the angle, the mid-point of a protractor is placed on the vertex of the angle.
- Then lining up one side of the angle with the zero line of the protractor.
- Then read the degrees where the other side crosses the number scale.

Answer:
She can finish 4 puzzles.
Step-by-step explanation:
3/4+3/4=1 1/2
1 1/2+ 1 1/2= 3(hours)
That means that there are four 3/4s and that also means she does 4 puzzles in 3 hours.
Hope this helps!^_^
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.
21
4 = 420= 15 bracelets

20
(as a whole number there was no fraction or remainder to round off)
