Answer:
28 - 4n
Step-by-step explanation:
What is the recursive formula for this sequence? 24,20,16,12
the sequence first term is 24
a= 24
Common difference (d) = T2 - T1 = T3 - T2
d = 20-24 = 16 -20
d = -4
Formula for nth term
Tn = a + (n-1)d
Tn = 24 + (n -1)-4
Tn = 24 -4n + 4
Tn = 28 - 4n
= 28 - 4n

Answer:
B
Step-by-step explanation:
An even number is a number divisible by 2 and be an integer. An example would be 4/2 = 2
An incorrect even number would be 5
5/2 = 2.5 which isn't odd or even because it isn't an integer.
The base is 3+(x), altitude is x so substitute. Now we know the area of a triangle is base X height X 1/2. Substitute again! 1/2 (3+x)(x)=35. Multiply both sides by 2 to cancel out the 1/2. Now you have (x)(x+3)=70 and you have to foil out the left side x^2+3x=70. Subtract 70 on both sides x^2+3x-70=0. Find two numbers that multiply to -70 and add to 3. Solve (x+10)(x-7)=0. the x value is 7. since you can't have negative length values. Substitute 7 into 3+x for the base so you know the base is 10 and the height is 7.
Answer:
Step-by-step explanation:
12 men and 18 women: x1; 14 days; y1
8 men and 16 women: x2; ?; y2
12/18 simplified is equal to 2/3
8/16 simplified is equal to 1/2
This is a direct proportion, thus we can say that:
(1/2*14)/(2/3)=y2
7/(2/3)=10.5 days
I hope this helped you get out of homework trouble :D

Answer: 40 questions
Step-by-step explanation:
set it up as an equation
38/x = 95/100
cross multiply
95x=3800
solve for x
x=40
