Answer:
x 45
___ = ____ (solve for x) = 39.6
88 100
88 + 39.6 = £127.60, was the original price.
Answer:
The slope is 3
Step-by-step explanation:
Slope= (y2-y1)/(x2-x1)
(4-1)/(4-3)= 3/1=3
The slope is 3
Keep in mind that:
- the sum of the interior angles of every triangle in existence is 180 degrees
- the base angles of isosceles triangles are congruent
With this information, I have created a diagram. I encourage you to always draw a diagram when you can - it aids in the solving process.
Now, to find <em>a</em>, set the measures of the interior angles equal to 180.
(<em>a</em> + 15) + 7<em>a</em> + 7<em>a</em> = 180
Solve for <em>a</em>.
<em>a</em> + 15 + 7<em>a</em> + 7<em>a</em> = 180
15 + 15<em>a</em> = 180
15<em>a</em> = 165
<em>a</em> = 11
Find the angle measures by plugging 11 for <em>a</em>.
<em>a</em> + 15
(11) + 15
26
7<em>a</em>
7(11)
77
Check your work by adding the angles measures.
77 + 77 + 26 = 180

Answer:</h3>
<em>a</em> = 11
Each base angle measures 77 degrees and the vertex angle measures 26 degrees.
If y varies directly with x, then whatever is done to y is also done to x, and vice versa.
All of the answers relate to when the value of y is positive 1, meaning we have divided the original y by -10.
We must also do this to x, as they are directly proportionate, meaning x = 2 now becomes x = -1/5
Therefore the answer is [B]
