Answer:
36h + 75 < 1200
solve:
36h + 75 = 1200
36h = 1125
h = 1125 divided by 36 = 31.25.
Therefore, Traci has to dance a minimum of 31.25 hours to raise $1200
Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9
Answer:
1.29 * 10^9.
Step-by-step explanation:
That is 1.4 * 10^9 - 1.1 * 10^8
= 14 * 10^8 - 1.1 * 10^8
= 12.9 * 10*8
= 1.29 * 10^9.
Answer: f(3)=-20
Step-by-step explanation:
If you look at f(x) and f(3), you can see that 3 is in place of x. That means when x=3, what is f(x). You plug in x=3 into f(x) and solve.
f(3)=-2(3)²-2
f(3)=-2(9)-2
f(3)=-18-2
f(3)=-20
