Assuming LCD means Lowest Common Denominator
Assuming by "and" you mean adding the two
Well, you go by the multiples of 7;
7, 14, 21, 28, 35, 42, 49, 56, 63,<u> 70</u>
Multiples of 10;
10, 20, 30, 40, 50, 60, <u>70</u>, 80, 90, 100
Straight away you can see the lowest common multiple is 70,
Now to go about adding them,
2/7 * 10 (both sides) , 20/70
9/10 * 7 (both sides) , 63/70
Then you add the two; 20/70 + 63/70 - now we can add them because they share the same denominator
20/70 + 63/70 = 83/70 = 1 whole 13/70 (simplified)
<u>The LCD is 70
Quick tip, </u>to find a common multiple (not necessarily the lowest) multiply the two denominators.
Answer: C.Yes, because 3,502.86 is multiplied by the exponential term.
Step-by-step explanation:
3502.86 is the capital
1.15 is the interest
While ( t - 12 ) tells us about the period of time.
And f(t) is the amount of money in Gavin's investment account after t years
Answer:
x=1
Step-by-step explanation:
-3x=x-(6-2x)
-3x=x-6+2x
-3x=3x-6
6=3x+3x
6=6x
x=6/6
x=1

Answer:
D.
Step-by-step explanation:
Answer:
The will play the song at the same time by 4:12 pm
Step-by-step explanation:
here, we want to know the time both radio station will play the song after 3pm.
Mathematically to get this, we shall need to find the lcm of both 18 and 24. LCM stands for the lowest common multiple of both.
The lowest common multiple of both is 72.
This means that after 72 minutes, they will both play the song
So the time then would be;
72 + 3 = 4 : 12 pm
