Answer:
with
Step-by-step explanation:
We can study what happens day by day starting with day one (1) to understand how the recursive relation can be constructed:
Day # Number of stamps What is added relative to previous day
1 d1 = 80 + 1 = 81
2 d2 = 81 + 2 = 83 d2 = d1 + 2
3 d3 = 83 + 4 = 87 d3 = d2 +
4 d4 = 87 + 8 = 95 d4 = d3 +
5 d5 = 95 + 16 = 111 d5 = d4 +
6 d6 = 111 + 32 = 143 d6 = d5 +
(n+1) d(n+1) = dn +
The values of angles are 140 and 20
• In plane geometry, a figure which is formed by joining of two lines that share a common point is called as the angle. The two lines or rays are called as the sides of the angle and the common point is called the vertex.
• In geometry there are types of angles such as complementary angles, supplementary angles, acute angle, obtuse angles. Complementary angles are the angles whose sum is equal to 90. Supplementary angles are the angles whose sum is equal to 180.
According to the question
We are given that one angle is -7x and the other angle is -2x
Using formula of supplementary angles
-7x + (-2x) = 180
-7x -2x = 180
-9x = 180
-x = 20
x = -20
The value of x is -20
The value of angle – 7x = -7(-20) = 140
The value of angle -2x = -2(-20) = 40

Answer:
(3)(-225) and -225(3).
Step-by-step explanation:
First, since ¨in debt¨ is describing negative value, all of the expressions that have positive 225 is incorrect. Also, since the term ¨triple¨ is describing multiplcation, any expression that does not have multiplication is also incorrect. This process of elimination leads to two answers, which both are correct.
