Angles on a straight line add to 180°, so:
4x + 90 + 2x + 72 = 180
6x + 162 = 180
6x = 18
x = 3
I hope this helps!
Fractions is the correct answer
Answer:
T = a + (n-1)d
Step-by-step explanation:
The arithmetic progression formula could be used to represent the series
T = a + (n-1)d
Where a = number of miles before increase
d = intended additional number of miles each day
n= number of days
Hence on the 2nd day, number of miles to be covered by Jeff will be
T = a + (2-1)d = a + d
7b - 2b + 3 - 1 = 0
(7b - 2b) = 5b
3 - 1 = 2
Thus:
5b + 2 = 0
5b = -2
b = -2/5 = -0.4
Answer:
<em>y = -2x - 4</em>
Step-by-step explanation:
<em>y + 1 = -2x - 3</em>
<em>Subtract 1 from both sides to get the y by itself</em>
<em>y = -2x - 3 - 1</em>
<em>Simplify (Combine Like terms)</em>
<em>y = -2x - 4</em>
