What is the LCD of 2/7 and 9/10

Answers

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, 70
Multiples of 10;
10, 20, 30, 40, 50, 60, 70, 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)

The LCD is 70

Quick tip, to find a common multiple (not necessarily the lowest) multiply the two denominators.

The least common denominator or LCD is 70 because for
10=10,20,30,40,50,60,70,80
7=7,14,21,28,35,42,49,56,63,70,77
and 70 is the least common denominator of 10 and 7 so 70 ims your answer

x-4y=5

y=-7
x+21=-2
x=-23
HOPE I HELPED!!!

well if x = 3y - 2, then everywhere u see and x remember it equals 3y - 2
so (3y - 2) - 4y = 5 then u distribute
-3y + 2 - 4y = 5 then combine the y's
-7y + 2= 5 then subtract 2 from each side
-7y = 3 then divide -7 on both sides
y = 3/-7
x = -3.28

Roland is picking out a snack. He has an apple, a pear, a banana, and an orange to choose from. Roland is going to pick one at random and wants to know what the chance that he will pick a bananna? Identify the action, the sample space, and the event.

Answers

Since there are 4 options and only 1 banana, there is a 1/4 chance he will pick a banana. I'm not sure what you mean by the last few questions? I think the sample space is an apple, pear, banana, or an orange. And the event is banana?

Ω = 4 set all equally probable events
aplle, pear,banana, orange
A = 1 random event favorable
banana

$P(A) = (A)/(omega) = (1)/(4)$

Roland choose once and has one chance in four that will draw the coveted banana. Therefore, the probability of this event is 1/4

Answer 1/4
