Answer:
Explanation:
f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3
f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2
f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6
f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2
f(7) = (7-1) • 3/2
f(7) = 6 • 3/2
f(7) = 9
100% = 1
Because:to have 100 percent of something, you must have one whole. One whole equals 100% and the same backwards. I hope this helps!
So, the correct answer is equals =
Answer: domain: 4, -2, 0, 1/2, 1, -3, 100
Range: 19, 77, 10, 9/5 10, 0, 100
Step-by-step explanation:
Let us take the second equation first
2a + 2b = 6
Dividing both sides by 2 we get
a + b = 3
a = 3 - b
Putting the value of a in the first equation we get
3a + 4b = 9
3(3 - b) + 4b = 9
9 - 3b + 4b = 9
b = 9 - 9
= 0
Now putting the value of b in the second equation we get
a + b = 3
a + 0 = 3
a = 3
So the value of the unknown variable a is 3 and the value of the unknown variable b is 0.
Person = 1 head and 2 legs
horse = 1 head and 4 legs
p +h = 74
p = 74-h
2p +4h = 196
2(74-h) +4h = 196
148-2h +4h = 196
148 +2h = 196
2h = 48
h = 48/2 = 24
24 horses
50 people
answer is B
