Answer:
n < 20
Step-by-step explanation:
2n – 1 < 39
Add 1 to each side
2n – 1+1 < 39+1
2n < 40
Divide each side by 2
2n/2 < 40/2
n < 20
Answer:
(b) Both vertical and horizontal reflection
Step-by-step explanation:
The figure will be a horizontal reflection of itself about any vertical line through two of the smaller 6-pointed stars.
The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.
the pattern has both vertical and horizontal reflection
__
<em>Additional comment</em>
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
Make them both improper fractions.
77/10 - 19/5
Give them common denominators (multiply the second fraction by 2)
77/10 - 38/10
Subtract
39/10 = 3 9/10
-37m = 12
plug in the numbers:
(-28)(-37) ≠ 12
(-26)(-37)≠12
(26)(-37)≠12
(28)(-37) ≠ 12
idk none of the given answers are correct. Sorry.
<u>Answer:</u>
9c + 10 (see below)
<u>Step-by-step explanation:</u>
To find how much Chris spent on tickets, you can write an expression to represent the situation:
$9c
You can do this to find how much Michael spent as well:
$10m
To find how much Chris and Michael spent combined, add their two costs:
9c + 10
