Answer:
B.
Step-by-step explanation:
$195.42 - $50 = $145.42
$195.42/30% = 136.79
Again, simplify.
4x - 5.
x - 1.25. Hope it helps!
Answer:
1 + 4x = ?
Step-by-step explanation:
You need the value of X to solve this.
First add 3x and x and you get 4x
Then multiply the value of x by 4 and add 1 to that and that's the answer.
This is a multiplication problem.
3*3/4 is equal to (3*3)/4, which is equal to 9/4. This can be further simplified to the mixed number 2 1/4
This is an arithmetic series,
so
S(n) = (n/2)*(a(1)+a(n))
S(25) = (25/2)*(a(1)+a(25))
n=25
a(n) = 3n-2
a(1)= 3*1-2=1
a(1)=1
a(25) = 3*25-2=75-2=73
a(25)=73
S(25) = (25/2)*(1+73)=(25/2)*74=925
S(25)=925
Answer : 925
