Step-by-step explanation:
5n - 2 => 2 less than 5 times a number
2(5 + n)=> Twice the sum of 5 and a number
2n + 5 => The sum of twice a number and 5
5n/2 => Half of <u>5</u> times a number:
2 - 5n => The product of 5 and a number less than 2
There are 24 permutations.
The number of permutations of 4 objects taken 4 at a time is given by
4!/(4-4)! = 4!/0! = 4!/1 = 4! = 24
Answer:
x = 12
Step-by-step explanation:
<1 and the 142-deg angle are vertical, so m<1 = 142 deg
The angle measuring 3x + 2 and <1 are same-side interior angles. If the lines are parallel, then those two angles are supplementary.
3x + 2 + 142 = 180
3x + 144 = 180
3x = 36
x = 12
Answer:
13.375
Step-by-step explanation:
you have to add 28 ± 17 = 45 ± 8.857 = 13.375
Answer:
A.(26)X =1
26x =1
divide both sides by 26 to make x the subject
26x/1=1/26
x = 1/26
Step-by-step explanation:
B 50(x) =1
50x =1
x =1/50
