C. 35 because if it is 35 roses, it will have to be 7 tulips. Divide 35 by 7 and get 5, and divide 7 and 7 to get 1.
In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression with common difference of 2.
Answer:
125
Step-by-step explanation:
The value of x can be found by making use of the sum of angles of a hexagon.
__
<h3>angle sum</h3>
The sum of angles of an n-sided convex polygon is 180°(n -2). For a hexagon, which has 6 sides, the sum of angles is 180°(6 -2) = 720°.
__
<h3>setup</h3>
The listed angle values must total 720°.
(x -30)° +(x +25)° +110° +115° +x° +x° = 720°
4x° +220° = 720° . . . . . collect terms
__
<h3>solution</h3>
Subtract 220° to get the x-term by itself.
4x° = 500°
x = 125 . . . . . . . . divide by 4°
