Answer:
25 dollars times 0.20
Step-by-step explanation:
A sequence is said to be arithmetic if every couple of adjacent elements differ by the same number. If this is the case, that constant number is called the common difference.
This sequence is arithmetic, because the difference between every element and the previous one is
So, the common differnece is 3.4, because every couple of adjacent terms differ by 3.4
Answer:
Step-by-step explanation:
Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.
Answer:
Step-by-step explanation:
Slope m = 1
Point (1;8)
x1 = 1 and y1 = 8
y - y1 = m(x - x1)
y - 8 = 1(x - 1)
y - 8 = x - 1
y = x - 1 + 8
y = x + 7
