Answer:
n=15
Step-by-step explanation:
5(n+1)=2n+20
U start by expanding the first term which will give you 5n+5
Then after that u collect like terms giving u
5n-2n=20-5
Finally u evaluate it giving u
n=15
Answers:
The length of XY is 4
The length of ZW is 6
Because we don't get the same length (for XY and ZW), this means that the segments are not congruent.
-------------------------------------------------------------
To find the length of segment XY, you can count the number of spaces between -7 and -3 to get 4 units. Or you can subtract and use the absolute value notation to ensure the result is positive
|-7-(-3)| = |-7+3| = |-4| = 4
Do the same for segment ZW.
|2-8| = |-6| = 6
Answer:
Step-by-step explanation:
<u>This is the permutation of 4:</u>
- 4P4 = 4! = 1*2*3*4 = 24 ways
2/7 because both 8 and 28 are divisible by 4
Answer:
$42.26
Tom spent more on tax ($1.54 vs his cousin's $0.72)
Step-by-step explanation:
Tom: $22 x 1.07 = $23.54
tax spent = 22 x 0.07 = $1.54
Cousin: $18 x 1.04 = $18.72
tax spent = 18 x 0.04 = $0.72
Total= $23.54 + $18.72 = $42.26
