Answer:
13/14 is greater
Step-by-step explanation:
Find the lcm for both:
<u>9 x 7 </u> = <u>63</u>
10 x 7 70
<u>13 x 5 </u> = <u>65</u>
14 x 5 70
so therefore 13/14 is greater since it has a greater value when finding the lcm
Answer:
x= 9 y=2
Step-by-step explanation:
Add up the equations vertically to eliminate y.
-x=-9
change the signs:
x=9
substitute the given value of x into the equation 2x-4y=10
2(9)-4y=10
18-4y=10
4y=8
y=2
Answer:
c) the marble is either red or green?
Step-by-step explanation:
First let us assume all black cards, the numbers that will
result in 24 is:
2 * 12
3 * 8
4 * 6
Similar case with the red cards:
-2 * -12
-3 * -8
-4 * -6
Assuming the product can be negative, so we can also take
the combination of two cards (1 red and 1 black):
2 * -12
3 * -8
4 * -6
-2 * 12
-3 * 8
-4 * 6
<span>So there are a total of 12 combinations.</span>
